Our eQTL analysis indicated that the rs7935113-C risk allele leads to an increased expression of GALNTL4. This is consistent with previous data which found various genes encoding GALNAC-Ts to be overexpressed in malignant tissues compared with normal tissue, such as GALNT3 in pancreatic cancer and GALNT6 in breast cancer14, 15. Here, GALNT18 is linked to familial pancreatic carcinoma.
