Association of type 1 diabetes mellitus (DM1) with polymorphous alleles of class II HLA genes in Yakutian and Russian populations

https://doi.org/10.14341/2072-0351-5448

Abstract

Materials and methods. HLA genotyping was accomplished in 51 DM1 patients and 51 volunteers randomly selected from the indigenous populationof Yakutia (Yakuts in three successive generations). Another 205 DM1 patients and 300 healthy subjects comprised random samples of patients andcontrols respectively from residents of Moscow and Moscow region.
Results.
HLA DRB1*17(03) allele proved to be the strongest one predisposing to DM1 in the Yakutian population (relative risk, RR=8,47) andDQB1*0304 in the Moscow population (RR=8,94). The presence of DRB1*04, DRB1*17(03), DQA1*0301, DQB1*0201, and DQB1*0302 accountedfor RR >2 in both populations. Only two alleles, DRB1*04 and DRB17(03), in the Yakutian population and five of the six (DRB1*04,DRB1*17(03), DQA1*(0301), DQB1*0302, and DQB1*0304) in the Moscow one were closely associated with DM1 (RR >4). DRB1*09, DRB1*11,DQB1*13, DQB1*0602/8 in Yakutian and DRB1*11, DRB1*13, DQA1*0103, DQB1*0301, DQB1*0602/8 in Moscow populations had the highestprotective potential (RR<2). The Yakuts appear to show a broader spectrum of protective alleles. However, the study gave no definitive evidence ofthe protective role of widespread DQB1*0602/8 and DRB1*15 alleles inherent in both Russian and Finnish populations.
Conclusion.
These molecular genetic data can be of use for medicogenetic consultation to estimate the risk of DM1 in the Yakutian population.
