Here we present the data obtained during medical genetic examination of the population of five districts of Bashkortostan Republic (Burzyanskii, Baimakskii, Abzelilovskii, Salavatskii, and Arkhangelskii) populated with 168050 persons including 135748 Bashkirs. The study involved all the population of the districts including each ethnic group and was conducted according to standard protocol developed in the Laboratory of Genetic Epidemiology, Medical Genetic Research Center, Russian Academy of Medical Sciences. Based on segregation analysis, the values of prevalence rates of the major types of Mendelian pathology (AD, AR, and X-linked diseases) was calculated in five regions of the Republic as well as for Bashkirs alone. Significant differences in the prevalence rates of AD and AR pathologies between individual districts, in particular upon division in rural and urban population, was observed. The prevalence rates comparison of monogenic hereditary pathology among Bashkirs compared to other previously examined populations have shown that the patterns of the hereditary disease load in the inspected districts of Bashkortostan were similar to that observed in the population of some districts in Udmurtia, Marii El and Chuvashiya. Russian European populations have shown significantly lower load of hereditary diseases. Correlation analysis of local inbreeding, endogamy and prevalence rates of AD and AR pathologies has shown that development of hereditary diseases load is significantly affected by gene drift.
