Abstract
Previous studies have demonstrated associations between human leucocyte antigen (HLA) and some types of ischaemic stroke. In the present study, we genotyped HLA-A,-B and -DRB1 alleles in 140 Iranian patients with history of ischaemic stroke and 140 age-/sex-matched healthy subjects. No significant difference has been found in the distribution of HLA-A and B alleles between cases and controls. The DRB1*16 allele was significantly over-represented in patient group compared with control group (Adjusted p value=0.048). Other HLA-DRB1 alleles were not associated with stroke risk. The HLA-B*35,B*52 genotype was significantly more prevalent among patients compared with controls (Adjusted p value=0.03, OR [95% CI]=9.3 [1.3, 407.2]). Several HLA haplotypes were associated with risk of stroke in the assessed population. The current study provides further evidences for participation of HLA in conferring risk of ischaemic stroke.
