VDR and osteosarcoma: A functional study done inMG-63 human bone derived osteosarcoma cell line demonstrated that presence of mutant haplotype (G-C-T) is associated with 15% lower level of VDR mRNA expression and 30% faster decay of VDR mRNA compared to the wild haplotype (A-A-C) [14].The findings of our study were in concordance with these studies that showed association of mutant alleles of VDR gene (Taq1 rs731236 and Apa1 rs7975233) with developing dengue virus infection.
