英文摘要

PURPOSE. To investigate whether 11 variants in complement factor H gene contributed differently in patients with neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) of Chinese descent.

METHODS. We performed a case-control study in a group of Chinese patients with nAMD (n = 344) or PCV (n = 368) and contrasted the results against an independent control group comprising 511 mild cataract patients without any evidence of age-related maculopathy. Association analysis of allele and genotype frequencies was performed for 11 haplotypetagging single-nucleotide polymorphisms (SNPs) at the CFH locus (rs1061170, rs1329428, rs1410996, rs2284664, rs375396, rs529825, rs551397, rs7540032, rs800292, rs2274700, and rs1065489). Multinomial logistic regression analyses were performed to estimate and compare the effect of these 11 CFH polymorphisms on AMD and PCV, using the wild-type genotype as reference. Differences in the observed genotypic distributions between cases and controls were tested by using chi(2) tests, with age and sex adjusted for using logistic regression.

RESULTS. CFH rs1065489 was not significantly associated with the nAMD phenotype in Chinese collections either on univariate or multivariate analysis (P > 0.05 for all comparisons). The other 10 SNPs of CFH were significantly associated with the nAMD phenotype. As for PCV, all 11 SNP markers were significantly associated with risk of PCV before or after correction for age and sex differences. Eight of the 11 SNP markers showed significant evidence of heterogeneity between AMD and PCV (P < 0.05 for all comparisons).

CONCLUSIONS. Our data suggest that the genetic architecture at the CFH locus is complex with some markers showing significant skewing of the genotypes toward nAMD or PCV in Asians. This further supports the clinical observation that nAMD and PCV could have distinct pathogenesis mechanisms, which will require larger studies to accurately dissect.
