The public catalogues list it as a drug target, an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Colorectal cancer, Pancreatic ductal adenocarcinoma, Breast cancer and 5 more.","summary":"UniProt has no function text for O95467; HGNC names it \"GNAS complex locus\".\n\nCIViC holds 17 clinical evidence items and 0 assertions across 5 variants, naming Trametinib, Palbociclib, Vemurafenib and Gefitinib and others.
