Immunity-related GTPase family M protein (IRGM), also known as interferon-inducible protein 1 (IFI1), is an enzyme that in humans is IRGM gene.^[3]

IRGM is a member of the interferon-inducible GTPase family. The encoded protein may play a role in the innate immune response by regulating autophagy formation in response to intracellular pathogens.

Clinical relevance

Polymorphisms that affect the normal expression of this gene are associated with a susceptibility to Crohn's disease and tuberculosis.^[4]
