Association of polymorphous alleles of class II HLA genes with Graves' disease (GD) in Tuvinian population

Abstract

Aim: to consider association of polymorphous alleles of class II HLA genes with Graves’ disease (GD) in Tuvinian population. Methods. HLAgenotyping was accomplished in 40 GD patients and 164 volunteers randomly selected in Tuvinian population (native Siberian population, Mongoloids). GD was diagnosed accordind to the clinical and laboratory criteria. HLAgenotyping for 14 DRB1 alleles, 8 DQA1 alleles and 13 DQB1 alleles was performed by polymerase chain reaction sequencespecific primers (DNATechnology, Russia). Statistical analysis was performed using the Excoffer, Schneider and Kuffer package. RR have been calculated using Woolf method. Results. We found the HLAmarkers of predisposition to GD in Tuvinians: HLA DQA1*0501( RR = 1.76; p 0.05) and DQB1*0301 (RR = 1.44; p 0.05). Analysis of the HLA haplotypes showed, that DRB1*13DQA1*0501 DQB1*0301 was associated with an increased risk of GD (RR = 3.53). The protective were DRB1*0302 (RR = 0.19) and haplotype DRB1*04DQA1*0301DQB1*0302 (RR = 0.02). Conclusions. This molecular genetic study has been shown that HLA DQA1*0501, DQB1*0301 and haplotype DRB1*13DQA1*0501DQB1*0301 associated with Graves’ disease in Tuvinian population.
