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

The p.Ala59Glu variant in LHFPL5 has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tool s and conservation analyses suggest that the p.Ala59Glu variant may impact the p rotein, though this information is not predictive enough to determine pathogenic ity. In summary, the clinical significance of the p.Ala59Glu variant is uncertai n. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.176C>A (p.A59E) alteration is located in exon 1 (coding exon 1) of the LHFPL5 gene. This alteration results from a C to A substitution at nucleotide position 176, causing the alanine (A) at amino acid position 59 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
