Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the FAS gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Receptor for TNFSF6/FASLG. The adapter molecule FADD recruits caspase-8 to the activated receptor. The resulting death- inducing signaling complex (DISC) performs caspase-8 proteolytic activation which initiates the subsequent cascade of caspases (aspartate-specific cysteine proteases) mediating apoptosis. FAS- mediated apoptosis may have a role in the induction of peripheral tolerance, in the antigen-stimulated suicide of mature T-cells, or both. The secreted isoforms 2 to 6 block apoptosis (in vitro). {ECO:0000269|PubMed:19118384, ECO:0000269|PubMed:7533181}.
• Disease: DISEASE: Autoimmune lymphoproliferative syndrome 1A (ALPS1A) [MIM:601859]: A disorder of apoptosis that manifests in early childhood and results in the accumulation of autoreactive lymphocytes. It is characterized by non-malignant lymphadenopathy with hepatosplenomegaly, and autoimmune hemolytic anemia, thrombocytopenia and neutropenia. {ECO:0000269|PubMed:10090885, ECO:0000269|PubMed:10340403, ECO:0000269|PubMed:10515860, ECO:0000269|PubMed:11418480, ECO:0000269|PubMed:17336828, ECO:0000269|PubMed:20935634, ECO:0000269|PubMed:7540117, ECO:0000269|PubMed:8929361, ECO:0000269|PubMed:9028321, ECO:0000269|PubMed:9028957, ECO:0000269|PubMed:9322534, ECO:0000269|PubMed:9821419, ECO:0000269|PubMed:9927496}.
