(C;T) 3.6 Mature onset diabetes of the young (type 3)

This is a genotype with recommended actions if clinically confirmed. In brief:

  • Maturity Onset Diabetes of the Young Type III (MODY) is a form of familial diabetes characterized by an early age of onset and by impaired insulin secretion with little or no defects in insulin action.
  • Annual screening for diabetes in asymptomatic mutation carriers is recommended from the age of 10.
  • Persons who are positive for an HNF1A gene mutation and who develop clinical symptoms can initially be treated with diet. With progressive deterioration in glycemic control, low-dose sulfonylureas are recommended as the first-line treatment.
  • Patients with MODY3 are at risk of vascular complications and cardiovascular disease. Thus statin therapy is recommended by age 40, regardless of lipid status.
