The meta-analyses showed that the most-studied SNP rs2511989 was not significantly associated with all forms of AMD, neovascular AMD, or PCV in East Asians (P = 0.98, 0.93 and 0.30, respectively) but was associated with AMD in Caucasians (P = 0.04 for all AMD and 0.004 for neovascular AMD).
Although we compared the genotypic distributions of rs2511989 in typical AMD and PCV patients against 2 independent control groups (cataract patients and healthy Japanese individuals), SERPING1 rs2511989 was not significantly associated with typical AMD (P = 0.932 and 0.513, respectively) or PCV (P = 0.505 and 0.141, respectively).
We found no evidence to support the role of any common SERPING1 variants, including the rs2511989 variant, in the susceptibility to PCV in a Chinese Han population.
