GC Glu416Asp and Thr420Lys polymorphisms contribute to gastrointestinal cancer susceptibility in a Chinese population.

ABSTRACT: Vitamin D has potent anticancer properties, especially against gastrointestinal cancers. Group-specific component (GC), a key member of vitamin D pathway proteins, could bind to and transport vitamin D to target organs. As a polymorphic protein, two common coding single nucleotide polymorphisms (SNP) [Glu416Asp (rs7041) and Thr420Lys (rs4588)] were identified in its gene. These SNPs have been associated to circulating vitamin D levels and several cancer risks in different populations. However, there is no report on their role in gastrointestinal cancer development among Chinese to date. Therefore, we examined the association between these variants and risk of gastrointestinal cancers in a case-control cohort including 964 patients with four gastrointestinal cancers (hepatocellular carcinom
