[Medical genetics study of the population of Kostroma Province. II. The diversity of hereditary pathology in 5 districts of the province]

Abstract

The diversity of hereditary pathology in 5 regions of Kostroma district was studied. 32 nosological forms of autosomal dominant, 30 autosomal recessive and 7 X-linked recessive disorders were found. The most frequent autosomal dominant disorders were: neurofibromatosis, pigmentary degeneration of retina, hypochondroplasia, ichtiosis, idiopathic scoliosis. The most frequent among the autosomal recessive disorders were: oligophrenia, pigmentary degeneration of retina, muscular atrophy of juvenile Kugelberg--Welander type, congenital cataract. The most frequent X-linked disorders were: muscular Duchenne type dystrophy and hemophilia A. Analysis of mutant gene distribution over the territory by the study of birthplaces of probands and their parents was carried out.
