| Abstract: | Medical-genetic study in some populations of Khorezm (about 200,000) and Samarkand (about 56,000) provinces was performed with the view of identification of all family cases of deafness and deaf-mutism. 53 families with 140 affected patients were registered, in total. 8 nozological forms were found in this study, the most frequent being autosomal-recessive ones (6 nozological forms, 48 families, 122 patients). The autosomal-dominant forms were represented by 2 nozological forms (5 families with 18 patients). The reason for predominance of autosomal-recessive deafness in Uzbek population is discussed. |
