Abstractdc.description.abstractSeveral reports have found a relation between polymorphisms of the vitamin D receptor gene (VDR) and the development of type I diabetes. We have examined the association of three VDR polymorphism with type I diabetes in 59 Chilean case-parents trios. Genotyping for Bsml, Apal and Taq1 polymorphism were performed. Transmission/ disequilbrium tests were used to assess gene-disease associations through the evaluation of allelic transmission to affected offspring. Non-significant increased transmissions of B allele (probability of transmission = 52.5%, p = 0.69), A allele (probability of transmission = 58.4%, p = 0.17) and T allele (probability of transmission = 52.0%, p = 0.77) were estimated in Bsm1, Apa1 and Taq1 sites, respectively. Haplotype-based analyses showed non-significant preferential transmissions (global p = 0.52). The present study does not support the hypothesis of a significant contribution of VDR alleles in the etiology of type I diabetes of Chilean cases.en
