Genes affected

FAF1 (HGNC:3578): (Fas associated factor 1) Interaction of Fas ligand (TNFSF6) with the FAS antigen (TNFRSF6) mediates programmed cell death, also called apoptosis, in a number of organ systems. The protein encoded by this gene binds to FAS antigen and can initiate apoptosis or enhance apoptosis initiated through FAS antigen. Initiation of apoptosis by the protein encoded by this gene requires a ubiquitin-like domain but not the FAS-binding domain. [provided by RefSeq, Jul 2008]

Aug 11, 2022

The c.819G>C (p.Q273H) alteration is located in exon 9 (coding exon 9) of the FAF1 gene. This alteration results from a G to C substitution at nucleotide position 819, causing the glutamine (Q) at amino acid position 273 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
