Genotyping of TRPV1 and TRPA1 genes encoding thermoreceptors in the populations of the Altai-Sayan region and the Far East was conducted. The sample consisted of 15 populations comprising 1482 individuals. The analysis of TRPV1 rs222747 demonstrated that the frequency of M315I was closest to East Asian populations only in Nanais and Koryaks (56 and 64%, respectively). Siberian Tatars, Yakuts, and Evenks were closest to European populations. All populations of the Altai-Sayan region reported an intermediate position between the Caucasoids and the Eastern Mongoloids on the basis of the frequency of M315I. No deviations from the Hardy–Weinberg distribution were observed. The observed heterozygosity exceeded the expected one in eight populations. The analysis of TRPA1 rs13268757 revealed that Chukchi, Yukaghir, Koryak, Tuvinian, Southern Altaian, and Telengit populations were closest to the East Asian populations on the basis of the frequency of R3C substitution (3–7%). At the same time, populations of Siberian Tatars, Nanais, Evenks, Yakuts, Shorians, Khakases, and Kazakhs were intermediate between the Caucasoids (18–23%) and the Mongoloids from East Asia (3–7%) on the basis of the frequency of this polymorphism. A deviation from the Hardy–Weinberg distribution was detected only in the Yukaghir population. The observed heterozygosity was higher than the expected one in nine populations. A trans-association of TRPA1 and TRPV1 gene polymorphisms was carried out in 14 populations via regression analysis. A negative correlation of–0.545 was determined, the number of degrees of freedom (df) was 13, and the P-value was 0.048. The data obtained indicate that the analyzed polymorphisms are correlated, which confirms an earlier conclusion of the TRPA1-dependent inhibition of TRPV1 function. The results may evidence in the co-evolution of analyzed genes.
