Abstract
This article uses the experiences of professional soccer player Abdelhak ‘Appie’ Nouri, who suffered a cardiac arrhythmia at 20 years of age during a pre-season friendly in 2017, as the stepping off point for examining the use and regulation of genetic testing in sport and the human rights implications of genetic testing child athletes for the purposes of talent identification and performance enhancement. The authors identify recent trends in the use of genetic testing in sport, outline the legal and policy framework that regulates genetic testing in Australia, and consider human rights issues that arise in relation to a child’s decision to undertake or withhold consent for testing.
In what is one of the most high-profile career-ending events in professional soccer around the world, on 8 July 2017 Eredivisie club Ajax midfielder Abdelhak ‘Appie’ Nouri suffered a cardiac arrhythmia in the 72nd minute of a preseason friendly in Austria against Werder Bremen. His ‘heart defect’ was known to the club. 1 Despite being revived on the pitch, ‘inadequate’ on-field care resulted in serious and permanent brain injury. 2 For two years and nine months following the injury, Nouri was in a state of low consciousness. He recovered a degree of consciousness in 2020 but remains highly dependent for his daily care. Nouri will not play professional soccer again.
Legal commentary to date on Nouri’s career-ending injury has focused on whether the Ajax club doctor adhered to medical guidelines in their on-pitch medical treatment: there was a five-minute delay between Nouri losing consciousness and the administration of CPR/defibrillators. However, while Ajax initially contested the negligence action commenced against the club in the Royal Dutch Football Association’s Arbitration Panel – although paying Nouri’s contracted salary in full and agreeing to pay his medical care for life – they later admitted liability. 3 With Nouri’s contract formally cancelled from 1 July 2020, speculation abounds that a final financial settlement, estimated to be in excess of AUD 8 million, will be reached in the coming months. 4 Yet, regardless of the impending resolution of this matter, as a high-profile professional athlete with a cardiac abnormality, Nouri’s experiences provide a useful stepping off point to reflect upon the use and regulation of genetic testing in sport.
Genetic testing examines one’s DNA to gain an understanding of individual traits and characteristics including athleticism, susceptibility to diseases such as heart disease and different types of cancers, and predisposition to disabilities and mental illness. This article will focus on the uses of genetic testing in sport to elicit information about predisposition to illness and disease, injury prevention, performance enhancement, and talent identification. It will discuss the perceived benefits of genetic testing in these areas before identifying the legal and policy framework that testing occurs within, and the distinct ethical considerations for child athletes who, like Nouri, rise up through the ranks of youth sport. The article concludes that the human rights implications of children consenting (or refusing to consent) to genetic testing should be addressed in the regulatory framework.
Uses of genetic testing in sport
In 2014, the year that Nouri was named as one of the 40 best youth players in the world, a routine ultrasound of the heart detected a cardiac abnormality. Nouri was 17 years old at the time, an outstanding player at the Ajax youth development academy. According to news reports, the Dutch Football Association informed Ajax and Nouri of this result but determined that the condition was ‘harmless’. 5
It is unclear whether a heart defect caused Nouri’s collapse on the pitch during the Werder Bremen game. However, most sudden cardiac arrests that occur in younger athletes aged under 35 years old, during physical exertion, are attributed to inherited or congenital disorders of the heart that predispose the athlete to cardiac arrhythmias. 6 While the usefulness of genetic testing for Nouri’s health back in 2014 is speculation, genetic testing can in some instances supplement medical examinations like echocardiograms to generate key insights into an individual’s susceptibility to injury and disease. It can confirm certain conditions that affect the heart, such as Marfan Syndrome that has been linked to an aortic aneurysm in tall athletes like basketball players and volleyball players.
Genetic testing of athletes is perceived to be particularly beneficial in high-impact sports that involve repetitive blows to the head such as boxing and rugby. Genetic variations like apolipoprotein-E-4 (APOE4) make individuals more susceptible to brain damage from head injuries, and polymorphism in the APOE4 gene may predict Alzheimer’s disease, and there is evidence of testing for this gene in the Australian boxing community. 7 Genetic testing can also be useful for general injury prevention and recovery, high priority areas for athletes, performance staff, and medical personnel. Research into genetic variation and its impact on tendon and ligament injuries has proven particularly fruitful, with a genetic contribution identified in certain musculoskeletal soft tissue injuries involving, for example, the Achilles tendon in the heel, the rotator cuff tendons in the shoulder, and the cruciate ligaments in the knee. 8 The Athlome Project Consortium was established in 2015 to aid, among other things, the identification of reliable genetic tests for exercise prescription and injury prevention. 9 While genetic testing for injury prevention remains uncommon, an English Premier League football club was reported to be analysing players’ genetic profiles for markers for injury in 2011, and in 2016 Barcelona Football Club announced it would be analysing the genetic markers of its players to identify those who may be predisposed to injury or need a longer recovery period. 10 The ability to predict injuries could prove significant as research into risk marker genes continues.
More controversially, genetic testing is also perceived to hold value for performance enhancement and talent identification. At the more innocuous end of the scale, testing can offer insights into the nutritional requirements of high-performing athletes. In 2016, Ajax announced that they were using genetic testing to tailor individual nutrition programs for their athletes. 11 At the more extreme end of the scale, gene manipulation known as ‘gene doping’ may offer athletes a competitive edge by improving their athletic abilities and performance. This involves using artificial means to enhance an individual’s genetic makeup by adding certain genes associated with athletic performance (or subtracting genes that are not so characterised) to the individual’s genetic makeup. While gene therapy has proven effective in treating some specific diseases, gene doping is expressly prohibited by the World Anti-Doping Association (WADA), as discussed in the next section.
Gene doping is an extreme application of genotyping – the process of determining differences in the genetic make-up of an individual by examining their DNA sequence. For over 50 years, sports scientists have used genotyping to try and predict future sports stars by identifying exercise-related genes. Genes are estimated to control up to 50 per cent of one’s athletic ability, such as the alpha-actinin-3 (ACTN3) gene that is prevalent in elite sprinters. 12 A recent study of sub-elite Australian Rules football players confirmed that a number of physiological mechanisms of skill and talent for sport-specific skills are explained by the expression of a specific number of genes. 13 However, despite growing knowledge of genes linked to sporting performance, scientists warn that genetics offer only an estimation of future performance and are not an exact prediction. 14
Nevertheless, the use of DNA and gene mapping as a predictive tool and recruitment strategy for athletes continues to develop. Uzbekistan indicated that they would use genetic testing as a means to identify future Olympians from 2015, with children as young as 10 taking part. 15 Similarly, China has confirmed that they would be using genome sequencing as a means to recruit athletes for the 2022 Winter Olympics. 16 These strategies are not currently used in Australia, with the Chief Medical Officer at the Australian Institute of Sport (AIS), David Hughes, confirming that AIS does not support the genetic profiling of its athletes, particularly child athletes. 17 However, other Australian officials have previously been supportive of the possibility of routine genetic testing as part of talent identification strategies in future. 18 Research on genetic testing in sports continues to develop at a rapid pace, and is likely to continue in Australia. DNA biobanks have recently been established containing biological specimens and genetic data from thousands of elite athletes around the world. 19
Genetic testing in sport – whether for identification of disease, injury prevention and recovery, performance enhancement or talent identification – might be uncommon at present but it does occur in pockets, and it appears to have the potential to secure benefits to athletes and sporting organisations. It is anticipated that such benefits will increase with scientific advancements in future. It is thus timely to consider the regulatory framework within which such testing in sport occurs.
Regulatory framework
Formal regulation of genetic testing in sport is minimal. To date, international regulations have primarily focused on gene doping. As discussed, the use of gene doping was officially prohibited under the World Anti-Doping Code in 2004, which defined such methods as involving ‘the non-therapeutic use of genes, genetic elements and/or cells that have the capacity to enhance athletic performance.’ 20 No violations of this prohibition have been proven. However, anecdotal evidence of gene doping exists: in 2006 German athletics coach Thomas Springstein was revealed to have attempted to purchase Repoxygen – a substance used in gene therapy to treat patients with anaemia that induces expression of the erythropoietin gene – during an investigation into his supply of banned substances to athletes in 2003, and in 2008, a Chinese genetics laboratory reportedly offered gene-based manipulations before the Beijing Olympic Games. 21 Nevertheless, the lack of Doping Code violations is perhaps unsurprising given that an effective test for gene doping was only reported to WADA in late 2018. 22 Prior to this test, speculation abounded that WADA would require all Olympic athletes to submit copies of their full genetic code so that they would be able to determine if gene doping or gene editing has taken place. 23 This intrusive requirement never eventuated, and it is unclear whether it will be adopted in future.
In Australia, genetic testing in sport is subject to a blanket prohibition against discrimination based on disability 24 and policy guidance from interested bodies such as the AIS and the Human Genetics Society of Australasia (HGSA). The AIS discourage genetic testing for athletic performance or improvement including gene doping, sport selection, and talent identification. Where there is adequate informed consent, genetic testing for the purposes of injury prevention is acceptable. 25 Conversely, the HGSA’s Position Statement indicates concern for direct-to-consumer genetic tests and their scientific accuracy, and cautions against using test results to limit the opportunities of individuals who possess the ‘wrong’ genotypes. The HGSA does not object to using genetic testing for talent identification and training purposes, but states that a ‘simplistic and overly-deterministic approach to genetic testing’ should be avoided, ‘particularly when applied to children.’ 26
Outside of Australia, some jurisdictions have laws that directly address permissible uses of genetic testing in sport. Article 12 of the Council of Europe’s Convention on Human Rights and Biomedicine,
27
that covers bioethics, explicitly states that: Tests which are predictive of genetic diseases or which serve either to identify the subject as a carrier of a gene responsible for a disease or to detect a genetic predisposition or susceptibility to a disease may be performed only for health purposes or for scientific research linked to health purposes, and subject to appropriate genetic counselling.
This is limited to testing for diseases, which suggests that the use of testing for predictive purposes or talent recruitment would not be permissible unless it also served a specific health purpose. In such instances, the individual would need to receive their test results in conjunction with appropriate genetic counselling to avoid a breach of Article 12. Counselling might cover issues such as the nature of the relevant genetic disorder or condition, the relationship between the genetic markers and the likelihood that the identified condition will develop, or the risks of the misuse of genetic information.
Other jurisdictions, such as Canada, prohibit employers (including sporting organisations) from requiring genetic testing or the results of such tests, and from refusing to provide services on the basis of genetic tests. 28 In addition, the United States (US) prohibits the use of genetic information to discriminate against an individual in employment, including when making hiring or termination decisions. 29 While no sport case has arisen under the US law, it likely encompasses a prohibition against mandatory genetic testing for predictive purposes in an employment context. 30 As such, circumstances such as the case of NBA player Eddy Curry, who was required by the Chicago Bulls to take a DNA test after he experienced some heart discomfort during the 2005 season (and prior to the introduction of the relevant US law) before they would enter into contract renegotiations, would not be permitted. 31
While such laws go some way towards redressing genetic discrimination, the legal concerns that arise with genetic testing in sport go beyond the general permissibility or desirability of testing in different contexts and also encompass human rights issues, as will now be explored in the context of child athletes.
Human rights concerns and child athletes
While Australia does not have a national human rights framework, it has signed and ratified a number of international Conventions that seek to protect human rights, including the UN Convention on the Rights of the Child (CRC). 32 The CRC is particularly instructive in identifying the human rights implications of genetic testing on child athletes as it traverses participatory decision-making as a human right and the right of children to consent, or refuse to consent, to medical treatment. While mandated genetic testing in youth sport is rare (or at least, rarely reported), the Uzbekistan experience of testing children as young as 10 for future Olympics suggests that a child might, at some stage in their blossoming career, be encouraged to undergo testing. To the extent that such a request was for the purpose of gauging or confirming their future sporting ability, it could amount to a violation of the child’s rights under the CRC, regardless of whether a parent or guardian approved of such testing.
The CRC affords children under the age of 18 years a voice in the decisions that affect them, including those that might curtail their future opportunities. 33 Article 5 recognises the ‘evolving capacities’ of children, and Article 12 – that outlines the child’s right to participate in decision-making – states their views should be given due weight in accordance with their age and maturity. Nouri was 17 years old when his cardiac abnormality was first detected. If he had been requested to undertake further tests by Ajax, he would have been entitled to make a decision to comply or refuse, and given his age it is likely that this decision would be legally enforceable, regardless of the views of his parents, agent, the club, or others. However, younger children, such as those who are considered for youth academy programs typically from the age of nine, might be given the opportunity to express their views but their views are unlikely to carry the same weight as older children.
Given the potential for non-selection on the basis of ‘unfavourable’ genetic test results, all children should be given the opportunity to express their views freely once they are ‘capable of forming their own views’. 34 Moreover, their views should carry due weight in line with the child’s age and level of maturity. It has long been recognised in international law that minors have the capacity to consent to medical treatment provided their decision is valid, informed and voluntarily made. As the Committee on the Rights of the Child has stated, in health care ‘[c]hildren, including young children, should be included in decision-making processes, in a manner consistent with their evolving capacities.’ 35 Informed consent is necessary because decision-making is often a three-way process between the child, their parents and the healthcare professional, and each party may have competing objectives. 36 A child could have ‘little space’ to freely articulate their views during the consultation, inhibiting them from understanding what is being said or recommended. 37 The decision-making processes for a child asked to undertake genetic testing are likely to be even more complex and crowded, with the views of individuals such as their agents, managers, sports selectors, coaches, or lawyers, to be taken into consideration. The regulatory framework on genetic testing should support a child’s right to express their views freely, and those views should carry due weight.
The right to consent to medical testing also includes the corollary right to withhold consent. 38 Exercising the right to refuse a genetic test is likely to be fraught, particularly in circumstances where a lucrative sporting contract lies in the balance. The ready availability of direct-to-consumer genetic tests which claim to be able to identify athletic ability means that a parent, guardian, coach, or selector could order a kit online and encourage the child to take a test at home (or coerce them to do so), without the child receiving genetic counselling as part of the process. The regulatory framework should explicitly address this possibility and provide guidance on when it may be appropriate to require direct-to-consumer genetic testing as part of, for example, contract negotiation. The position adopted in the Australian Medical Association’s Position Statement on Genetic Testing, that ‘children should not normally undergo predictive genetic testing until they have reached the age of consent and so are able to request the test on their own behalf’, 39 should also be endorsed.
Finally, even when a child’s free and informed consent to genetic testing is secured, privacy concerns remain around the management of their genetic information. There might be uncertainty around how the genetic information can be used, how long it is stored for and who will have access to it (such as insurance bodies and possibly even law enforcement agencies). Concerns are heightened by the fact that it is common for athletes to sign a waiver of medical confidentiality when entering a professional sports program and privacy breaches can ruin an athlete’s market value. In addition, while the AIS and many private sector sports organisations fall within the jurisdiction of the Privacy Act 1988 (Cth) they are not health service providers and thus, the results of genetic tests of contracted athletes would likely be considered part of ‘employee records’ and not health information protected by the Act.
40
This means that sensitive information, including a player’s entire medical history and potentially their family members’ information, could be legally made available to third parties, such as their employers or agents (or future employers).
41
This raises clear concerns for the child’s right to privacy, as enshrined in Article 16(1) of the CRC, which states that: No child shall be subjected to arbitrary or unlawful interference with his or her privacy, family, home or correspondence, nor to unlawful attacks on his or her honour and reputation.
The privacy implications of genetic testing should be explained to all children in clear and accessible language as appropriate to their age, so that it factors in their decision-making. When an athlete, including a child athlete, consents to genetic testing, confidentiality clauses should be used to protect their privacy and manage the risk of unauthorised dissemination of test results. Further elaboration on specific privacy protections and guarantees are also required to ensure compliance with the CRC.
Conclusion
Genetic testing in sport can arguably improve health and performance outcomes but it occurs with little regulatory oversight. In circumstances where testing is becoming increasingly advanced and direct-to-consumer tests more widespread, the time is ripe for more detailed legal and policy guidance in this area.
We do not know the extent to which Abdelhak Nouri’s pre-existing cardiac condition contributed to his collapse on the pitch on 8 July 2017. It is also unclear whether genetic testing would have prevented his injury. However, respect for the health of promising athletes like Nouri who progress through the ranks of youth sport and may carry genetic abnormalities, requires attentiveness to the potential benefits of testing but also human rights concerns in the legal and policy framework.
