FAS is a member of the TNF-receptor superfamily. The FAS protein is a receptor for TNFSF6/FASLG and has been shown to play a central role in the physiological regulation of programmed cell death, and has been implicated in the pathogenesis of various malignancies and diseases of the immune system. Several alternatively spliced transcript variants have been described, some of which are candidates for nonsense-mediated mRNA decay (NMD). The isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full length isoform.

Phase: Two
QA State: Under Review


No additional breast data available.

Performance Comment

FAS was one of numerous potential early detection biomarkers specific to triple-negative breast cancer in multiple pathways identified.



Phase: Three
QA State: Under Review


APO-1/Fas receptor (FasR) is a cell surface receptor that, when activated, triggers apoptosis. It has been postulated that this receptor may be involved in the clearance of benign ovarian epithelial inclusion cysts (IC). An observed decreased expression of FasR in malignant ovarian epithelial neoplasms as compared with benign ovarian epithelial lesions suggests that a decreased sensitivity to Fas-mediated apoptosis may be involved in ovarian epithelial carcinogenesis.
