Associations between ATG SNPs and some diseases have been identified in multiple populations; e.g., the associations between polymorphisms in ATG16L1 with inflammatory Crohn disease (Hampe et al., 2007), palmoplantar pustulosis (Douroudis et al., 2011), and psoriasis vulgaris (Douroudis et al., 2012), as well as polymorphisms in ATG10 with breast cancer (Qin et al., 2013) and Vogt–Koyanagi–Harada syndrome (Zheng et al., 2015). Here, ATG16L1 is linked to palmoplantar pustulosis.
