A haplotype in CFH family genes confers high risk of rare glomerular nephropathies.

ABSTRACT: Despite distinct renal lesions, a series of rare glomerular nephropathies are reportedly mediated by complement overactivation. Genetic variations in complement genes contribute to disease risk, but the relationship of genotype to phenotype has not been straightforward. Here, we screened 11 complement genes from 91 patients with atypical hemolytic uremic syndrome (aHUS), C3 glomerulopathy (C3G) and membranoproliferative glomerulonephritis type I (MPGN I), and identified the concomitant presence of three missense variations located within the human complement Factor H (CFH) gene cluster. The three variations, rs55807605, rs61737525 and rs57960694, have strong linkage disequilibrium; subsequent haplotype analysis indicated that ATA increased the susceptibility of these renal diseases.
