SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 (SMARCA4) is a gene that encodes a protein that functions in the regulation of transcription via its helicase and ATPase activity. Missense mutations, nonsense mutations, silent mutations, and in-frame deletions are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.

SMARCA4 is altered in 4.59% of all cancers with lung adenocarcinoma, colon adenocarcinoma, endometrial endometrioid adenocarcinoma, bladder urothelial carcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

SMARCA4 GENIE Cases - Top Diseases

The most common alterations in SMARCA4 are SMARCA4 Mutation (3.78%), SMARCA4 Amplification (0.28%), SMARCA4 Loss (0.10%), SMARCA4 T910M (0.09%), and SMARCA4 R1192H (0.04%) [3].
