Overview

FAS encodes a cell surface receptor involved in the induction of apoptosis. FAS mutations are common in DLBCL and may be more frequent in primary gastric DLBCL.1,2 Mutations also occur in FL at a lower rate.3 Although reported in one BL study,4 overall the evidence for FAS mutations in BL remains sparse. Mutations in FAS often lead to a loss of function, making lymphoma cells resistant to Fas ligand-induced apoptosis, thereby allowing malignant cells to evade immune surveillance.5 In mouse models, Fas mutations led to a significantly shorter lymphoma-specific survival and reduced sensitivity to chemotherapy.5

Experimental Evidence

Driver mutations affecting this gene in FL/DLBCL have been experimentally demonstrated to cause a reduction or loss of function (LOF).6
