“…It is characterized by a reduction in BMD. As an active component of this system, therefore, polymorphisms in the OPG gene might influence bone metabolism and BMD (Wang et al, 2013;Guo et al, 2014) neck hip and total hip was determined by dual-energy X-ray absorptiometry (DEXA). Although several studies have investigated the association of OPG single nucleotide polymorphisms (SNPs) such as 163A>G, 1181G>C, 245T>G, and 950T>C with BMD and bone disorders (Feng et al, 2012;Liu et al, 2013;Wang et al, 2013;Yu et al, 2013;Guo et al, 2014) which is characterized by a decrease in BMD, the relationship between the 1181G>C and 163A>G SNPs of the OPG gene and T1DM and BMD has not yet been evaluated.…”
