Description:INTRODUCTION:
Most Alzheimer disease (AD) loci were discovered in European ancestry individuals.
METHODS:
We applied principal component analysis using Gaussian mixture models and an Ashkenazi Jewish (AJ) reference genome-wide association study (GWAS) dataset to identify AJs ascertained in GWAS (n=42,682), whole genome sequencing (WGS, n=16,815) and whole exome sequencing (WES, n=20,504) datasets. Association of AD was tested genome-wide (GW) in the GWAS and WGS datasets and exome-wide (EW) in all three datasets (EW). Gene-based analyses were performed using aggregated rare variants.
RESULTS:
In addition to APOE, GW analyses (1,355 cases and 1,661 controls) revealed associations with TREM2 R47H (P=9.66x10−9), rs541586606 near RAB3B (P=5.01x10−8) and rs760573036 between SPOCK3 and ANXA10 (P=6.32x10−8). In EW analyses (1,504 cases and 2,047 controls), study-wide significant association was observed with rs1003710 near SMAP2 (P=1.91x10−7). A significant gene-based association was identified with GIPR (P=7.34x10−7).
DISCUSSION:
Our results highlight the efficacy of founder populations for AD genetic studies.
