| Abstract: | Medical-genetic study was carried out in the population of Khorezm province (population size above 200 000 persons). Hereditary pathology was ascertained among families having two or more members affected with chronic non-infectious diseases. 155 families with 348 members affected with hereditary diseases were registered. The most frequent were autosomal recessive diseases (55 nosological forms in 104 families with 271 affected), then followed the autosomal dominant conditions (10 nosological forms in 21 families with 53 affected). The less frequent was X-linked recessive pathology (6 forms in 12 families with 20 affected). The main part of cases of autosomal recessive pathology were found in separate families and were not observed during previous medical-genetic studies in Uzbekistan. Three autosomal recessive conditions are probably new forms of hereditary pathology. The important role of assortative matings in manifestation of rare autosomal recessive genes in Uzbek population is discussed. |
