Epidemiology of monogenic hereditary diseases in Rostov oblast: Population dynamic factors determining the differentiation of the load of hereditary diseases in eight districts

摘要

Analysis of the diversity of monogenic hereditary diseases in eight raions (districts) of Rostov oblast (region) of Russia (Tsimlyansk, Volgodonskoi, Tselina, Egorlykskaya, Millerovo, Tarasovskaya, Rodionovo-Nesvetaiskaya, and Matveevo-Kurgan raions) has been summarized. The total sample size was 320925 subjects. The spectrum of hereditary diseases detected in the eight districts comprises 187 diseases, including 99 autosomal dominant (AD), 72 autosomal recessive (AR), and 16 X-linked diseases. The mean prevalence rate of each disease in the total population has been calculated. Accumulation of individual diseases in different regions of Rostov oblast has been calculated; the disease accumulation has been compared with that in some populations of Russia examined earlier. Cluster analysis using the data on the frequencies of genes of hereditary diseases has shown the gene geographic position of the Rostov oblast population among the following ethnic populations of Russia: Russians (Kostroma, Kirov, and Rostov oblasts and Krasnodar krai), Chuvashes (Chuvashia), Adygeans (Adygea), Maris (Marii El), and Udmurts (Udmurtia).
