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.Gly1710Arg variant in LOXHD1 has not been previously reported in individua ls with hearing loss and data from large population studies are insufficient to assess the frequency of this variant in the general population. Computational pr ediction tools and conservation analysis suggest that the p.Gly1710Arg variant m ay impact the protein, though this information is not predictive enough to deter mine pathogenicity. In summary, the clinical significance of the p.Gly1710Arg va riant is uncertain. -
