FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The helix-loop-helix (HLH) proteins are a family of putative transcription factors, some of which have been shown to play an important role in growth and development of a wide variety of tissues and species. Four members of this family have been clearly implicated in tumorigenesis via their involvement in chromosomal translocations in lymphoid tumors: MYC (MIM 190080), LYL1 (MIM 151440), E2A (MIM 147141), and SCL (MIM 187040).[supplied by OMIM, Nov 2002]
PHENOTYPE: Homozygous targeted null mutants show cardiac arrhythmia and lack a heart rate response to water immersion. Adults are subject to sudden death, probably due to poor parasympathetic tone. Homozygotes for another targeted mutation had no abnormalities. [provided by MGI curators]
