ATG16L1
Chr 2autophagy related 16 like 1
Also known as: APG16L, ATG16A, ATG16L, IBD10, WDR30
ATG16L1 encodes a protein that is essential for autophagy, mediating the conjugation of phosphatidylethanolamine to ATG8 family proteins to control autophagosomal membrane elongation and also participating in non-canonical autophagy pathways. Mutations cause susceptibility to inflammatory bowel disease, particularly Crohn disease, with the gene being highly constrained against loss-of-function variants (pLI 0.96, LOEUF 0.32). The protein also regulates innate immune responses and Paneth cell function in the intestinal epithelium.
Primary Disease Associations & Inheritance
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
