Genes affected
TOMT (HGNC:55527): (transmembrane O-methyltransferase) This gene encodes a catechol-O-methyltransferase that catalyzes the transfer of a methyl group from S-adenosyl-L-methionine to a hydroxyl group of catechols and is essential for auditory and vestibular function. Mutations in this gene have been associated with nonsyndromic deafness. Readthrough transcription is observed across this gene and the adjacent leucine-rich repeat containing 51 gene. A third locus (GeneID:220074) is defined to represent the readthrough transcripts. [provided by RefSeq, Feb 2021]

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 24, 2015p.Thr63Met in exon 5 of LRTOMT: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, 10 mammals have a methionine (Met) at this position despite high nearby am ino acid conservation. In addition, computational prediction tools do not sugges t a high likelihood of impact to the protein. -
