Abstract
We have recently described a mitochondrial DNA (mtDNA) point mutation at np 3243 in the tRNA(Leu)(UUR) gene in a large Dutch pedigree with maternally inherited diabetes mellitus and deafness (MIDD) illustrating the importance of mitochondrial function in maintenance of a proper glucose homeostasis. In this review we will focus on the prevalence of the mtDNA mutation at np 3243 in diabetic populations, as well as postulate some working models for its pathogenicity.
