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.

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 3448 of the USH2A protein (p.Glu3448Lys). This variant is present in population databases (rs368049814, gnomAD 0.008%). This missense change has been observed in individual(s) with retinitis pigmentosa (PMID: 24265693, 26667666, 28761320, 28981474). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 209203). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on USH2A protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

The USH2A c.10342G>A variant was identified in an individual with retinitis pigmentosa with a presumed recessive inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PS1, PM2, PP3. Based on this evidence we have classified this variant as Likely Pathogenic. -

Variant summary: USH2A c.10342G>A (p.Glu3448Lys) results in a conservative amino acid change located in the Fibronectin type III domain (IPR003961) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.6e-05 in 251302 control chromosomes (gnomAD). c.10342G>A has been reported in the literature in multiple compound heterozygous and homozygous individuals affected with Retinitis Pigmentosa and Usher Syndrome (example: McGee_2011, Eisenberger_2013, Iglesias_2014, Maranhao_2014, Comander_2017, Jones_2017, Gao_2021). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Eleven ClinVar submitters have assessed the variant since 2014: seven have classified it as likely pathogenic and four as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
