Abstract

In developed countries, age-related macular degeneration is a common cause of blindness in the elderly. A common polymorphism, encoding the sequence variation Y402H in complement factor H (CFH), has been strongly associated with disease susceptibility. Here, we examined 84 polymorphisms in and around CFH in 726 affected individuals (including 544 unrelated individuals) and 268 unrelated controls. In this sample, 20 of these polymorphisms showed stronger association with disease susceptibility than the Y402H variant. Further, no single polymorphism could account for the contribution of the CFH locus to disease susceptibility. Instead, multiple polymorphisms defined a set of four common haplotypes (of which two were associated with disease susceptibility and two seemed to be protective) and multiple rare haplotypes (associated with increased susceptibility in aggregate). Our results suggest that there are multiple disease susceptibility alleles in the region and that noncoding CFH variants play a role in disease susceptibility.

  • Conditioning on the risk alleles and examining each of the 19 implicated loci for variants with independent association resulted in identification of previously well documented independently associated variants near CFH and C2/CFB and additional independent signals near C3, CETP, LIPC, FRK/COL10A1, IER3/DDR1, RAD51B.

    “This analysis resulted in the identification of the previously well documented independently associated variants near CFH and C2/CFB8,10,31,32 and of additional independent signals near C3, CETP, LIPC, FRK/COL10A1, IER3/DDR1, RAD51B (Supplementary Table 6).”
  • An early attempt at fine mapping the CFH region showed that more than 20 variants in and around CFH were even more strongly associated with disease than the Y402H coding variant, potentially suggesting that regulation of expression of CFH and neighboring genes, rather than alterations in the coding sequence of CFH, mediates AMD susceptibility.

    “An early attempt at fine mapping the region showed that >20 variants in and around CFH were even more strongly associated with disease than was the Y402H coding variant, potentially suggesting that regulation of the expression of CFH and neighboring genes, rather than alterations in the coding sequence of CFH, mediates AMD susceptibility (97).”
  • A single locus can contain multiple independent common risk variants; for example, seven independent alleles at 8q24 for prostate cancer, three at CFH for AMD, three at IRF5 for SLE, and two at IL23R for Crohn's disease.

    “5) A single locus can contain multiple independent common risk variants. Intensive study has already identified seven independent alleles at 8q24 for prostate cancer (92), three at complement factor H (CFH) for age-related macular degeneration (93, 94), three at IRF5 for systemic lupus erythematosus (95), and two at IL23R for Crohn’s disease (96).”

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.
