This gene encodes two different proteins. One is a leucine-rich transmembrane protein of unknown function while the other is an O-methyltransferase. Defects in the O-methyltransferase protein can cause nonsyndromic deafness. Several transcript variants encoding different isoforms of each protein have been found for this gene.
