Mitochondrial diabetes: pathophysiology, clinical presentation, and genetic analysis.

Abstract excerpt

This study provides a compact overview on the most common form of the maternally inherited diabetes and deafness syndrome (MIDD) that associates with an A-G mutation in mitochondrial DNA at position 3243 in the tRNA(Leu,UUR) gene. The pathobiochemistry and pathophysiology is discussed. The mutation leads predominantly to a reduced insulin secretion by beta cells in response to glucose stimulation, however,...
