Genes affected

USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

The p.Glu3912Lys variant in USH2A has not been previously reported in individual s with hearing loss, but has been identified in 20/124246 European chromosomes b y the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbS NP rs142617606). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational pr ediction tools and conservation analyses do not provide strong support for or ag ainst an impact to the protein. In summary, the clinical significance of the p.G lu3912Lys variant is uncertain. -

The c.11734G>A (p.E3912K) alteration is located in exon 61 (coding exon 60) of the USH2A gene. This alteration results from a G to A substitution at nucleotide position 11734, causing the glutamic acid (E) at amino acid position 3912 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
