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]

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 158 of the LHFPL5 protein (p.Arg158Trp). This variant is present in population databases (rs753739358, gnomAD 0.01%). This missense change has been observed in individual(s) with deafness (PMID: 30298622). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 505548). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. -

Variant classified as Uncertain Significance - Favor Pathogenic. The p.Arg158Trp variant in LHFPL5 has been previously reported in the homozygous state in an in dividual with congenital profound sensorineural hearing loss from a consanguineo us Arab family (Komara 2016). This variant has also been identified in 8/126732 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.b roadinstitute.org; dbSNP rs753739358). Although this variant has been seen in th e general population, its frequency is low enough to be consistent with the carr ier frequency for autosomal recessive hearing loss. However, population data spe cific for Arab populations are not available. Computational prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary , while there is some suspicion for a pathogenic role, the clinical significance of the p.Arg158Trp variant is uncertain. -
