Genes affected

SLC17A8 (HGNC:20151): (solute carrier family 17 member 8) This gene encodes a vesicular glutamate transporter. The encoded protein transports the neurotransmitter glutamate into synaptic vesicles before it is released into the synaptic cleft. Mutations in this gene are the cause of autosomal-dominant nonsyndromic type 25 deafness. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

The Gly183Arg variant in SLC17A8 has not been reported in individuals with heari ng loss but has been identified in 0.02% (2/8600) of European American chromosom es by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbS NP rs150737570). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational an alyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, a nd SIFT) do not provide strong support for or against an impact to the protein. In summary, additional data is needed to determine the clinical significance of this variant. -
