Scientists may have underestimated how much genes contribute to Alzheimer's risk
A large multi-ancestry genetic analysis identified 127 genomic loci associated with Alzheimer's disease, including 48 previously unreported loci, and implicated microglial and neuronal gene-expression patterns in disease susceptibility. The researchers estimated that common genetic variants account for 16% of Alzheimer's disease liability in European-ancestry populations, substantially higher…
