Shared Genetic Architecture Between COVID-19 Severity and Alzheimer's Disease Across European and African Ancestries.

ABSTRACT: The global outbreak of COVID-19, caused by the SARS-CoV-2 virus, has been linked to long-term neurological complications, including an increased risk of Alzheimer's disease (AD) among older adults. However, the precise genetic impact of COVID-19 on long-term AD development remains unclear. This study leveraged genome-wide association study (GWAS) data and genotype data to explore the genetic association between AD and various COVID-19 phenotypes across European ancestry (EA) and African ancestry (AA) cohorts, and the possibility of a causal effect of COVID-19 on AD. We first calculated polygenic risk scores (PRSs) of three COVID-19 phenotypes in AD cases and controls from both EA and AA populations, then determined the genetic associations between COVID-19 PRSs and AD by logistic regressio
