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.Arg1586Leu variant in LOXHD1 has not been previously reported in individua ls with hearing loss. This variant has been identified in 1/2864 of African chro mosomes and in 1/9204 of European chromosomes by the Exome Aggregation Consortiu m (ExAC, http://exac.broadinstitute.org; dbSNP rs369890906); though this frequen cy is not high enough to rule out pathogenicity. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Arg1586Leu varia nt is uncertain. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.4757G>T (p.R1586L) alteration is located in exon 31 (coding exon 31) of the LOXHD1 gene. This alteration results from a G to T substitution at nucleotide position 4757, causing the arginine (R) at amino acid position 1586 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
