Ballet dancers' emotional and behavioral characteristics vary, even under identical stress conditions. This study aimed to investigate the association between the pain candidate genes 5-HTTLPR and COMT and anxiety in Japanese ballet dancers. Participants were 18 youth elite ballet students with professional aspirations (Y-Elite) and 16 dancers in a professional ballet company (Pro). We administered psychological questionnaires, the State-Trait Anxiety Inventory (STAI) and Brunel Mood Scale (BRUMS), to participants under the following four different stress conditions: standard practice day, cast decision day, rehearsal day, and one week before competition day. In addition, the genotypes of 5-HTTLPR and COMT Val158Met were examined. The distribution of 5-HTTLPR was not different between Y-Elite and Pro dancers, although one of the COMT genotypes was different. Y-Elite dancers had higher trait anxiety scores than Pro dancers for these genotypes before competition (ps < 0.03), although no significant association was observed between both genotypes and scores on the STAI across conditions. Their moods were significantly different through the four conditions (<i>p</i> < 0.004). Pro dancers' moods were also more stable than those of the Y-Elite dancers in the presence of pain. The results indicate that 5-HTTLPR and COMT play a crucial role in dancers' anxiety and mood during pain (ps < 0.05). Pro dancers are probably predicted by their lower neuroticism and mood scores and their better adaptation to stress than Y-Elite dancers. The 5-HTTLPR and COMT genes may be influencing the sensitivity to the environment.
