Expanded analysis of core components of the autophagosome elongation machinery (illustrated in Supplementary Fig. 2a) showed ATG16L1 to be preferentially enriched in the tumor epithelium when compared to ATG3, ATG4B, ATG5, ATG7, ATG10 and ATG12. ATG4A, ATG4C, and ATG4D were not detected, likely due to poor transcript coverage or low expression (Supplementary Fig. 2b). The gene discussed is ATG12; the disease is neoplasm.
