The data being submitted is from participants from the Knight-ADRC MAP study.

Genotyping for 4495 participants were generated through 10 different genotyping arrays (Infinium CoreExome-24, Infinium Neuro Consortium Array, Infinium Global Screening Array-24, Infinium OmniExpress-24, Illumina Human660W-Quad, Human610-Quad, Illumina Omni1-Quad, Affy UK Biobank Axiom, Infinium OmniExpressExome-8, and Illumina Human1M-Duo). In particular, 1955 AD cases (57% Females, 56% APOE4+, average age 74), 839 ADRD participants (51% females, 34% APOE4+, average age 63), and 1699 cognitively healthy participants (60% Females, 31% APOE4+, average age 74) individuals are being submitted. Approximately 85% of the samples are self-defined as “White”, and 10% are self-defined as “African-American”.
