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 c.710A>G (p.N237S) alteration is located in exon 6 (coding exon 6) of the LOXHD1 gene. This alteration results from a A to G substitution at nucleotide position 710, causing the asparagine (N) at amino acid position 237 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Asn237Ser in exon 6 of LOXHD1: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Of no te, several species including three mammals have a serine (Ser) at this position despite high nearby amino acid conservation. In addition, computational predict ion tools do not suggest a high likelihood of impact to the protein. -
