Abstract
Aim: In recent years, it is believed that Vitamin D may play a protective role in some
cancer types. Certain regions of the Vitamin D receptor (VDR) gene may show a genetic
difference in structure. The most frequent polymorphisms in this gene are in Taq-1,
Fok-1, and Bsm-1 regions. Some adult cancer types are associated with VDR gene polymorphism
such as; colorectal carcinoma, breast carcinoma, and prostate carcinoma. Reviewing
the medical literature, no such study had been done on children so far. Materials and Methods: We investigated the association of the three most common gene polymorphisms (Taq-1,
Fok-1, and Bsm-1 regions) in VDR gene in 32 children with brain tumors and forty control
healthy volunteers. Results: We could not find any relationship between childhood brain tumors and VDR gene polymorphism
in these three regions. Conclusion: The present results suggest that the Taq-1, Fok-1, and Bsm-1 polymorphism in the
VDR gene and pediatric brain cancers have no association.
