MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is an SP family transcription factor that in mouse has been shown to be essential for proper limb development. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2011]
PHENOTYPE: Homozygous mutant fetuses are characterized by truncated limbs, the lack of a tail, and neural tube defects. [provided by MGI curators]
