SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1 (SMARCB1) is a gene that encodes a protein that functions in the removal of suppressive chromatin structures so that transcription may occur. Missense mutations, nonsense mutations, silent mutations, frameshift insertions and deletions, and in-frame insertions and deletions are observed in cancers such as bone cancer, central nervous system cancer, and intestinal cancer.

SMARCB1 is altered in 1.11% of all cancers with colon adenocarcinoma, lung adenocarcinoma, breast invasive ductal carcinoma, bladder urothelial carcinoma, and endometrial endometrioid adenocarcinoma having the greatest prevalence of alterations [3].

SMARCB1 GENIE Cases - Top Diseases

The most common alterations in SMARCB1 are SMARCB1 Mutation (0.68%), SMARCB1 Loss (0.21%), SMARCB1 Amplification (0.19%), SMARCB1 R377H (0.09%), and SMARCB1 K364del (0.04%) [3].
