STUB1 and Alzheimer disease: Recently, technological advances have enabled the detection of not only CHIP,9 but also mCAs from whole-genome sequencing (WGS) with a higher sensitivity than genotyping arrays.10 Here, we explore the association of autosomal mCAs in blood, including copy number gains and losses, and copy number neutral loss of heterozygosity (CN-LOH), with AD using WGS of a large multi-ancestry cohort of the Alzheimer’s Disease Sequencing Project (ADSP) consortium.11,12
