GALC and inflammatory bowel disease: Genomic DNA from a group of 547 patients with IBD (mean age 55.7 years, range 20–81) and 591 non-IBD subjects (mean age 42.6 years, range 16–82) was used to genotype individuals for genetic variants rs8005161 [13, 14], rs3742704 [12, 13] (both assigned to the GPR65 gene), and an additional neighbouring SNP rs1805078 (galactosylceramidase, GALC).
