Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_001384474.1(LOXHD1):c.6268C>T(p.Arg2090Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000934 in 1,551,648 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R2090Q) has been classified as Likely benign.

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]

Variant classified as Uncertain Significance - Favor Benign. The p.Arg2028Trp va riant in LOXHD1 has not been previously reported in individuals with hearing los s, but has been identified in 0.2% (14/7914) of South Asian chromosomes by the E xome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs56934 1831). The arginine (Arg) at position 2028 is not highly conserved in mammals an d evolutionary distant species, and 1 mammal (David's myotis bat) carries a tryp tophan (Trp) at this position, raising the possibility that this change at this position may be tolerated. Additional computational prediction tools do not prov ide strong support for or against an impact to the protein. In summary, while th e clinical significance of the p.Arg2028Trp variant is uncertain, these data sug gest that it is more likely to be benign. -
