Gene Description | ARID2, AT-rich interaction domain 2, is a member of the PBaF subunit (PMID: 32303701) of the SWI/SNF chromatin remodeling complex and is involved in cell-cycle activation (PMID: 29072391). Arid2 loss of function has been identified in hepatoceullar carcinoma (PMID: 22095441, PMID: 28238438), NSCLC (PMID: 23047306), papillary renal cell carcinoma (PMID: 25790038), oral squamous cell carcinoma (PMID: 29072391), urothelial carcinoma, and melanoma (PMID: 32303701). | ||||||||||

ARID2 inact mut | melanoma | not predictive | unspecified immune checkpoint inhibitor | Clinical Study - Cohort | Actionable | In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including ARID2, did not correlate with improved survival in 2 separate cohorts of patients with melanoma treated with systemic immune checkpoint inhibitors, with adjusted HRs for overall survival of 1.70 (p=0.192, n=86) and 1.02 (p=0.939, n=192), respectively (PMID: 32321774). | 32321774 |
ARID2 inact mut | transitional cell carcinoma | not predictive | unspecified immune checkpoint inhibitor | Clinical Study - Cohort | Actionable | In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including ARID2, did not correlate with improved survival in 2 separate cohorts of patients with transitional cell carcinoma treated with systemic immune checkpoint inhibitors, with adjusted HRs for overall survival of 1.44 (p=0.34, n=56) and 0.82 (p=0.559, n=93), respectively (PMID: 32321774). | 32321774 |
ARID2 inact mut | head and neck squamous cell carcinoma | not predictive | unspecified immune checkpoint inhibitor | Clinical Study - Cohort | Actionable | In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including ARID2, did not correlate with improved survival in 2 separate cohorts of patients with head and neck squamous cell carcinoma treated with systemic immune checkpoint inhibitors, with adjusted HRs for overall survival of 0.74 (p=0.631, n=31) and 0.76 (p=0.622, n=68), respectively (PMID: 32321774). | 32321774 |
ARID2 inact mut | colorectal adenocarcinoma | unknown | unspecified immune checkpoint inhibitor | Clinical Study - Cohort | Actionable | In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including ARID2, correlated with improved survival in one cohort of patients with colorectal adenocarcinoma treated with systemic immune checkpoint inhibitors but not the other, with adjusted HRs for overall survival of 0.30 (p=0.03, n=35) and 0.56 (p=0.244, n=63), respectively (PMID: 32321774). | 32321774 |
ARID2 inact mut | gastroesophageal adenocarcinoma | not predictive | unspecified immune checkpoint inhibitor | Clinical Study - Cohort | Actionable | In a retrospective analysis, somatic loss-of-function mutations in the genes of the mSWI/SNF complex, including ARID2, did not correlate with improved survival in 2 separate cohorts of patients with gastroesophageal adenocarcinoma treated with systemic immune checkpoint inhibitors, with adjusted HRs for overall survival of 0.70 (p=0.403, n=66) and 0.46 (p=0.071, n=59), respectively (PMID: 32321774). | 32321774 |
