Genomic analysis of 220 CTCLs identifies a novel recurrent gain-of-function alteration in RLTPR (p.Q575E).

ABSTRACT: Cutaneous T-cell lymphoma (CTCL) is an incurable non-Hodgkin lymphoma of the skin-homing T cell. In early-stage disease, lesions are limited to the skin, but in later-stage disease, the tumor cells can escape into the blood, the lymph nodes, and at times the visceral organs. To clarify the genomic basis of CTCL, we performed genomic analysis of 220 CTCLs. Our analyses identify 55 putative driver genes, including 17 genes not previously implicated in CTCL. These novel mutations are predicted to affect chromatin (BCOR, KDM6A, SMARCB1, TRRAP), immune surveillance (CD58, RFXAP), MAPK signaling (MAP2K1, NF1), NF-κB signaling (PRKCB, CSNK1A1), PI-3-kinase signaling (PIK3R1, VAV1), RHOA/cytoskeleton remodeling (
