RESUMO
Molecular genetic analysis of polymorphic variants of serotonin receptor genes (HTR2C and HTR2A) was performed in 89 healthy medical students and regulatory and adaptive capacities were determined by cardiorespiratory synchronism. The relationship of serotonin receptor gene polymorphisms and the regulatory and adaptive capabilities of the body were revealed. The highly active *G allele and *G/*G genotype of the serotonin receptor HTR2C gene and the heterozygous *A/*G genotype of the serotonin receptor HTR2A gene are associated with "good" regulatory and adaptive capacities. The low-active *C allele of the serotonin receptor HTR2C gene is associated with "low" regulatory and adaptive capacities.

The regulatory and adaptive status was determined in 202 healthy subjects by the parameters of the cardiorespiratory synchronism probe. We performed molecular-genetic analysis of polymorphic variants of the main gene of serotonin biosynthesis, tryptophan hydroxylase TPH1 (A218C polymorphism) and TPH2 (G703T polymorphism), and serotonin receptors (HTR2C and HTR2A genes). The association of the regulatory and adaptive status of a subject with the polymorphism of serotonergic mediator system genes was revealed.
