The Association of rs1047763 and rs1008898 of C1GALT1 with IgA Nephropathy Risk: A Global Meta-Analysis

Monoclon Antib Immunodiagn Immunother. 2017 Jun;36(3):95-103. doi: 10.1089/mab.2016.0050.

Abstract

IgA nephropathy (IgAN) is a globally common primary glomerulonephritis characterized by an elevated level of serum IgA and immune complex deposition in the mesangial area. In the serum of patients with IgAN, the hinge region of IgA1 immunoglobulin contains aberrantly glycosylated O-glycans deficient in galactose, which is normally added to the core 1 O-glycan structure by core 1 synthase, glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase 1 (C1GALT1), the key enzyme in the process of glycosylation. It is unknown if single-nucleotide polymorphisms rs1047763 and rs1008898 of C1GALT1 increase the risk of IgAN. We enrolled 5 subjects in this meta-analysis, including a total of 1693 IgAN patients and 1864 control subjects. We performed meta-analysis on associations between rs1047763, rs1008898, and IgAN using the allele model, dominant model, recessive model, and additive model. We found that there was no relationship between rs1047763 and rs1008898 in C1GALT1 and susceptibility to IgAN.

Keywords: IgA nephropathy; genetic polymorphism; meta-analysis.
