Genes affected

LHFPL5 (HGNC:21253): (LHFPL tetraspan subfamily member 5) This gene is a member of the lipoma HMGIC fusion partner (LHFP) gene family, which is a subset of the superfamily of tetraspan transmembrane protein encoding genes. Mutations in this gene result in deafness in humans, and a mutation in a similar gene in mice results in deafness and vestibular dysfunction with severe degeneration of the organ of Corti. It is proposed to function in hair bundle morphogenesis. [provided by RefSeq, Jul 2008]

The LHFPL5 c.494C>T variant is predicted to result in the amino acid substitution p.Thr165Met. This variant was reported in the homozygous state in six individuals from a consanguineous family with nonsyndromic hearing loss (Kalay. 2006. PubMed ID: 16752389). This variant is reported in 0.0096% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
