Maturity-onset diabetes of the young (MODY) is an autosomal dominantly inherited type of diabetes that results from heterozygous mutations in various transcription factors acting in the development and maturation of pancreatic β-cells. In addition, mutations in enzymes involved in glucose sensing of the β-cell have also been shown to result in early-onset diabetes. Characteristic features of MODY are autosomal inheritance, early onset of diabetes (with diagnosis generally before the age of 25 years), no signs related to the autoimmune process or insulin resistance, and preservation of endogenous insulin secretion.
