Summary
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]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (4) represents the long transcript form. It has multiple differences from variant 1. This variant lacks the upstream open reading frame as seen in the other variants of the long transcript form. The encoded isoform (LRTOMT2a) is a transmembrane catechol-O-methyltransferase. This protein is supported by Western blot as reported in PMID:18953341. Variants 4 and 5 encode the same isoform LRTOMT2a.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (5, also known as D') represents the long transcript form. It lacks the 3' terminal exon and includes several alternate exons, compared to variant 1. This variant encodes isoform LRTOMT2a, which is a transmembrane catechol-O-methyltransferase and is supported by Western blot as reported in PMID: 18953341. Variants 4 and 5 encode the same isoform LRTOMT2a.

    Description
    Transcript Variant: This variant (6, also known as E') represents the long transcript form. It lacks the 3' terminal exon and includes several alternate exons, compared to variant 1. This variant encodes isoform LRTOMT2b, which lacks an internal segment including the transmembrane region, compared to isoform LRTOMT2a. Isoform LRTOMT2b is a catechol-O-methyltransferase, which is supported by Western blot as reported in PMID: 18953341.
