Mutational landscape and underlying mutational processes in chronic lymphocytic leukemia

Mol Cell Oncol. 2016 Mar 10;3(4):e1157667. doi: 10.1080/23723556.2016.1157667. eCollection 2016 Jul.

Abstract

Sequencing studies have been instrumental in understanding the genetic basis of chronic lymphocytic leukemia (CLL). Our recent whole-genome sequencing study focusing on lower cytogenetic risk CLL demonstrated that CLL mutations can be attributed to 3 key mutational processes-2 types of activation induced-cytidine deaminase (AID) signatures and an aging signature-that operate at different times throughout CLL evolution.

Keywords: CLL; Whole genome sequencing; mutation signature; somatic hypermutation.
