MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] MAFA is a transcription factor that binds RIPE3b, a conserved enhancer element that regulates pancreatic beta cell-specific expression of the insulin gene (INS; MIM 176730) (Olbrot et al., 2002 [PubMed 12011435]).[supplied by OMIM, Mar 2008]
PHENOTYPE: Homozygous mutant mice exhibit glucose intolerance and develop diabetes mellitus. Glucose-stimulated insulin secretion is severely impaired and mutant mice display pancreatic islet abnormalities as they age. [provided by MGI curators]
