It should be noted that psychogenetic research in sport until now has been limited to studies involving power, endurance, combat, and game sports athletes only, with a focus on stress resilience (COMT rs4680), reaction time (APOE ε2/ε3/ε4, KIF27 rs10125715, APC rs518013, TMEM229A rs7783359, LRRN3 rs80054135), memory (APOE ε3/ε4, BDNF rs6265), sensation seeking (DRD3 rs167771, DRD4 rs1800955), anxiety (ACE I/D, COMT rs4680, MAOA VNTR polymorphism), aggressiveness (MAOA VNTR polymorphism), and motivation (MAOA VNTR polymorphism) [44,45,46]. This evidence concerns the gene ACE and Anxiety.
