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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Asp285Gly variant in LOXHD1 has not been previously reported in individual s with hearing loss. Data from large population studies is insufficient to asse ss the frequency of this variant. Computational prediction tools and conservatio n analyses do not provide strong support for or against an impact to the protein . In summary, the clinical significance of the p.Asp285Gly variant is uncertain. -

Collection Method: clinical testing

The c.854A>G (p.D285G) alteration is located in exon 7 (coding exon 7) of the LOXHD1 gene. This alteration results from a A to G substitution at nucleotide position 854, causing the aspartic acid (D) at amino acid position 285 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
