Forest plots of the two most strongly associated SNPs, rs3781834 (A) and rs11218343 (B), in the <i>SORL1</i> region showing the strength and pattern of significance in the Japanese discovery and each replication dataset in the model of adjusting for population structure, age, and sex.

Regional association plot for the <i>SORL1</i> region on chromosome 11 in the three-stage design.

<p>For each SNP, the chromosomal location is shown on the x-axis and the significance level for association with LOAD is indicated by a –log₁₀P value on the y-axis. P-values are expressed as –log₁₀(P) (y-axis) for every tested SNP ordered by chromosomal location (x-axis). Genomic position was determined using the NCBI database (Build 37.1). Computed estimates of linkage disequilibrium (LD; r²) between SNPs in this region with the top-ranked SNP (rs3781834) in the Japanese discovery (J1) dataset are shown as red circles for r²≥0.8, orange circles for 0.5≤r²<0.8, light blue circles for 0.2≤r²<0.5, and dark blue circles for r²<0.2 using hg19/1000 Genomes of Asian populations (ASN; release on November 2010) combined from Han Chinese (CHB) and Japanese (JPT). Meta-analysis <i>P</i>-values are shown as purple diamonds for the Japanese datasets (J1+J2) and all datasets (J1+J2+K+C) including Japanese, Korean (K), and Caucasians (C). Two genome-wide significant SNPs in the final stage (rs3781834 and rs11218343) are presented. The gene structure and reading frame are shown below the plot. Exons are denoted with vertical bars. The LD between rs3781834 and rs11218343 is 0.57 in the ASN reference population.</p
