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 a member of the NKL homeobox family of transcription factors. Members in this family are of ancient origin and play an important role in organ development during embryogenesis. A related mouse protein plays a role in patterning of inner ear structures. In humans, variations in a region containing this gene have been associated with inner ear malformations, vestibular dysfunction, and hearing loss. [provided by RefSeq, Aug 2012]
PHENOTYPE: Homozygous disruption of this gene results behavioral abnormalities, such as hyperactivity, head tilting and circling, as well as abnormal vestibular morphogenesis, including severe dysgenesis of all three semicircular ducts. [provided by MGI curators]
