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 8.86% of all cancers with uterine corpus neoplasm, non-small cell lung carcinoma, breast carcinoma, colorectal adenocarcinoma, and bladder carcinoma having the greatest prevalence of alterations [3].
