Genes affected

HNF4A (HGNC:5024): (hepatocyte nuclear factor 4 alpha) The protein encoded by this gene is a nuclear transcription factor which binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor which regulates the expression of several hepatic genes. This gene may play a role in development of the liver, kidney, and intestines. Mutations in this gene have been associated with monogenic autosomal dominant non-insulin-dependent diabetes mellitus type I. Alternative splicing of this gene results in multiple transcript variants encoding several different isoforms. [provided by RefSeq, Apr 2012]

Potent mutations in HNF4A are associated with poor insulin secretion in response to hyperglycemia. Associated with MODY1. Patients initially respond well to sulfonylureas but eventually become insulin dependent. However, more evidence is required to ascertain the role of this particular variant rs199796094 in MODY, yet. -
