MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene belongs to the basic helix-loop-helix family of transcription factors. This gene product is one of two closely related family members, the HAND proteins, which are asymmetrically expressed in the developing ventricular chambers and play an essential role in cardiac morphogenesis. Working in a complementary fashion, they function in the formation of the right ventricle and aortic arch arteries, implicating them as mediators of congenital heart disease. In addition, it has been suggested that this transcription factor may be required for early trophoblast differentiation. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for targeted null mutations die at embryonic day 8.5-9.5 with yolk sac abnormalities associated with a deficiency of extraembryonic mesoderm and defective trophoblast differentiation. Tetraploid chimeric rescue slightly extends development. [provided by MGI curators]
