The level of T174M polymorphism of the angiotensinogen gene (AGT) was studi
ed for the first time in Siberian populations. The frequency of allele M wa
s found to be 7% in Russians, 6% in Tuvinians, and 4% in Buryats. In the Mo
ngoloid population of Siberia (Tuvinians and Buryats), the genotypic freque
ncies deviated from Hardy-Weinberg equilibrium (P < 0.05). The studied poly
morphism of the AGT gene determined in Siberian populations was compared wi
th that of other ethnic groups in the world population, and genetic distinc
tions were estimated. Only the Buryat population was found to differ signif
icantly from the French, English, and Chinese in the frequency of allele M.
No association between the T174M polymorphism of the AGT gene and patholog
ical pregnancy (gestosis) was revealed in Buryat women.
