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 conducted an association analysis between CFH variants and PCV in a Japanese population, genotyping 12 tag single nucleotide polymorphisms (SNPs)-including rs3753394, rs800292 (I62V), and rs1061170 (Y402H)-that are highly representative of the common genetic variation in the CFH region.
There was no significant difference in the incidence of CFH Y402H (P = 0.598) and HTRA1 rs11200638 (P = 0.290) between eyes with typical exudative AMD and with PCV.
