What is the official name of the FAS gene?
The official name of this gene is “Fas cell surface death receptor.”
FAS is the gene's official symbol. The FAS gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the FAS gene?
The FAS gene provides instructions for making a protein involved in signaling that initiates a process called a caspase cascade. The caspase cascade results in the self-destruction of cells (apoptosis). Three FAS proteins group together to form a structure called a trimer. This trimer then interacts with other molecules to perform its signaling function.
Does the FAS gene share characteristics with other genes?
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

Where is the FAS gene located?
Cytogenetic Location: 10q24.1
Molecular Location on chromosome 10: base pairs 90,750,287 to 90,775,541
The FAS gene is located on the long (q) arm of chromosome 10 at position 24.1.
More precisely, the FAS gene is located from base pair 90,750,287 to base pair 90,775,541 on chromosome 10.
