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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 159 of the LHFPL5 protein (p.Arg159His). This variant is present in population databases (rs139179263, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with LHFPL5-related conditions. ClinVar contains an entry for this variant (Variation ID: 163857). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.Arg159His var iant in LHFPL5 has been reported in 1 individual with hearing loss by our labora tory (LMM unpublished data), but has been identified in 0.17% of African chromos omes by the genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.or g; dbSNP rs139179263). This variant has also been reported in ClinVar (Variation ID 163857). Computational prediction tools and conservation analyses suggest th at this variant may impact the protein, though this information is not predictiv e enough to determine pathogenicity. In summary, while the clinical significance of the p.Arg159His variant is uncertain, population data suggest that it is mor e likely to be benign. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.476G>A (p.R159H) alteration is located in exon 2 (coding exon 2) of the LHFPL5 gene. This alteration results from a G to A substitution at nucleotide position 476, causing the arginine (R) at amino acid position 159 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
