Abstract

Uncoupling protein 2 (UCP2) is a member of the mitochondrial proton transport family that uncouples proton entry to the mitochondria from ATP synthesis. UCP2 expression levels have been linked to predisposition to diabetes and obesity. In addition, UCP2 prevents neuronal death and injury. Here we show that the common −866G/A promoter polymorphism is associated with susceptibility to multiple sclerosis (MS) in the German population. We analysed altogether 1,097 MS patients and 462 control subjects from two cohorts and found that the common G allele is associated with disease susceptibility (p=0.0015). The UCP2 −866G allele is correlated with lower levels of UCP2 expression as shown here in vitro and in vivo. Thus, UCP2 promoter polymorphism may contribute to MS susceptibility by regulating the level of UCP2 protein in the central nervous and/or the immune systems.
