Abstract

Age-related macular degeneration (AMD) is a common, late-onset disease with seemingly typical complexity: recurrence ratios for siblings of an affected individual are three- to sixfold higher than in the general population, and family-based analysis has resulted in only modestly significant evidence for linkage. In a case-control study drawn from a US-based population of European descent, we have identified a previously unrecognized common, noncoding variant in CFH, the gene encoding complement factor H, that substantially increases the influence of this locus on AMD, and we have strongly replicated the associations of four other previously reported common alleles in three genes (P values ranging from 10(-6) to 10(-70)). Despite excellent power to detect epistasis, we observed purely additive accumulation of risk from alleles at these genes. We found no differences in association of these loci with major phenotypic categories of advanced AMD. Genotypes at these five common SNPs define a broad spectrum of interindividual disease risk and explain about half of the classical sibling risk of AMD in our study population.

  • 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).”
  • This ARMS2/HTRA1 finding was later confirmed in several targeted studies and in a genome-wide association study.

    “This finding was later confirmed in several targeted studies (107) and in a GWAS (37).”
  • The genetic variants known to date are estimated to account for <50% of the heritability of AMD.

    “The genetic variants known to date are estimated to account for <50% of the heritability of the disease (8,20).”
  • Together with strongly associated variants in the ARMS2/HTRA1 region on chromosome 10, these multiple loci have been estimated to explain approximately one-half of the heritability of AMD.

    “Together with strongly associated variants in the *ARMS2/HTRA1* region on chromosome 10 ([12](#r12), [13](#r13)), these multiple loci have been estimated to explain approximately one-half of the heritability of AMD ([6](#r6))”
  • The role of the alternative complement pathway in AMD pathogenesis was documented by the discovery and replication of the CFH association and by reports of three additional risk loci in this pathway: CFB/C2 on chromosome 6, C3 on chromosome 19, and CFI on chromosome 4.

    “The role of the alternative complement pathway in disease pathogenesis was documented by the discovery ([2](#r2)–[5](#r5)) and replication ([6](#r6), [7](#r7)) of the *CFH* association as well as reports of three additional risk loci in this pathway: *CFB/C2* on chromosome 6 ([6](#r6), [8](#r8)), *C3* on chromosome 19 ([9](#r9), [10](#r10)), and *CFI* on chromosome 4 ([11](#r11)).”

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.
