The public catalogues list it as an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Endometrial cancer, Bladder & urothelial cancer, Breast cancer and 5 more.","summary":"Rho GTPase-activating protein (GAP). Binds several acidic phospholipids which inhibits the Rho GAP activity to promote the Rac GAP activity. This binding is inhibited by phosphorylation by PRKCA.\n\nCIViC holds 4 clinical evidence items and 0 assertions across 4 variants. Open Targets scores its association with cancer at 0.75 (direct and indirect evidence; datatypes literature 0.93, animal model 0.46, genetic association 0.00, somatic mutation 0.90). IntOGen calls it a driver in 15 cohorts (1 activating, 14 loss-of-function), covering Acute Myeloid Leukaemia, Basal Cell Carcinoma, Bladder Urothelial Carcinoma, Invasive Breast Carcinoma, Renal Clear Cell Carcinoma, Lung Squamous Cell Carcinoma and others.","asOf":"2026-09-23","links":[{"label":"HGNC HGNC:4591","url":"https://www.genenames.org/data/gene-symbol-report/#!/hgnc_id/HGNC:4591"},{"label":"UniProt Q9NRY4","url":"https://www.uniprot.org/uniprotkb/Q9NRY4/entry"},{"label":"NCBI Gene 2909","url":"https://www.ncbi.nlm.nih.gov/gene/2909"},{"label":"Ensembl ENSG00000160007","url":"https://www.ensembl.org/Homo_sapiens/Gene/Summary?g=ENSG00000160007"}],"tags":["cancer-genes-wave"],"related":["civic","open-targets","intogen"],"cancers":["endometrial","urothelial","breast-cancer","rcc","ovarian","skin-cancer","lung-cancer","basal-cell-carcinoma"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":["Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling.

Involved in cell differentiation as well as cell adhesion and migration, plays an important role in retinal tissue morphogenesis, neural tube fusion, midline fusion of the cerebral hemispheres and mammary gland branching morphogenesis. Transduces signals from p21-ras to the nucleus, acting via the ras GTPase-activating protein (GAP).
