MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene and the orthologous mouse gene were found by their homology to the Drosophila lady bird early and late homeobox genes. In the mouse, this gene is a key regulator of muscle precursor cell migration and is required for the acquisition of dorsal identities of forelimb muscles. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice display impaired limb muscle development resulting from progenitor cell migration defects. Defects in heart development and nervous system morphology are also reported. [provided by MGI curators]
