Study design flowchart. In the PRS analysis, “Base” data is used to provide effect sizes for SNPs shared with individuals in the “Target” data. Using PRSice-2, 20 genera were found to be significantly genetically associated with AD diagnosis in the discovery sample. Three genera were validated in the replication sample, and ten were confirmed by a meta-analysis from discovery and replicate samples. Linear regression analyses were used to determine the genetic correlation between the PRSs for ten significant genera and APOE genotyping. Three genera were identified as genetically correlated with APOE rs429358 risk allele C.
