Association of UBASH3A gene polymorphism and atopic dermatitis in the Chinese Han population

Genome-wide association studies have revealed a large number of genetic-risk loci for many autoimmune diseases. One clear finding emerging from the published genetic studies of autoimmunity is that different autoimmune diseases share susceptibility loci. Recent evidence has demonstrated that UBASH3A gene was associated with multiple autoimmune diseases. The aim of this study was to explore the association between UBASH3A single-nucleotide polymorphisms (SNPs) and atopic dermatitis (AD) in a Chinese Han population. In total, three UBASH3A SNPs (rs11203203, rs3788013 and rs1893592) were genotyped using TaqMan genotyping assays in a Chinese Han population (1012 cases and 1362 controls). Among these SNPs, we selected the SNP rs1893592 with association values of P
