'''MODY 3''' is a form of [[Maturity onset diabetes of the young]] (MODY), which is a group of inherited forms of [[diabetes mellitus]]. It is caused by mutations in the [[HNF1A]] gene.
==Overview==
MODY 3 is the most common form of MODY. It is characterized by an onset usually before the age of 25, a primary defect in insulin secretion and a strong inheritance pattern. The disease is caused by mutations in the HNF1A gene, which encodes a transcription factor that regulates the expression of several liver-specific genes.
==Symptoms==
The symptoms of MODY 3 are similar to those of other forms of diabetes, including frequent urination, excessive thirst, fatigue, blurred vision, and weight loss. However, MODY 3 often goes undiagnosed because the symptoms are mild or absent.
==Diagnosis==
The diagnosis of MODY 3 is based on clinical features and genetic testing. The presence of diabetes in multiple generations, the onset of diabetes at a young age, and the absence of obesity or other risk factors for type 2 diabetes suggest the diagnosis of MODY 3.
==Treatment==
The treatment of MODY 3 involves lifestyle modifications and medication. Patients with MODY 3 often respond well to low doses of sulfonylureas, which stimulate the release of insulin from the pancreas.
==Prognosis==
The prognosis of MODY 3 is generally good, but patients are at risk for long-term complications of diabetes, including heart disease, kidney disease, and eye disease.
