Mosaic chromosome Y loss is associated with alterations in blood cell counts in UK Biobank men
Abstract Mosaic loss of Y chromosome (mLOY) is the most frequently detected somatic copy number alteration in leukocytes of men. In this study, we investigate blood cell counts as a potential mechanism linking mLOY to disease risk in 206,353 UK males. Associations between mLOY, detected by genotypin...
