Investigating a Variant in the Vitamin D Receptor Gene in Ahvaz Male and Female Athletes Compared to the Control Group with Normal Body Mass

Abstract

Background: Typically 20-80% of changes in sports performance traits are related to genetic factors. To date, more than 200 genes related to sports performance have been identified. The VDR (Vitamin D receptor) gene can play an important role in cell proliferation, differentiation, and contraction process. The aim of this study is to investigate a variant of the VDR gene in athletes as a genetic marker in determining sports talent. Methods: In this research, 100 professional athletes in 2 groups, men and women and 100 healthy non-athletes with normal BMI were included in the study as a control group. After obtaining informed consent, blood was drawn to determine the genotype of rs10735810 polymorphism or FokI locus by ARMS-PCR method. Data analysis was done with GraphPad Prism 6 software and the Chi-squared test. Findings: The number of people with the F/F genotype in the athletes’ group was 23% and in the control group was 65%, as well as the people with the F/f genotype in the athletes’ group was 64% and in the control group was 20%. The number of people with the f/f genotype in two the athletes group was 13% and the control group was 15%. Also, no significant difference was observed from the comparison of genotypic frequency in the two groups of female and male athletes compared to each other. Conclusion: This study showed that the effect of the f allele is only in the heterozygous state which indicates the gender-independent effect of this polymorphism in the population.
