Genes affected
LRRC51 (HGNC:55526): (leucine rich repeat containing 51) This gene belongs to the leucine-rich repeat containing family. The encoded protein contains a transmembrane domain and two leucine-rich repeat domains. Unlike in mouse and other mammals, readthrough transcription is observed in primates between this gene and the adjacent transmembrane O-methyltransferase (Tomt) gene. Previously, this locus was annotated as a single gene representing the readthrough transcripts as well as the two different transcript species that encoded different proteins. It has since been split into three genes, including the two stand-alone genes and a third gene representing the readthrough transcription. [provided by RefSeq, Feb 2022]

Autosomal recessive nonsyndromic hearing loss 63 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 12, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
