ATG16L1 and irritable bowel syndrome: Based on wide-genome studies, gene variants in genes such as ATG16L1 (rs2241880: OR = 0.74; 95% CI: 0.65–0.84; p < 0.001), PTPN2 (Protein tyrosine phosphatase non-receptor type 2) and of IL-23R (rs11209026 allele A; OR = 0.32; 95% CI: 0.17–0.60; p < 0.001) were related to increased susceptibility to IBD, and even to disease course and treatment outcomes [13].
