The T300A Crohn’s disease risk polymorphism impairs function of the WD40 domain of ATG16L1

Abstract

The T300A substitution in ATG16L is associated with Crohn’s disease risk and disrupts clearance of intracellular pathogens by autophagy. Here the authors show that the mutation impairs interaction of ATG16L with TMEM59 and disrupts unconventional TMEM-induced autophagy, an aspect of innate immunity.
