FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of members of the mucolipin cation channel proteins. Mutation studies of the highly similar protein in mice have shown that the protein is found in cochlea hair cells, and mutant mice show early-onset hearing loss and balance problems. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]
PHENOTYPE: Heterozygotes show normal/diluted/white hair patches, circling, hyperactivity, deafness, and reduced fertility. Homozygotes are white with small patches of color and show severe behavioral abnormalities, poor postnatal viability and are nearly infertile. [provided by MGI curators]
