IFITM3

IFITM3

A gene on chromosome 11p15.5 that encodes an interferon-induced protein, which mediates innate cellular immunity against viral pathogens—e.g., influenza A H1N1, West Nile, and dengue viruses—by inhibiting the early steps of viral replication.
 
Molecular pathology
IFITM3 mutations are linked to increased susceptibility to viral infections.
