THE PRICE TAG ON DESIGNER BABIES:
MARKET SHARE LIABILITY
Abstract: The prospect of genetically modifying humans has loomed over the pub-
lic for decades. Now, science fiction is becoming reality. New technology and ex-
panding research are positioned to make genetic alteration a routine, pre-concep-
tion appointment. For several years, China has been experimenting with germline
editing on non-viable human embryos. In April 2016, the UK also approved a
group of scientists to begin similar research. In the United States, genetic engineer-
ing is a multibillion-dollar industry. Although ethical debates over human genetic
modification have checked the industry, the potential for clinical trials has become
a reality as companies race to dominate the technology. In light of the potential im-
pact of problematic genetic alterations on future generations, the harm inflicted on
victims parallels the Diethylstilbestrol cases of the 1980s, signaling a re-emergence
of market share liability.
INTRODUCTION

tional Intelligence, James Clapper, categorized genome editing as a “weapo[n]
of mass destruction and proliferation.”
2
In the Worldwide Threat Assessment of
the US Intelligence Community report, Clapper stated that new technology has
realized the possibility that flawed heritable human genetic alterations may
result from manipulation of the human genome through “deliberate or uninten-
tional misuse.”
3
The report added a caveat that the complexity of the human
genome still poses a limit on the ability of researchers to manipulate the ge-
nome effectively.
4
Nonetheless, the technology is available.
5
The past few years2015 in particularhave seen the emergence of
simple, precise, and affordable DNA altering techniques.
6
These techniques
include the use of clustered regularly interspaced short palindromic repeats
(“CRISPR”) and the enzyme, protein-9 nuclease (“Cas9”).
7
Using CRISPR-
Cas9, scientists can effectively and efficiently alter the human germline.
8
“Human germline editing” involves targeting DNA in human sperm, eggs, or
embryos that is passed on to future generations through normal reproduction.
9
The potential benefits of germline editing to human society are enormous.

Researchers are hopeful that they can reduceor eliminatethe risk of herit-
able diseases such as Huntington’s disease.
11
Likewise, researchers want to
introduce beneficial genes to strengthen one’s body and prolong good health.
12
Nonetheless, CRISPR-Cas9 is not a magic bullet.
13
According to Dr.
Keith Joung, a renowned pathologist at the Massachusetts General Hospital
and Harvard Medical School, more research is needed to reduce off-target gene
editing before CRISPR-Cas9 can be used in clinical applications.
14
“Off-
targets” occur when the splicing enzyme matches the designated sequence to
the wrong gene causing potentially disastrous side-effects.
15
For instance, an
off-target impact may result in creating a higher likelihood of a future cancer
diagnosis.
16
While scientists remain hopeful that they will be able to more ac-
curately assess the risk of unintended editing through advancing technology,
the effects remain unclear for now.
17
Off-target gene altering may create unin-
tended and uncertain changes in a gene pool that could last for generations.
18
One major difficulty with off-target editing is creating a legal scheme that
will compensate victims whose symptoms may not appear for generations.

Bacteria and viruses differ in that bacteria are more

Viruses invade bacteria cells by attaching

As opposed to other gene editing methods, like zinc finger nucleases
(“ZFN”) and transcription activator-like effector of nucleases (“TALEN”),
CRISPR-Cas9 is more precise, simple, and affordable.
43
Both ZFN and
TALEN require more complicated processes using a customized protein rather
than a short RNA sequence.
44
By contrast, scientists using CRISPR can encode
a single guide RNA with the proper gene sequence for editing.
45
The Cas9 en-
zyme will read the RNA and make the genetic cuts.
46
Unlike traditional gene
editing methods, CRISPR-Cas9 increases efficiency by allowing scientists to
alter multiple genome sites at once.
47
This technology is both readily available
and simple; a scientist can edit a DNA strand for a mere sixty-five dollars.
48
2. Current Uses and Regulations of Human Germline Editing
In an outpouring of recent experiments, the CRISPR-Cas9 methodology
has enabled scientists to treat muscular dystrophy in mice, counteract drug-
resistance in insects, increase physical strength in dogs, generate virus-resistant
pigs, and modify crops for greater protection.
49
In April 2015, Chinese re-

alarm system to notify the bacteria that a foreign invader has entered and that it must rid itself of the
material immediately. Id. Specifically, the Cas-9 protein is the enzyme from the bacterium Streptococcus
pyogenes used to initiate the cutting technique that scientists have discovered makes the gene editing
process much easier. Benazir & Abhinayani, supra note 6, at 3338.

In 2017, researchers in the United States also edited human
embryos using CRISPR-Cas9.
51
The moral dilemma surrounding human genet-
ic editing has remained a heated issue.
52
About five hundred scientists gathered
in Washington D.C. in 2015 for the International Summit on Human Gene Ed-
iting.
53
The Summit established a worldwide consensus to prohibit human
germline clinical trials using this technology.
54
While the Summit agreed that
research was “clearly needed and should proceed,” it also concluded that it
would be “irresponsible” to create a genetically engineered human at such an
early stage of research, citing safety and moral concerns.
55
In contrast to this
2015 worldwide consensus, the National Academy of Sciences, Engineering,
and Medicine, in February 2017, expressed its support for editing a child’s
germline under a strict regulatory framework: the circumstances require the

As scientists continue to debate the ethical questions of human genetic
modification, some countries maintain loose regulations on the practice while
at least twenty-five countries have prohibited human germline engineering en-
tirely.
57
China has created “guidelines”but not lawsregulating the industry,
and Japan, Mexico, and South Africa, have ambiguous policies about whether
or not human germline editing research is allowed.

zil, Germany, and Australia do not allow human germline genetic experimenta-
tion at all.
59
In 2016, the British Human Fertilization and Embryology Authori-
ty (“HFEA”) granted the first license by a national regulator for scientists to
edit the human germline using human embryos for research.
60
In the United States, there is no federal ban on germline engineering and
the government only places restrictions on the practice.
61
In 2015, Congress
passed the United States Federal Omnibus Bill, which prohibits any Federal
Drug Administration (“FDA”) funding to be given to research on human
germline genetic engineering.
62
The National Institutes of Health (“NIH”)
manages funding of gene transfer research through the Recombinant DNA Ad-
visory Committee (“RAC”).

Although the FDA would most likely regulate genetically modifying humans
in the U.S., it does not officially ban potential clinical application.

The biotechnology industry for genome editing is expanding rapidly be-
cause of revolutionary technology like CRISPR-Cas9.
67
In May 2015, Mar-
ketsandMarkets published a report predicting that the genome editing market
will be worth $3.5 billion in just four years.
68
In Boston, three start-up compa-
nies have partnered with pharmaceutical companies such as Bayer and Novar-
tis and raised an aggregated $1 billion.
69
In fact, the pharmaceutical giant No-
vartis has funded and contracted with the biotechnology start-up Intellia to de-
velop CRISPR techniques to treat cancer and to research “limited in vivo” ap-
plications of the technology.
70
A large concern with gene editing is that companies will exploit CRISPR-
Cas9 to perform risky experiments since it is cheap, simple, and yields high
rewards.
71
Sir Venki Ramakrishnan, the 2009 Nobel prize winner in chemistry,
echoes the fears of many in the scientific community that “once a technology
is feasible, we may well regulate it, but someone somewhere may start using it

3. Potential Consequences and Risks of Human Germline Editing
As CRISPR-Cas9 techniques advance, off-target consequences for individ-
uals and subsequent generations are of immense concern.
74
In a 2013 study on
Duchenne muscular dystrophy (“DMD”), which results from a genetic mutation
on the X chromosome and causes muscle deterioration, Dr. Eric Olson success-
fully treated DMD afflicted mice by editing their genome using CRISPR-Cas9.
75
Although off-target consequences were rare in that specific experiment, Dr. Ol-
son acknowledged that CRISPR genome editing can unintentionally cause life-
long changes to an organism’s DNA.
76
Many scientists worry that treating a hu-
man with DMD using CRISPR-Cas9 technology may lead to generations of un-
foreseen and possibly irreparable harmsuch as removing someone’s protective
gene for cancer.
77
Thus, scientists worry that human manipulation of the genome
may lead to long-term negative impacts on the gene pool itself.

In the first reported human germline genetic modification, Chinese re-
searchers replaced the gene for a blood disorder called β-thalassaemia in twen-
ty-eight out of seventy-one non-viable embryos.
79
In the process, they caused
unwanted alterations in other parts of the genome.
80
In subsequent research,
Chinese researchers attempted to insert a mutated gene into the germline to
create HIV resistance and were successful in a mere four out of twenty-six
non-viable embryos and again, caused unwanted mutations.
81
Notably, even if scientists can precisely edit the targeted gene, unintended
causal reactions may still ensue.
82
This is because genes that increase the risk
for some diseases may actually decrease the risk for others.
83
For instance, if a
genetic company targets someone’s CCR5 gene, which increases the risk for
contracting West Nile, removal of the gene will also rid her of an important
protection from HIV.

Likewise, altering someone’s MC1R gene in order to
produce vibrant red hair can also increase her risk of melanoma.

B. Product Liability Issues and DES Cases for Comparison
1. DES’s Generational Impacts
Diethylstilbestrol, commonly known as “DES,” was hailed as a miracle
drug that shielded pregnant women from miscarriages, premature labor, and
other pregnancy complications.
88
DES was manufactured in 1938 by research-
ers who synthesized estrogen into pill-form so that it could be taken orally.
89
In
1939, Chicago physiologists discovered that giving DES to pregnant rats and
mice caused damage to a developing fetus and produced miscarriages.
90
De-
spite these findings, pharmaceutical companies successfully persuaded the
FDA to allow them to continue to prescribe DES to pregnant women.
91
The drug was routinely prescribed from 1940 to 1971, until researchers de-
tected a strong correlation between DES and cervical and vaginal cancer.
92
At this
point, the damage could not be undone since about 510 million children were
exposed while in utero.
93
As revealed in later studies, young daughters of women
who took DES while pregnant had cancer risks forty times higher than non-
exposed daughters.
94
These risks increased as the daughters aged.

potential DES side effects has continued as scientists and doctors strive to identi-
fy and treat DES exposed victims from diseases that escalate or appear with
age.
96
With generations of negative health effects and increased risks for diseases
over time, plaintiffs have struggled to find a legal remedy for their harm.
97
2. Tort Liability Challenges and Innovations
Because of the extraordinary circumstances surrounding the DES disaster,
including latent health effects and the vast number of unidentifiable defend-
ants, DES victims argued for a novel theory of tort liability.
98
As the Supreme
Court of California, in Sindell v. Abbott Laboratories in 1980 explained, one of
the greatest predicaments was whom to hold responsible since finding the spe-
cific DES manufacturer for a prescription taken decades earlier was nearly im-
possible.
99
Drug manufacturers often did not have direct interaction with con-
sumers, so most plaintiffs could not retrace or remember what a specific pill,
taken years ago, looked like.
100
The Sindell court noted that consumer harm
from DES exposure often did not show up for at least a generation, and manu-
facturers did not prescribe its drugs, let alone maintain records of who received
its drug.
101
Therefore, under traditional tort law, a DES plaintiff could not re-
enced a 1.7% greater risk for breast cancer at ages forty or older, and a 35.4% greater risk for preterm
delivery. Robert N. Hoover et al., Adverse Health Outcomes in Women Exposed in Utero to Diethyl-
stilbestrol, 365 N
EW ENG. J. MED. 1304, 1306 (2011) (assessing future DES impacts on women ex-
posed in utero).

See Role of DES Cohort Studies, CTRS. FOR DISEASE CONTROL, https://www.cdc.gov/des/
consumers/research/understanding_cohort.html [https://perma.cc/5X7U-7A2C] (explaining that DES
daughters typically do not need to worry about infertility, ectopic pregnancy, or other endocrinal diffi-
culties until after their thirties). In fact, Cohort studies compiled by the Center for Disease Control, still
monitor about 15,000 exposed individuals since many cancers are not visible until later in life. See id.

cover unless she could identify the specific manufacturer of the pill she ingest-
ed years ago.
102
In response to these DES cases, tort law evolved to allow plaintiffs to re-
cover despite a pills generic formula and the inability to find specific defend-
ants.
103
Without a change or compromise in tort law, recovery proved “insur-
mountable” to plaintiffs whose cancer arrived years later.
104
This new tort theo-
ry assigned liability via a company’s DES market share.
105
The Sindell court
was the first to adopt the market share liability theory and held that plaintiffs
could recover against pharmaceutical companies according to their participa-
tion in the market.
106
The principle emanated from the “alternative liability”
theory as expressed in the 1948 Supreme Court of California case, Summers v.
Tice.
107
Summers held that a plaintiff, whose eye was injured by one of two
negligent hunters, could hold them jointly and severally liable despite not
knowing which one was ultimately responsible.
108
This theory relied on a fair-
ness rationale: both hunters were wrongdoers, so the burden should shift from
the plaintiff to the defendants to prove otherwise.

3. Successes and Failures in Providing Remedies to DES Victims
One of the problems with compensating DES victims is the inability to
predict with certainty what damages are sufficient to cover present and future
health complications.
110
The effects of DES correlate with a victim’s age in
that breast and vaginal cancer risks increase dramatically as the victim gets
older.
111
Accounting for such risks when filing a lawsuit can be difficult.
112
Particularly, once a plaintiff is on notice, she risks losing her claim through the
statute of limitations unless a state has instituted revival statutes which allow
DES claims to be brought once effects are experienced, and not just once she
knows she was exposed to DES.
113
On the other hand, with little information
except health impacts, a court may find it necessary to restrict standing to a
specific generation.
114
In Enright v. Eli Lilly and Company in 1988, the Court
of Appeals of New York did not recognize a handicapped grandchild’s claim
against DES manufacturers since the evidence was too obscure and attenuated
to have a jury trial.
115
Courts have been sympathetic to plaintiffs concerns about developing
cancer and have awarded damages for future harm.
116
In 1995, the New York
state trial court in In re New York County DES Litigation affirmed a jury ver-
dict awarding damages ranging from $2,500$58,000 for future health compli-
cations for multiple DES plaintiffs.
117
Notably, the court recognized that future
damages served as valid compensation for the plaintiffs’ “unique, far-ranging
and severe physical and psychological injuries.”
118
As DES exposed children begin to experience latent health effects, there
remain numerous pending DES cases across the country.
119
Nonetheless, many

Recently, four sisters diagnosed with breast cancer, allegedly caused

Although market share liability may be
inadequate to fully compensate individuals who fear suffering from painful

tional harm are unlikely to recover since they must prove that the defendant’s
productsuch as DES, asbestos, a vaccine, or genetic alterationcaused their
individual harm.
126
Courts are often split on whether or not to recognize the doctrine of mar-
ket share liability, thus making its application beyond a narrow category of
“fungible products” uncertain.
127
If a harmful product is interchangeable, then
a court is more comfortable allowing proportional recovery among plaintiffs
since the manufacturers are, in theory, equally culpable for its distribution.
128
Sindell narrowed the scope of the new market share liability theory by suggest-
ing that any future claims must involve products that are 1) interchangeable, 2)
have equivalent risks across company lines, and 3) are controlled in the market
through concerted efforts on behalf of the industry.
129
Thus, courts have largely
restricted use of this doctrine to classic DES-type cases and treated its use as
an exception to normal tort doctrine.

This Part analyzes the limitations of extending market share liability be-
yond the DES context.

market share liability, fungibility of the product.

victims when injuries are not present for decades and are passed on to subse-
quent generations.
134
A. Fungible Product by Design
In order for liability to be spread among companies based on market par-
ticipation, the distributed product must be interchangeable between compa-
nies.
135
In 1980, the California Supreme Court, in Sindell v. Abbott Laborato-
ries, first applied market share liability when hundreds of manufacturers pro-
duced DES using the same generic formula and then marketed their product to
pregnant women.
136
The court found that each manufacturer contributed
roughly the same percentage of harm to plaintiffs based on market contribu-
tion.
137
The relevant inquiry, in determining whether market share liability is ap-
propriate, is whether a company’s product presents a similar enough risk of
harm to consumers or the public such that their liability can be based on the
percentage of their market involvement.
138
For instance, in a 2005 consolidated
multi-district lawsuit, the United States District Court for the Southern District
of New York in In re Methyl Tertiary Butyl Ether (“MTBE”) Products Liability
Litigation extended the use of market share liability to allow “innocent water
users” to recover from petroleum distributors that delivered gasoline contain-
134
See infra notes 164–179 and accompanying text.
135
See DOBBS, supra note 125, § 194. For market share liability to be fairly administered, a com-
pany must be connected to the harm alleged by the plaintiff. See id. Even if not directly connected, a
company can still be culpable for distributing a product that resulted in harm to consumers. See id. In
the DES cases, the pills were manufactured using the same generic formula, which promoted a fair-
ness rationale for holding each of the manufacturers culpable for how many drugs they had on the
market. See id. In addition to the DES context, the court in Wheeler v. Raybestos-Manhattan found
asbestos concentrations in brake pads to be uniform enough across the industry to hold manufacturers
liable based on market contribution. See Wheeler v. Raybestos-Manhattan, 8 Cal. App. 4th 1152, 1156
(1992). Before holding genetic companies uniformly responsible for future injuries based on market
participation, courts will need to find that genetic companies use the same process for performing the
germline modification to target the same genetic disease. See id.
136
See Sindell, 607 P.2d at 935–36 (justifying market share liability as the means for compensat-
ing plaintiffs by a culpable industry rather than allowing manufacturers to escape liability merely
because they could not be directly identified). The court in Sindell measured market share liability
based on the likelihood that any of the defendants supplied the product which allegedly injured the
plaintiff by the percentage which the DES sold by each of them for the purpose of preventing miscar-
riage bears to the entire production of the drug sold by all for that purpose.See id. at 937. The court
noted that plaintiffs could not single out one particular defendant from hundreds of DES manufactur-
ers because they created and sold DES using an identical formula.See id. at 936.
137
See id. at 937. Specifically, the court noted that if the defendants, Eli Lilly and Company and
five or six other companies, contributed 90% of the DES that was on the market, then there would be
a 10% chance that the responsible defendant would not be held accountable. See id.
138
See DOBBS, supra note 125, § 194 (describing that for an industry to be accountable, the harm
of each manufacturers product must be equivalent in order to assign liability based on production).

ing the carcinogenic chemical MTBE.
139
The court was compelled by evidence
that defendants understood the risks of immense groundwater contamination
from mixing gasoline with MTBE and that any contamination could not be
traced to a single source.
140
As a result of active concealment by the defendants
and MTBE being fungible, the court allowed plaintiffs to recover damages un-
der the theory of market share liability.
141
Nonetheless, market share liability has been reserved almost exclusively
to the DES context because most products are not generic across an industry.
142
For example, in 1995 in Bly v. Tri-Continental Industries, Inc., the United
States Court of Appeals for the D.C. Circuit referred to market share liability
as a “last resort” largely limited to DES cases where each manufacturers
product is “identical.”
143
As a result, the plaintiff could not show fungibility
since the product at issue, benzene gasoline, was manufactured using different
formulas across the industry.
144
Thus, the harm that each manufacturer contrib-
uted could not be considered equal per product on the market because the vary-
ing concentrations of harmful benzene changed the severity of harm of the
product, making some companies more or less culpable than others.
145
Similar-
ly, allergy-causing latex gloves and harmful lead paint are not recognized as
fungible products since manufacturers assemble them with different quantities
of the harmful products.
146
Courts are hesitant to expand market share liability
when manufacturers use different quantities of a harmful substance in their
products, and/or the injury could be attributed to another product altogether.

ridden duct tape since the harmful asbestos concentrations varied significantly by brand type); Case v.
2018] The Price Tag on Designer Babies: Market Share Liability 339
In the 1987 Supreme Court of Oklahoma’s ruling in Case v. Fibreboard Cor-
poration, the court found that asbestos would rarelyif at allbe a fungible
product like DES.
148
It found that “asbestos” generally referred to products
with varying concentrations of harmful minerals and the risk of exposure often
correlated with the type of asbestos product.
149
Moreover, courts’ applications of market share liability have important
distinctions.
150
For instance, in Sindell, the court applied market share liability
with an important caveat: if a manufacturer proved it could not have sold the
DES to the specific plaintiff, then it was excused from liability.
151
Alternative-
ly, in 1989 the New York Court of Appeals, in Hymowitz v. Eli Lilly and Com-
pany, ruled that it would apply a national market share liability theory based
on the “overall-risk produced” to the public and not specific causation to an
individual plaintiff.
152
Therefore, under that approach, even companies who
could prove they definitely did not cause the plaintiffs injury were still liable
based on their national market share so long as they were culpable for the
overall harm.

148
See Case, 743 P.2d at 1065–66 (contrasting asbestos products and the varying risks in compo-
sition and types of products with DES pills, which were generically administered to pregnant women).
Of note to the court, “asbestos” is the name of a family of minerals and can be a combination of more
than thirty different minerals. See id. at 1065.
149
See id. at 1065; Nace, supra note 104, at 41415 (explaining that most courts have not applied
market share liability in the asbestos context because of the difficulty in attributing the specific harm
to a product). People are exposed to countless asbestos products in the workplace or at home resulting
in a product identification problem similar, yet different, than DES in that it is not merely one harmful
product. See id.
150
See Nace, supra note 104, at 396. States have adopted varying market share liability doctrines
depending on important notions of fairness and how liability should be determined. See id. at 406. In
Sindell, the court allowed companies to escape liability if they could prove they did not injure the
specific plaintiff with their product so that only manufacturers with some probability of contributing
to the specific injury and a substantial share in the sales could be held accountable. See Sindell, 607
P.2d at 937. Ambiguity in whether market share would be a percentage of the plaintiffs harm or a
percentage of the national market share resulting in less than a full recovery led to some varying inter-
pretations of Sindell. See Note, Market Share Liability: An Answer to the DES Causation Problem, 94
H
ARV. L. REV. 668, 67273 (1981) (analyzing court applications and interpretations of market share
liability). In Martin v. Abbott Laboratories, the court applied a theory of market share recovery that
the California Supreme Court later adopted in Brown v. Superior Court that assessed liability based on
a manufacturers harm to a particular plaintiff. See Brown v. Superior Court, 751 P.2d 470, 485 (Cal.
1988); Martin, 689 P.2d at 382. By contrast, the court in Hymowitz v. Eli Lilly & Co. departed from
this structure by focusing on the culpability of each defendant to the public and assigning liability
based on the risk of harm each contributed. See 539 N.E.2d at 1078.
151
See Sindell, 607 P.2d at 937 (refusing to extend market share liability to a defendant if she
proved her product could not have caused the plaintiff’s injuries).

Hymowitz, 539 N.E.2d at 1078.
153
See id. (“Nevertheless, because liability here is based on the over-all risk produced, and not cau-
sation in a single case, there should be no exculpation of a defendant who, although a member of the
market producing DES for pregnancy use, appears not to have caused a particular plaintiff’s injury.”).
340 Boston College Law Review [Vol. 59:319
B. Tracing Causation Across Broken Family Lines
While market share liability helps plaintiffs recover when a specific man-
ufacturer of the DES itself cannot be identified, proving that the product actu-
ally caused the injury is one of the greatest hurdles to compensation.
154
In re-
viewing studies on DES’s impact on mothers and their children’s increased
risk of cancer, some courts have found in favor of the plaintiffs so long as they
prove DES exposure.
155
Unfortunately, many plaintiffs impacted by DES can-
not recover because the causal connection is often too speculative to prove that
DES itself led to the negative health effects generations later as opposed to
other genetic risks, exposures, or activities.
156
Products that increase someone’s risk for contracting a common disease
or cancer in and of themselves are extremely difficult to associate with a par-
ticular defendant since the defendant can easily cast doubt on whether their
product was a “substantial factor” in causing the mainstream disease.
157
For
instance, a woman’s risk of breast cancer doubles from 2% to 4% if her mother
consumed DES while pregnant; however, countless other factors also increase
a woman’s probability of getting breast cancer.
158
In fact, the Center for Dis-
ease Control (“CDC”) has listed over fifteen risk factors that make a woman
more likely to develop breast cancer such as drinking alcohol and aging.
159
In
2008, in Borg-Warner Corporation v. Flores, the Supreme Court of Texas
The court sought to avoid a “windfall” scenario where manufacturers could escape liability because
they stayed in a local market or made their product “more identifiable,” yet remained equally culpable to
the public as a whole. See id.

found that as a matter of law the jury did not have sufficient evidence to find
that a plaintiffs lung cancer was caused by inhaling asbestos dust at work
when grinding asbestos-ridden brakes for more than three decades.
160
The
court highlighted that the plaintiff smoked, there existed over one hundred dif-
ferent causes for lung disease, and there was little evidence showing how much
asbestos the plaintiff had been exposed to when grinding brake pads.
161
Simi-
larly, in Case v. Fibreboard Corporation, the plaintiff also could not prove a spe-
cific asbestos product caused the injuries.
162
The court noted that the asbestos-
injuries could have come from any one of the three thousand asbestos products a
typical person encounters at work or at home.

C. Compensating a Broken Family Line: Collection
and Liquidity Problems
Compensating victims who suffer detrimental effects from a product that
increases the risk of developing a severe, latent health problem proves chal-
lenging, especially when the risk of harm continues to be passed down from
generation to generation.
164
Courts will have to estimate not only the claim-
ant’s present harm and future medical bills, but also that of potential children
who may suffer from the harm.
165
DES exposure increases cancer risks, which
are passed on through daughters, leading to a litany of negative health reper-
cussions still in existence today.
166
Due to varying court interpretations of market share liability, many vic-
tims could not recover if the manufacturer went out of business or proved it

See In re New York County DES Litig., 211 A.D.2d 500, 500 (N.Y. App. Div. 1995) (affirm-
ing the jury verdict for likelihood of disease damages). The court in In re New York County DES Liti-
gation held that reasonable compensationcould include future damages for an increased risk of
disease and medical appointments. See id. In Bichler v. Eli Lilly & Co., the Supreme Court of New
York affirmed a $492,842.39 jury award to a DES plaintiff, which included damages for her chil-
dren’s future cancer costs. See 436 N.Y.S.2d 625, 625 (App. Div. 1981).

quent generations and recapping a study that was published in the New England Journal of Medicine).

could not have sold DES to that particular plaintiff.
167
In Brown v. Superior
Court, the California Supreme Court in 1988 noted that it would not assign
liability to DES manufacturers that proved they did not and could not have
caused the injuries of the claimant.
168
By comparison, another interpretation of
market share liability was used in Hymowitz.
169
There, the court reasoned that
manufacturers were culpable to the public as a whole.
170
Thus, under that in-
terpretation, even if a manufacturer definitively proved it was not responsible
in a specific case, victims could still recover based on its contribution to the
national market.
171
Although allowing for recovery is the first step, a critical concern is how
manufacturers will compensate generations of victims for harm.
172
Companies,
like people, can become judgment-proof.
173
Many manufacturers subject to
latent tort liability will run out of money before not only the symptoms mani-
fest, but before the victims in subsequent generations receive compensation.
174
As illustrated through asbestos reorganizations in the 1980s, companies at-
tempted to use Chapter 11 of the Bankruptcy Reform Act of 1978 to shed
overhanging tort liability.
175
167
See Nace, supra note 104, at 396 (outlining the various market share liability theories across
states). In California, courts assess manufacturer market share liability based on their stake in the
relevant market but offer a complete defense if they can show there was no possible way they supplied
DES to the specific plaintiff in the case. See id. at 403–05; Brown, 751 P.2d at 485–87 (resolving an
ambiguity in the application of market share liability by determining that defendant manufacturers
will only be held severally liable).
168
See Brown, 751 P.2d at 485.
169
See Hymowitz, 539 N.E.2d at 1078 (assigning liability based on the risk of harm each manu-
facturer defendant contributed to the public).
170
See id. This is because each manufacturer was at fault for having released a dangerous product
into the public although the exact ramifications were unknown. See id.
171
See id. Because each manufacturer released a harmful product into the public, each was culpa-
ble based on their percentage of the market and should be held accountable on an industry-scale. See
id.
172
See Collins, 342 N.W.2d at 48 (explaining that many DES companies have left the market,
while others have entered, and there were uncertain records concerning the overall national production
of DES).
173
See MARK J. ROE & FREDERICK TUNG, BANKRUPTCY AND CORPORATE REORGANIZATION
336 (4th ed. 2016) (describing the institutional problem with mass tort compensation when companies
declare bankruptcy and future tort victims are unable to collect damages).
174
See id. (analyzing the problem of compensation in mass tort cases for victims who incur medi-
cal expenses at a later time after all possible distributions have already happened).
175
See 11 U.S.C. § 1102 (2012). Chapter 11 essentially lets companies write down their tort debt
and, perhaps more importantly, fix it at a known quantity. See id. One of Chapter 11s unforeseen conse-
quences is the attempt by companies to use Chapter 11 bankruptcy to skirt massive tort liability by reor-
ganizing. See Note, The Manville Bankruptcy: Treating Mass Tort Claims in Chapter 11 Proceedings, 96
HARV. L. REV. 1121, 1122 (1983) (predicting the future of Chapter 11 proceedings in mass tort claims).
Because there were many potential debtors, since the effects of asbestos exposure had yet to materialize,
asbestos companies, like Manville, tried to limit their future liabilities by having experts and not juries
determine the scope of each tort claimants recovery. See id. at 1132.
2018] The Price Tag on Designer Babies: Market Share Liability 343
In order to maintain company liability for DES, to allow for more directly
harmed plaintiffs to recover, and to meet evidentiary concerns, New York
courts applied a policy compromise in favor of limiting liability to the third
generation at the expense of other victims.
176
The Court of Appeals of New
York in 1991, in Enright v. Eli Lilly and Company, reduced the liability of DES
defendants to “manageable limits.”
177
Thus, it limited recovery only to first
generation DES victims and not to daughters and granddaughters despite suf-
fering from “malformations or immaturity of the uterus, cervical abnormalities,
misshapen Fallopian tubes, and abnormal cell and tissue growth.”
178
Evidently,
even if liability is established, court awarded recovery may not be enough in
light of courts’ self-designated restrictions on limiting pay outs.
179
III.
PREPARING FOR THE WORST AND PLANNING FOR THE
F
UTURE WITH MARKET SHARE LIABILITY
Genetic modification may feel like it is part of the scientific future, but
tests are already being done on non-viable human embryos and the industry is
heavily invested in the new CRISPR technology.
180
Market share liability of-
fers a solution for victims to recover when tortfeasors cannot be readily identi-
fied because of time or drug uniformity.
181
As genetic editing becomes the new
generic vaccine or commonly prescribed medication, states should adopt a
176
See Enright v. Eli Lilly & Co., 570 N.E.2d 198, 20304 (N.Y. 1991) (finding that the passage
of time and uncertain impact of DES exposure on subsequent generations requires a stopping point in
litigation). The court wanted to avoid measures of over deterrence and instead recognize a manufac-
turer’s breach of duty towards those directly impacted by the defective drugs. See id. at 204.
177
See id. at 203 (predicting that “manageable limits” requires limiting litigation to the third gen-
eration). Although the court in Enright did not list the factors for why it believed manageable limits
should be in place, it cited to the New York Court of Appeals case, Tobin v. Grossman, which listed
the following factors to be considered when limiting a defendant’s liability: “foreseeability of the
injury, proliferation of claims, fraudulent claims, inconsistency of the zone of danger rule, unlimited
liability, unduly burdensome liability, and the difficulty of circumscribing the area of liability.” Id.

form of market share liability so that genetic companies can predict their long-
term legal and liability costs before entering the market.
182
This Part argues that market share liability should be adopted in the ge-
netic modification context.
183
Section A discusses the likelihood of being able
to identify a specific genetic company as the source of harm, and argues that as
the process becomes streamlined, similar DES defendant identification prob-
lems will occur.
184
Section B examines germline engineering using CRISPR-
Cas9 as a fungible product comparable to DES pills and vaccines.
185
Section C
assesses the complications of company identification when a defective
germline procedure may not show itself for decades or generations down the
line.
186
Finally, Section D advocates for market share liability as a means of
compensating generations of victims and serving as a pre-market cost for com-
panies entering this risky industry.
187
A. Courts Should Adopt Market Share Liability for Harm
Arising from Genetic Alteration
Unlike DES manufacturers selling pharmaceutical drugs, one of the big-
gest differences in human genetic alteration is that businesses are in never-
before-chartered territory.
188
Any germline engineering transactions for the
first decade or so are likely to be highly contentious and heavily monitored by
journals, medical records and news reports.

Evidently, market share liability

may deviate in genetic engineering cases from generic pharmaceutical or as-
bestos cases because of the likelihood that plaintiffs will be able to identify the
proper defendants.
190
If defendants are readily identifiable, then market share
liabilityas it is currently understoodwould not apply.
191
The very reason
for establishing market share liability was to address the problem of an uniden-
tifiable defendant, and assign a percentage of liability to a market participant
because of its tortious market involvement.
192
On the other hand, if human germline engineering becomes a routine pro-
cedure for families, as predicted, then defendants may not be readily identifia-
ble.
193
Market share liability would be invaluable to victims of a defective genet-
ic procedure whose harm manifests decades later in their children or childrens
children.

like an assessment of their child’s genetic condition.

Presently, the worldwide pre-
natal testing market is expected to increase, between 2016 and 2022, at a rate of
28.85%.
197
With an expected $7.2 billion dollar market by 2022, the temptation
to use genetic scissors to eradicate chromosomal deformities prior to conception
are likely to mainstream germline modification at a rapid rate.
198
As a result of
widespread popularity and high demand, germline modifications are likely to
become so streamlined and generic that they may be used with such frequency
analogous to the prescription of drugs like DES.
199
B. Genetic Modification as a Fungible Product
To function like a fungible product, genetic companies would need to tar-
get the same genetic disease using the same modification process.
200
This
proves a more complicated inquiry than the DES cases since CRISPR-Cas9 is
a process, not a product like DES pills, and the altered gene may have reper-
cussions distinct to an individual’s genetic make-up.

may analogize the same formula used to manufacture DES, to companies using
the same gene modification process—CRISPR-Cas9to insert or remove a
specific gene.
202
Moreover, prescribed DES pills often varied by concentration,
which shows that courts allowed for some variance.
203
Unlike asbestos products, where market share liability has not been ac-
cepted, germline modification differs in that CRISPR-Cas9 is likely to be
streamlined among the industries.
204
Instead of thousands of products contain-
ing different variations of a drug or chemical, germline modification is likely
to be the same for individuals who have a specific genetic abnormality that is
fixed using CRISPR-Cas9.
205
For instance, renowned Harvard scientist, David
Sinclair, exclaimed that scientists can use CRISPR to excise a defective gene
that causes Huntington’s diseasea fatal brain diseasefrom the germline
“before we generate your child.”
206
Thus, the fungible product would be a de-
fective Huntington’s disease germline modification.

manufacturers when the plaintiffs DES dosage was a set quantity. See 733 P.2d 507, 51213 (Wash.

single letter. See Gallagher, supra note 81. Scientists predict this will decrease the likelihood of unin-
tentional edits in the germline since this base edit will prevent diseases caused by a single mutation.

Market share liability requires that the harm be attributable to any one of
the products provided by the industry.
208
For this reason, California courts have
extended market share liability to defective vaccine formulas, but not to negli-
gent administration of vaccines.
209
A CRISPR-Cas9 germline modification pro-
cedure to treat a specific disease may be similar enough to a defective vaccine
for courts to apply market share liability.
210
Whether or not harm will result from
flawed CRISPR-Cas9 applications and/or faulty genetic testing, or from the dis-
ease alteration procedure itself, will ultimately determine if CRISPR-Cas9 is a
fungible product.

C. Tracing the Cause of Genetic Defects Across Generations
Off-target impacts of a specific genetic alteration may be obvious and
consistent across victims, similar in nature to defective vaccines.

proving that a genetic alteration caused cancer or a physical deformity may be
easier than connecting a DES pill to cancer.

genetic make-up is passed on to subsequent generations, a victim generations

Expert testimony
could probably point to the manipulated gene and statistical harm across simi-
larly altered people to prove causation.
215
Whereas DES plaintiffs are often
forced to rely on circumstantial evidence that a woman in their family took
DES while pregnant, which resulted in a mutated gene passed on to subsequent
generations that increased the risk for certain diseases, here the genetic altera-
tion can serve as proof of heritability.
216
For instance, children who underwent
genetic engineering to rid their germline of a defective gene that caused sickle-
cell anemia would continue to pass on that modified gene to subsequent gener-
ations.
217
Still, echoing the concerns of scientists everywhere, some off-target im-
pacts from germline modification may be unique to each individual’s genome
making it hard for plaintiffs to connect the side effects to a defective proce-
dure.
218
Additionally, an individual’s specific genome may interact differently
with the modified gene than in the majority of other users resulting in negative
health effects despite a perfectly executed modification process.
219
Genetic
companies are likely to argue, like DES manufacturers, that their connection to
a negative health defect is too attenuated to prove liability.

estimate the risk of off-target effects from CRISPR-Cas9 gene editing have proven to be inaccurate in
practice. See Begley, supra note 14. Dr. Joung, a gene editing researcher at Massachusetts General
Hospital, commented that these algorithms “miss a fair number” of off-target impacts and “they really
aren’t very good at predicting where there will be off-target effects.” See id.

effects, a plaintiff is unlikely to prove causation.
221
Hopefully, algorithms that
predict off-target effects and gene modification impact will become more pre-
cise, but consumers are probably willing to risk negative side-effects to avoid
passing on a deadly disease, such as Huntington’s disease or sickle cell ane-
mia, to their children.
222
D. Market Compensation for Genetic Defects
Compensating victims for a defective gene alteration proves challenging
because of the potential harm to generations of plaintiffs who inherit the defec-
tive gene sequence.
223
Courts will have to estimate not only the claimant’s pre-
sent harms and future medical bills, but also that of potential children suffering
from the genetic harm.
224
Until genetic modification of the germline undergoes
clinical trials, the scale of possible harm remains speculative.
225
Given the unique field of genetic alteration, gene companies are in the
best position to sustain liability without compromising consumer compensa-
tion for defective products.

industry in which companies are investing and expanding rapidly.

In such a risk-intensive

stemming from older companies may be a necessary pre-market cost to enter
the genetic engineering business.

Moreover, rather than allow a bankrupt genetic company to discharge its debts
to the detriment of a family who continues to suffer generations of health de-
fects, tort law can ensure that subsequent participants pay for that harm.
234
The
growing pains of this high-risk, high-reward industry will last for generations,
so pre-market costs ensure fairness to those who paved the way for others to
enter.
235
As noted earlier, the harm from a defective germline modification may be
consistent across victims leading to streamlined recovery or the off-target im-
pacts may be uniquely assessed according to each individual.
236
Regardless of
the impact, the repercussions of a faulty procedure can be passed to subsequent
generations resulting in massive medical costs.
237
Unlike the Court of Appeals
of New Yorks 1991 decision in Enright v. Eli Lilly and Company, which justi-
fied limiting the liability of DES defendants to the third generation so that com-
panies could stay in business, genetic companies are likely to stay in the lucra-
tive business and be able compensate for multiple generations of recovery.

ONCLUSION
When the stories of science fiction touch today’s reality, the legal and
health ramifications call for preparation. The exceptional implications of ge-
netically engineering children to be born without predispositions to genetic
diseases prove too beneficial not to be questioned. As companiesand na-
tionsbegin to tap into these new markets and sell germline engineering like
they would a prescription drug or vaccine, tort liability must adapt to the unu-
sual circumstances. Entire family lines are at stake from a defective germline
procedure. In order to ensure continued compensation and to incentivize con-
servative entrance into the field, courts and legislatures should adopt the DES-
created market share liability in the context of genetic alteration. Market share
liability is an incomparable method to spread costs for the generational harm
an invaluable industry may inflict onto the public.
Volvo to be held strictly liable for any accidents with their self-driving vehicles). Genetic companies
can learn from another industry entering the unchartered territory of widespread tort liability: manufac-
turers of self-driving cars. See id. Companies that want to commercialize self-driving cars face hurdles
from regulators worried about liability to the public. See id. As a result, they have taken matters into their
own hands and pressured regulators into licensing their cars by taking responsibility for accidents. See id.
Currently the U.S. does not have federal laws or regulations on researchers modifying the human
germline. See Barnett, supra note 19, at 57778. In fact, while the FDA has the authority to regulate
human subjects,gametes and embryos involved in human germline modification do not meet that
identification. See id. at 578. Once the embryos are inserted into a human, then the FDA can regulate
and prevent clinical trials. Id. By taking responsibility for defective procedures in an industry based on
market share liability, genetic companies may be able to further federal support for clinical trials.
