Abstract

A human germline-mosaic for WT and DNMT3A mutant cells reveals a marked advantage for DNMT3A mutant cells in the hematopoietic system compared to epithelial cells. Deep sequencing suggests a very early tissue advantage driven by DNA methylation loss at conserved loci rather than increased mutation burden.
