Abstract

Immunoglobulin A nephropathy (IgAN) is a form of chronic glomerulonephritis of unknown etiology and pathogenesis. Immunogenetic studies have not conclusively indicated that human leukocyte antigen (HLA) is involved. As a first step in investigating a possible relationship between HLA class II genes and IgAN, we analyzed the extent of linkage disequilibrium (LD) in this region of chromosome 6p21.3 in a Japanese test population and found extended LD blocks within the class II locus. We designed a case-control association study of single-nucleotide polymorphisms (SNPs) in each of those LD blocks, and determined that SNPs located in the HLA- DRA gene were significantly associated with an increased risk of IgAN ( P = 0.000001, odds ratio = 1.91 [95% confidence interval 1.46-2.49]); SNPs in other LD blocks were not. Our data imply that some haplotype of the HLA- DRA locus has an important role in the development of IgAN in Japanese patients.
