| Research Abstract |
Vitamin D deficiency resulting in hypocalcemic seizures or rickets in children is increasing due to an insufficient intake of vitamin D and a lack of sunshine exposure. The prevalence of vitamin D deficiency is low compared to the large number of breastfed children with low serum levels of 25OHD. In this study, we analyzed the genetic predisposition for the onset of vitamin D deficiency. We analyzed polymorphisms in vitamin D related genes in patients with vitamin D deficiency and controls in Japan. We found differences in the polymorphisms or haplotype of VDR, GC, and NADSYN1 genes, suggesting that genetic factors may predispose to vitamin D deficiency to some extent. We further detected congenital rickets in some patients clinically presenting as vitamin D deficiency. Gene analysis may be very useful in the diagnosis of rickets.
