KIF3A and Alzheimer disease: A previous GWAS of AD has identified a peak marker (rs2897442) located in an intron of KIF3A in the 5q31 genomic region (18) This signal is located >50 kb away from the site of association reported here, yielded P-values of lower significance (Table 4), and demonstrates only minimal levels of LD (r2 < 0.1, D’ < 0.4 based on the CEU 1000 Genomes dataset) with the five replicated SNPs in this current study.
