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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 11, 2013The Asp1143Val in LOXHD1 has not been reported in individuals with hearing loss or in large population studies. Computational analyses (biochemical amino acid p roperties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the varian t may impact the protein, though this information is not predictive enough to de termine pathogenicity. In summary, additional information is needed to fully ass ess the clinical significance of the Asp1143Val variant. -
