Somatic mutation and clonal expansions in human tissues

Genome Med. 2019 May 28;11(1):35. doi: 10.1186/s13073-019-0648-4.

Abstract

Recent sequencing studies on healthy skin and esophagus have found that, as we age, these tissues become colonized by mutant clones of cells carrying driver mutations in traditional cancer genes. This comment summarizes these findings and discusses their possible implications for our understanding of cancer, ageing, and other diseases.
