Abstract

By analyzing late-onset Alzheimer's disease (LOAD) in a genome-wide association study (313,504 SNPs, three series, 844 cases and 1,255 controls) and evaluating the 25 SNPs with the most significant allelic association in four additional series (1,547 cases and 1,209 controls), we identified a SNP (rs5984894) on Xq21.3 in PCDH11X that is strongly associated with LOAD in individuals of European descent from the United States. Analysis of rs5984894 by multivariable logistic regression adjusted for sex gave global P values of 5.7 x 10(-5) in stage 1, 4.8 x 10(-6) in stage 2 and 3.9 x 10(-12) in the combined data. Odds ratios were 1.75 (95% CI = 1.42-2.16) for female homozygotes (P = 2.0 x 10(-7)) and 1.26 (95% CI = 1.05-1.51) for female heterozygotes (P = 0.01) compared to female noncarriers. For male hemizygotes (P = 0.07) compared to male noncarriers, the odds ratio was 1.18 (95% CI = 0.99-1.41).

  • Prior genome-wide association studies of AD all identified strong evidence for association to APOE but less convincing evidence implicating other genes.

    “All have identified strong evidence for association to APOE, but less convincing evidence implicating other genes2 -9 .”

    From Genome-wide association study identifies variants at CLU and PICALM associated with Alzheimer's disease (2009) · cites this paper as [5]

    The paper reports that only APOE-linked SNPs reached genome-wide significance in its stage I GWAS (Methods, Statistical Analyses; page unavailable), supporting the APOE portion. It does not establish that all prior AD GWAS had this pattern, and its combined-stage analysis reports a genome-wide-significant association for a PCDH11X SNP. (LLM, conf=0.83)

  • Seven of the earliest GWAS, each of which used less than 2,000 cases, identified only APOE as significantly associated with Alzheimer's disease.

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.
