Complement activation is common in patients with IgA nephropathy (IgAN) and
associated with disease severity. Our recent genome-wide association study of
IgAN identified susceptibility loci on 1q32 containing the complement regulatory
protein-encoding genes CFH and CFHR1-5, with rs6677604 in CFH as the top
single-nucleotide polymorphism and CFHR3-1 deletion (CFHR3-1?) as the top signal
for copy number variation. In this study, to explore the clinical effects of
variation in CFH, CFHR3, and CFHR1 on IgAN susceptibility and progression, we
enrolled two populations. Group 1 included 1178 subjects with IgAN and available
genome-wide association study data. Group 2 included 365 subjects with IgAN and
available clinical follow-up data. In group 1, rs6677604 was associated with
mesangial C3 deposition by genotype-phenotype correlation analysis. In group 2,
we detected a linkage between the rs6677604-A allele and CFHR3-1? and found that
the rs6677604-A allele was associated with higher serum levels of CFH and lower
levels of the complement activation split product C3a. Furthermore, CFH levels
were positively associated with circulating C3 levels and negatively associated
with mesangial C3 deposition. Moreover, serum levels of the pathogenic
galactose-deficient glycoform of IgA1 were also associated with the degree of
mesangial C3 deposition in patients with IgAN. Our findings suggest that genetic
variants in CFH, CFHR3, and CFHR1 affect complement activation and thereby,
predispose patients to develop IgAN.
