AT rich interactive domain 1A (SWI-like) (ARID1A) is a gene that encodes a protein that is included in the SWI/SNF family and functions in the transcriptional activation of genes. Fusions, missense mutations, nonsense mutations, silent mutations, frameshift insertions and deletions, and in-frame insertions and deletions are observed in cancers such as biliary tract cancers, endometrial cancer, and intestinal cancer.

ARID1A is altered in 7.53% of all cancers with endometrial endometrioid adenocarcinoma, lung adenocarcinoma, colon adenocarcinoma, bladder urothelial carcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

ARID1A GENIE Cases - Top Diseases

The most common alterations in ARID1A are ARID1A Mutation (9.03%), ARID1A Frameshift (3.55%), ARID1A Nonsense (2.79%), ARID1A D1850Tfs*33 (0.18%), and ARID1A Deletion (0.17%) [3].
