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]

Variant classified as Uncertain Significance - Favor Benign. The Val1364Leu vari ant in LOXHD1 has not been reported in individuals with hearing loss, but has be en identified in 2/178 (1%) Japanese chromosomes by the 1000 Genomes Project (db SNP rs144935513). Although this variant has been seen in the general population, the sample size is not large enough to rule out a pathogenic role. Computationa l analyses (biochemical amino acid properties, conservation, AlignGVGD, and SIFT ) suggest that the variant may not impact the protein, though this information i s not predictive enough to rule out pathogenicity. In summary, the clinical sign ificance of this variant cannot be determined with certainty; however, based upo n its presence in the general population and the computational data, we lean tow ards a more likely benign role. -
