通过在全基因组关联研究中分析晚发性阿尔茨海默病(LOAD),(313,504个SNP,3个系列,844例病例/1,255例对照),并在另外4个系列中评估25个SNP与最显著的等位基因关联(1,547例/1,209例对照),我们确定了PCDH 11 X中Xq21.3上的SNP(rs 5984894),该SNP与美国高加索人的LOAD密切相关。通过多变量logistic回归分析rs 5984894(经性别校正),I期总体P值为5.7×10-5,II期为4.8×10-6,合并数据为3.9×10-12。与女性非携带者相比,女性纯合子(P=2.0×10-7)和女性杂合子(P=0.01)的比值比分别为1.75(95%CI 1.42-2.16)和1.26(95%CI 1.05-1.51)。男性半合子(P=0.07)与男性非携带者相比,优势比为1.18(95% CI 0.99-1.41)。
By analyzing late onset Alzheimer's disease (LOAD) in a genome wide association study (313,504 SNPs, 3 series, 844 cases/1,255 controls) and evaluating the 25 SNPs with most significant allelic association in 4 additional series (1,547 cases/1,209 controls), we identified a SNP (rs5984894) on Xq21.3 in PCDH11X that is strongly associated with LOAD in American Caucasians. Analysis of rs5984894 by multivariable logistic regression adjusted for sex gave global P values of 5.7×10-5 in stage I, 4.8×10-6 in stage II, and 3.9×10-12 in the combined data. Odds ratios were 1.75 (95% CI 1.42-2.16) for female homozygotes (P=2.0×10-7) and 1.26 (95% CI 1.05-1.51) for female heterozygotes (P=0.01) compared to female non-carriers. For male hemizygotes (P=0.07) compared to male non-carriers the odds ratio was 1.18 (95% CI 0.99-1.41).
