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]

The c.484G>A (p.V162M) alteration is located in exon 6 (coding exon 4) of the LRTOMT gene. This alteration results from a G to A substitution at nucleotide position 484, causing the valine (V) at amino acid position 162 to be replaced by a methionine (M). Based on data from gnomAD, the A allele has an overall frequency of 0.004% (8/186856) total alleles studied. The highest observed frequency was 0.028% (7/25446) of Latino alleles. This amino acid position is not well conserved in available vertebrate species. This alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
