Abstract

Age-related macular degeneration (AMD) is the most frequent cause of irreversible blindness in the elderly in developed countries. Our previous studies implicated activation of complement in the formation of drusen, the hallmark lesion of AMD. Here, we show that factor H (HF1), the major inhibitor of the alternative complement pathway, accumulates within drusen and is synthesized by the retinal pigmented epithelium. Because previous linkage analyses identified chromosome 1q25-32, which harbors the factor H gene ( HF1 / CFH ), as an AMD susceptibility locus, we analyzed HF1 for genetic variation in two independent cohorts comprised of ≈900 AMD cases and 400 matched controls. We found association of eight common HF1 SNPs with AMD; two common missense variants exhibit highly significant associations (I62V, χ 2 = 26.1 and P = 3.2 × 10 -7 and Y402H, χ 2 = 54.4 and P = 1.6 × 10 -13 ). Haplotype analysis reveals that multiple HF1 variants confer elevated or reduced risk of AMD. One common at-risk haplotype is present at a frequency of 50% in AMD cases and 29% in controls [odds ratio (OR) = 2.46, 95% confidence interval (1.95-3.11)]. Homozygotes for this haplotype account for 24% of cases and 8% of controls [OR = 3.51, 95% confidence interval (2.13-5.78)]. Several protective haplotypes are also identified (OR = 0.44-0.55), further implicating HF1 function in the pathogenetic mechanisms underlying AMD. We propose that genetic variation in a regulator of the alternative complement pathway, when combined with a triggering event, such as infection, underlie a major proportion of AMD in the human population.

  • The Y402H variant of complement factor H is a major AMD-associated SNP.

    “A major AMD-associated SNP is the Y402H (tyrosine to histidine substitution at amino acid 402) variant of complement factor H (CFH) (Edwards et al., 2005; Hageman et al., 2005; Haines et al., 2005; Klein et al., 2005).”

  • These CFH SNPs have been reported to be major genetic factors for developing AMD in Caucasians.

    “These SNPs have been reported to be major genetic factors for developing AMD in Caucasians (Edwards et al., 2005; Hageman et al., 2005; Haines et al., 2005; Klein et al., 2005; Tuo et al., 2006).”

  • These findings are consistent with human AMD drusen findings and with a critical role of complement overactivity in AMD.

    “These findings are consistent with findings in drusen of humans with AMD (Hageman et al., 2005), as well as the critical role in AMD of complement overactivity, which has been discussed above.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
