Polymorphisms of xenobiotic biotransformation genes and their role in individualization of pharmacological therapy and support of humans after heavy psychophysical loading

We analyzed the frequency distribution of CYP1A1, EPHX1, GSTM1, GSTP1, GSTT1 genes polymorphisms in 111 persons exposed to high physical and mental stress (elite athletes). Qualifications of sportsmen ranged from candidates for master of sports to world-class athlete. Comparative analysis revealed significant differences between the main group and the comparison group in the frequency of GSTM1, GSTT1, CYP1A1 genotypes, and a tendency to a predominance of genotype GSTP1 Val / Val in the main group.
