Аннотация
A comprehensive population and medical-genetic study was carried out in ten districts and two cities in the Karachay-Cherkess Republic (Russia). As a result, 57 patients with phenylketonuria were revealed. PAH gene genotypes for 40 probands and their diseased and healthy relatives were determined. The mutation spectrum of the PAH gene in the Karachay-Cherkess Republic was investigated. The major mutation in this region is R261X with allelic frequency of 68.4%. We elaborated a convenient system for detection of six PAH gene mutations common in the Karachay-Cherkess Republic, with the total information content of the system being 89.9%. As a result of processing the clinical data, association of the diet and phenylalanine levels in the blood was verified. Genophenotypic analysis confirms the association of the residual activity of phenylalanine hydroxylase and the severity of the disease. It is shown that common mutation R261X is severe and that patients who are homozygous for this mutation have classical phenylketonuria (PKU).
