Association of and With Moyamoya Disease in the Chinese Han Population
Overview
Affiliations
Objective: An HLA imputation was conducted to explore the relationship between HLA and patients with moyamoya disease (MMD) in the Chinese Han population.
Methods: In this study, we performed an association analysis of the major histocompatibility complex region in 2,786 individuals of Chinese Han ancestry (2,031 controls and 755 patients with MMD), through a widely used HLA imputation method.
Results: We identified that the variant rs3129731 (odds ratio [OR] = 1.79, = 3.69 × 10) located between the and is a major genetic risk factor for MMD. In addition to this variant, found in the conditional association analysis, we also detected another independent signal, rs1071817 (OR = 0.62, = 1.20 × 10), in HLA-B.
Conclusions: Our research suggests that the genetic polymorphism of and could be a genetic predisposing factor for MMD in Chinese Han. This may provide some evidence for further HLA-related studies of patients with MMD of Chinese Han ethnicity and indicates that MMD is an immune-related disease.
