SORL1 is a member of the low-density lipoprotein receptor family [21] that has a potential biomarker role in patients with non-Hodgkin's lymphoma [34, 35], and GLT1D1 (glycosyltransferase 1 domain containing 1) has been reported to be a candidate oncogene in human colorectal cancers with microsatellite instability [24]. This evidence concerns the gene LDLR and colorectal cancer.
