Genes affected
LOXHD1 (HGNC:26521): (lipoxygenase homology PLAT domains 1) This gene encodes a highly conserved protein consisting entirely of PLAT (polycystin/lipoxygenase/alpha-toxin) domains, thought to be involved in targeting proteins to the plasma membrane. Studies in mice show that this gene is expressed in the mechanosensory hair cells in the inner ear, and mutations in this gene lead to auditory defects, indicating that this gene is essential for normal hair cell function. Screening of human families segregating deafness identified a mutation in this gene which causes DFNB77, a progressive form of autosomal-recessive nonsyndromic hearing loss (ARNSHL). Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Mar 2010]

The p.Val638Met variant in LOXHD1 has not been previously reported in individual s with hearing loss and was absent from large population studies. Computational prediction tools and conservation analyses suggest that the p.Val638Met variant may impact the protein, though this information is not predictive enough to dete rmine pathogenicity. In summary, the clinical significance of the p.Val638Met va riant is uncertain. -
