Numerous studies have identified over 185 genetic markers associated with sports performance, highlighting the complex relationship between genetics and athletic ability [7]. Genetic variations can influence muscle composition, metabolism, and response to training, making them targets for both legal gene therapy and illicit gene doping [10]. The literature underscores that while genetic testing may offer benefits in screening and injury prevention, its misuse for performance enhancement poses significant ethical and legal risks [9,11].

2.2.2. Emergence of Gene Editing and Doping

Gene editing technologies, especially CRISPR-Cas9, have accelerated the potential for gene doping-defined as the non-therapeutic use of genetic modifications to enhance performance [8]. WADA officially banned gene editing for performance enhancement in 2018, but detection remains a major challenge due to the subtlety of genetic changes compared to traditional doping substances [12]. Prime editing, a recent innovation, further increases the precision and scope of possible genetic alterations, intensifying concerns about undetectable enhancement[8].

2.2.3. Detection and Regulation

Efforts to detect gene doping have advanced, with recent breakthroughs allowing for the identification of CRISPR-Cas9 enzymes in biological samples [12]. However, the capacity to comprehensively screen for all types of gene editing remains limited [9,13]. Regulatory bodies, including WADA and international bioethics committees, are actively developing guidelines to address these gaps, often in collaboration with pharmaceutical and life sciences sectors [12].

2.2.4. Ethical and Legal Challenges

The literature consistently highlights profound ethical issues, including the risk of genetic discrimination, violation of human rights, and the creation of inequities between athletes with and without access to gene editing technologies [10]. There is a strong consensus that integrating ethical considerations into policy and practice is essential to uphold fairness and protect athlete welfare. The permanence of germline modifications and their impact on future generations further complicate the ethical landscape [10].

2.2.5. Summary of Key Themes

Table 2 categorizes the major themes emerging from the literature on genetic editing in sports. These include genetic screening for injury prevention, gene doping and its detection challenges, regulatory frameworks such as WADA’s prohibitions, ethical issues surrounding fairness and discrimination, and technological advancements like CRISPR and prime editing. The thematic organization aids in understanding the complex interplay of scientific, ethical, and legal factors.
