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]

TOMT links:

LRTOMT (HGNC:25033): (leucine rich transmembrane and O-methyltransferase domain containing) This locus represents naturally occurring readthrough transcription between the neighboring LRRC51 (leucine-rich repeat containing 51) and TOMT (transmembrane O-methyltransferase) genes on chromosome 11. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. Multiple reports implicate mutations in this gene in nonsyndromic deafness.[provided by RefSeq, Feb 2021]

Ile282Leu in exon 7 of LRTOMT: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Of no te, shrew, wallaby and opossum have a leucine (Leu) at this position despite hig h nearby amino acid conservation. In addition, computational analyses (PolyPhen2 , SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. -
