CFB and IgA glomerulonephritis: In addition, TNFSF13 rs3803800 showed the most stable effect under five genetic models excepted the overdominant model; CFB rs549182 has a robust impact on susceptibility in all models except the homozygote one; there were two gene variants of CFB (rs549182 and rs4151657) that were significant in different patient groups with IgA nephropathy and we summarized it with ORG in Table 4.
