Abstract excerpt
Clonal expansions of hematopoietic cells carrying mosaic chromosomal alterations (mCAs) are commonly detectable in elderly individuals. Here we studied 43,617 autosomal mCAs ascertained in 484,081 UK Biobank participants using new, high-resolution computational methods to analyze blood-derived, whole-genome sequencing data. Shorter mCAs (≤1 Mb) clustered at 53 genomic hotspots (46 previously undetected), several...
