MODY 1 (Maturity Onset Diabetes of the Young type 1) is a form of monogenic diabetes that is characterized by an autosomal dominant inheritance pattern. It is one of the several types of MODY, which are caused by mutations in a single gene that affect insulin production or secretion.
Genetic Basis[edit]
MODY 1 is caused by mutations in the HNF4A gene, which encodes the hepatocyte nuclear factor 4 alpha. This gene plays a crucial role in the regulation of insulin secretion and glucose metabolism. The mutation leads to impaired insulin secretion, resulting in hyperglycemia.
Clinical Features[edit]
Patients with MODY 1 typically present with mild to moderate hyperglycemia at a young age, often before the age of 25. Unlike type 1 diabetes, MODY 1 does not usually require insulin therapy initially, and patients may be managed with oral hypoglycemic agents.
Diagnosis[edit]
The diagnosis of MODY 1 is confirmed through genetic testing, which identifies mutations in the HNF4A gene. Family history is also an important factor, as MODY 1 follows an autosomal dominant pattern, meaning that a single copy of the mutated gene can cause the disorder.
Management[edit]
Management of MODY 1 involves lifestyle modifications, such as diet and exercise, and the use of oral hypoglycemic agents like sulfonylureas. In some cases, insulin therapy may be required as the disease progresses.
