MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene includes two transcript forms. The short form has one open reading frame (ORF), which encodes the leucine-rich repeats (LRR)-containing protein of unknown function. This protein is called LRTOMT1 or LRRC51. The long form has two alternative ORFs; the upstream ORF has the same translation start codon as used in the short form and the resulting transcript is a candidate for nonsense-mediated decay, and the downstream ORF encodes a different protein, which is a transmembrane catechol-O-methyltransferase and is called LRTOMT2, TOMT or COMT2. The COMT2 is essential for auditory and vestibular function. Defects in the COMT2 can cause nonsyndromic deafness. Alternatively spliced transcript variants from each transcript form have been found for this gene. [provided by RefSeq, Sep 2012]
PHENOTYPE: Mice homozygous for a mutation of this gene exhibit marked hyperactivity, bidirectional circling and head-tossing. These behaviors are suppressed during sleep and nursing. Homozygous mutant males exhibit heightened male:male aggression. [provided by MGI curators]
