Fig. 1From: Germline, hematopoietic, mosaic, and somatic variation: interplay between inherited and acquired genetic alterations in disease assessmentGenetic variation attributable to distinct biological processes. Variants detected by genetic testing may fall into at least four categories, including inherited germline variants, post-zygotic somatic mosaic mutations, lineage-restricted somatic mutations, such as in age-related clonal hematopoiesis, and somatic mutations related to cancer (neoplasia)Back to article page
