Abstract

Debra A. Schaumberg, ScD, OD, MPH; Susan E. Hankinson, ScD; Qun Guo, MSc; Eric Rimm, ScD; David J. Hunter, MBBS, ScDObjectivesTo delineate the magnitude of susceptibility to age-related macular degeneration (AMD) due to common variants in the gene for complement factor H (CFH) and the predicted gene LOC387715 and to determine whether these variants interact with modifiable risk factors.MethodsWe compared cases who developed AMD (n = 457) with 1071 age- and sex-matched control subjects in a prospective nested case-control study within the Nurses' Health Study and the Health Professionals Follow-up Study. We determined the incidence rate ratios and 95% confidence intervals (CIs) for AMD for each genotype and examined the interactions with modifiable risk factors.ResultsParticipants with 1 or 2 copies of the Y402H variant of CFH were, respectively, 1.98 (95% CI, 1.64-2.40) and 3.92 (95% CI, 2.69-5.76) times more likely to develop AMD, whereas the incident rate ratios (95% CIs) for 1 and 2 copies of LOC387715 A69S were 2.38 (1.92-2.96) and 5.66 (3.69-8.76), respectively. The fraction of AMD cases attributable to these 2 variants was 63% (95% CI, 58%-68%). Subjects homozygous for both risk alleles had a 50-fold increased risk of AMD (95% CI, 10.8-237), and cigarette smoking and obesity multiplied the risks associated with these variants.ConclusionAge-related macular degeneration has emerged as a paradigmatic example of a common disease caused by the interplay of genetic predisposition and exposure to modifiable risk factors.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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.
