Gene Description | ARID1A, AT-rich interaction domain 1A, is a member of the cBaF subunit (PMID: 32303701) of the SWI/SNF chromatin remodeling complex and is involved in cell-cycle activation (PMID: 29136504). ARID1A has been reported to influence PI3K/AKT pathways (PMID: 24618703), and loss of function is commonly found in ovarian clear cell carcinoma (PMID: 32020380, PMID: 32027624), gastric, colorectal (PMID: 28937020), and bladder cancers (PMID: 28583311), while in liver cancer, Arida1a has a context dependent role (PMID: 29136504) and ARID1A promoter hypermethylation has been observed in squamous cell carcinoma (PMID: 32015157). | ||||||||||
