Genes affected

SYNE4 (HGNC:26703): (spectrin repeat containing nuclear envelope family member 4) This gene is a member of the nesprin family of genes, that encode KASH (Klarsicht, Anc-1, Syne Homology) domain-containing proteins. In addition to the KASH domain, this protein also contains a coiled-coil and leucine zipper region, a spectrin repeat, and a kinesin-1 binding region. This protein localizes to the outer nuclear membrane, and is part of the linker of nucleoskeleton and cytoskeleton (LINC) complex in the nuclear envelope. LINC complexes are formed by SUN (Sad1, UNC-84)-KASH pairs, and are thought to mechanically couple nuclear components to the cytoskeleton. Mutations in this gene have been associated with progressive high-frequency hearing loss. The absence of this protein in mice also caused hearing loss, and changes in hair cell morphology in the ears. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2015]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Leu206Leu variant in the SYNE3 gene has not been identified in individuals with hearing loss, but has been identified in 2/59604 European chromosomes by t he Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. This variant is located in the last three bases of the exon, which is part of the 5' splice region. Computational tools d o not suggest an impact to splicing. However, this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Leu206Leu variant is uncertain. -
