Özet: We aimed to determine the genotype and allele distributions of the serotonin transporter protein gene (SLC6A4) promoter L/S polymorphism in volleyball players and compare it with the previous studies in the literature in this study. For this purpose, 21 volleyball players participated in our study. Genotyping was performed by PCR after DNAs were isolated from buccal cells. The literature review has been done in Google Scholar and PUBMED databases with the keywords and combinations of “sports, athletes, genetics, SLC6A4, sports genetics, polymorphism”. In our cohort, LL, LS and SS genotypes were found in numbers and percentages as 10 (48%), 7 (33%) and 4 (19%), respectively. The respective L and S allele count numbers and percentages were 27 (64%) and 15 (36%). 9 different studies matched our criteria and compared with our findings with literature review. As a result, the low percentage of SS genotype in terms of genotype distribution was common with the previous studies and our findings. The S allele percentage was higher than our results just in one research. Recent studies have shown that the “S” allele is associated with anxiety. Our study was the first report to show that the LL genotype and L allele in volleyball players are higher than the SS genotype and S allele.
