Aim. The purpose of this study was to compare the difference in distribution of the genetic polymorphism within the D-loop region of mtDNA in controls and judoists, and to investigate the relationship between this polymorphism and iron parameters in both groups.
Methods. A total of 117 male subjects including 57 controls and 60 judoists were selected for this study. The C to A polymorphism of mtDNA was analyzed by PCR-KpnI restriction digestion method, and biochemical parameters measured by autoanalyzer.
Results. The allele distribution of this polymorphism was 75.9% and 24.1% for C and A alleles, respectively, and similar between controls and judoists, respectively. With respect to iron parameters, this polymorphism was not significantly associated with any iron parameters studied in our subjects(P>0.05)
Conclusion. In conclusion, our results suggest that this genetic polymorphism of D-loop region in mtDNA might not be useful as a genetic marker influencing iron metabolism in our subjects. Further studies using large sample size and other candidate genes will be needed
