Abstract |
Maturity-onset diabetes of the young ( MODY) is a monogenic form of diabetes mellitus characterized by autosomal dominant inheritance, early age of onset (<25 years) and pancreatic beta-cell dysfunction. MODY is genetically heterogeneous with five different genes identified to date: hepatocyte nuclear factor-4 alpha (HNF-4 alpha) [ MODY1]; glucokinase [ MODY2]; hepatocyte nuclear factor-1 alpha (HNF-1 alpha) [ MODY3]; insulin promoter factor-1 (IPF-1) [ MODY4]; and hepatocyte nuclear factor-1 beta (HNF-1 beta) [MODY5]. Mutations in the HNF-1 alpha gene represent a common cause of MODY in the majority of populations studied. Sixty-five different mutations have been described in a total of 116 families. The most common mutation is a C-insertion (P291fsinsC) in the polyC tract of exon 4, which has been reported in 22 families. The identification of an HNF-1 alpha gene mutation in a patient with type 2 diabetes confirms the diagnosis of MODY and has important implications for clinical management.
