ATG16L1 Gene

Autophagy Related 16 Like 1 (ATG16L1) is a gene involved in autophagosome formation / intestinal homeostasis that has been studied in relation to immune function, metabolism, and chronic illness. Variants in ATG16L1 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the ATG16L1 gene?

ATG16L1 encodes autophagy related 16 like 1, a protein involved in autophagosome formation / intestinal homeostasis. It belongs to the Autophagy category and is part of the Mitochondrial Energy Production & PEM biological cluster. ATG16L1 is a component of the ATG12-ATG5-ATG16L1 complex; rs2241880 T300A variant affects Paneth cell function and is a major Crohn's disease risk factor.

Biological role and pathway

ATG16L1 is involved in the autophagosome formation / intestinal homeostasis pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Mitochondrial Energy Production & PEM cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

ATG16L1 and Long COVID / ME-CFS research

ATG16L1 T300A increases caspase-3-mediated cleavage, impairing Paneth cell secretory function and gut autophagy; this common variant may affect gut homeostasis and microbiome dysbiosis in Long COVID.
