Disease

HNF4A_HUMAN Defects in HNF4A are the cause of maturity-onset diabetes of the young type 1 (MODY1) [MIM:125850; also symbolized MODY-1. MODY is a form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease.^[1] ^[2] ^[3]

Function

HNF4A_HUMAN Transcriptionally controlled transcription factor. Binds to DNA sites required for the transcription of alpha 1-antitrypsin, apolipoprotein CIII, transthyretin genes and HNF1-alpha. May be essential for development of the liver, kidney and intestine.
