A SNP (rs547154) in the C2 gene and three SNPs (rs541862, rs2072633, rs4151667) in the CFB gene were genotyped, and case-control studies were performed in subjects with these PCV subtypes.
With meta-analyses, variants in four genes were found to be significantly associated with PCV: LOC387715 rs10490924 (n=9, allelic odds ratio [OR]=2.27, p<0.00001), HTRA1 rs11200638 (n=4, OR=2.72, p<0.00001), CFH rs1061170 (n=4, OR=1.72, p<0.00001), CFH rs800292 (n=5, OR=2.10, p<0.00001), and C2 rs547154 (n=3, OR=0.56, p=0.01).
We performed an association analysis between PCV and polymorphisms across the C2-CFB-RDBP-SKIV2L region in a Japanese population, genotyping 13 single nucleotide polymorphisms (SNPs) spanning this region, including rs9332739 (E318D), rs547154, rs4151667 (L9H), and rs641153 (R32Q) that are known to be associated with age-related macular degeneration (AMD).
