NR3C1 and cancer: The most statistically significant CIS was in the Nr3c1 gene, which encodes the glucocorticoid receptor (GR), and the insertions would be predicted to have a loss-of-function effect on Nr3c1, consistent with the finding of promoter hypermethylation or mono-allelic deletion of NR3C1 in several cancer types including colo-rectal cancer (CRC)[15] and leukemia[16], respectively.
