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. The gene discussed is VDR; the disease is dengue disease.
