Abstract

We investigated the HLA-DRB, and DQB polymorphism and haplotypes in RA subjects of Hungarian origin by PCR typing using sequence-specific primers. Molecular subtyping of HLA-DRB1*04 alleles in RA patients showed strongest association with highest relative risk with DRB1*0404. A significantly decreased frequency of DRB1*0403 was observed in patients compared to controls. A significant number of patients carried DR4 haplotypes on DQB1*0302 (54%) relative to DQB1*0301 which was present on 36% of the haplotypes. When compared to controls, the frequency was higher in the latter allele only. Few unique DRB-DQB haplotypes were observed in Hungarian RA patients. In spite of the fact, that the Hungarian population has been isolated linguistically over centuries, a considerable racial admixture has occurred following immigration and invasions, thus the present study confirms in Hungarian patients with RA, previous findings for RA and HLA in European countries.
