MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This intronless gene encodes a helix-loop-helix protein. Translocations between this gene on chromosome 9 and the T-cell receptor beta-chain locus on chromosome 7 have been associated with activation of the T-cell acute lymphocytic leukemia 2 gene and T-cell acute lymphoblastic leukemia. [provided by RefSeq, Mar 2009]
PHENOTYPE: Homozygous mutation of this gene results in growth retardation and lethality before reaching reproductive age. Mice exhibit brain abnormalities including a small superior colliculus and progressive hydrocephalus. [provided by MGI curators]
