Vitamin D receptor poly(A) microsatellite and colorectal cancer risk in Caucasians.

Background Colorectal cancer incidence and prognosis are influenced by vitamin D intake and expression of the vitamin D receptor (VDR). Polymorphisms of the VDR are linked to several diseases. This study was aimed to investigate whether variants of the VDR poly(A) microsatellite are associated with colorectal cancer incidence.
