Molecular genetic analysis of the VNTR alleles at the phenylalanine hydroxylase (PAH) gene was carried out in seven Volga-Ural ethnic groups (Bashkirs, Tatars, Chuvashes, Maris, Mordovians, Udmurts, and Komis). The PCR fragments revealed included alleles of 380, 440, 470, 500, 530, 560, and 650 bp, containing 3, 5, 6, 7, 8, 9, and 12 repeat copies,(More)
The distribution of alleles and genotypes of vitamin D-binding protein (DBP) gene has been studied in patients with Chronic Obstructive Pulmonary Disease (COPD, n = 298) and healthy individuals (n = 237) from two ethnic groups (Tatars and Russians) living in Republic Bashkortostan. Statistically significant differences in the distribution of DBP gene(More)
Three diallelic polymorphisms of human Y chromosome (DYS287(Y Alupolymorphism, YAP), T/C transition at the RBF5locus (Tat), and G/A transition at the LLY22locus) were studied in eight ethnic populations of the Volga–Ural region, representing Turkic branch of the Altai (Bashkirs, Tatars, and Chuvashes) and Finno-Ugric branch of the Uralic linguistic family(More)
Chronic obstructive pulmonary disease is a multifactorial respiratory disorder. Members of the cytochrome P450 family catalyze the oxidative metabolism of exogenous chemicals and activate their substrates into reactive intermediates that may initiate lung injury. The aim of this study was to learn interethnic variation in frequency distribution patterns of(More)
The analysis of polymorphisms of genes CYP1A1 (2454A > G,-3798T> C); CYP1A2 (-163C > A,-2467delT); TPO (2173A > C, 769G > T); DIO2 (274A > G) in women from the oil organic synthesis plant and the control group with thyroid disease (autoimmune thyroiditis and nodular goiter) has been performed. Molecular genetic markers of predisposition to the development(More)
The hyperpolymorphism of minisatellite DNA hybridizing with DNA of bacteriophage M13 was analyzed in seven Turkic and Finno-Ugric populations from the Volga-Urals region. In total, hybridization revealed 80 BspRI genomic DNA fragments ranging in size from 1.7 to 10 kb; the average frequency of an individual fragment was 0.299 +/- 0.020. The average number(More)
The article presents results obtained in study of relationship between polymorph variants of CYP1A1 and CYP1A2 genes with reproductive and thyroid diseases risk in female workers of petrochemical industry, when compared with reference group females. Variants TD and DD of CYP1A2 gene appeared to be associated with nodes formation in uterus and breast in(More)
Mutations of CFTR were studied in patients with cystic fibrosis (CF) from Bashkortostan. In total, 15 mutations were observed and 51% of all mutant alleles identified. The most diagnostically significant mutations were delF508 (33.8%), 394delTT (3.52%), CFTRdele2,3(21kb) (1.41%), R334W (1.41%), 3849 + 10kbC → T (1.41%), and N1303K (1.41%). Mutations G542X,(More)
Genetic polymorphism of xenobiotic metabolizing enzymes responsible for individual susceptibility to different environmental factors was examined in a cohort of petrochemical workers occupationally exposed to adverse action of chemical compounds. Molecular genetic analysis of the I462V mutation in exon 7 of the CYP1A1gene demonstrated close similarity(More)
