Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000824784 SCV000245680 pathogenic Rare genetic deafness 2016-01-27 criteria provided, single submitter clinical testing The p.Cys3358Tyr variant in USH2A has been reported in over 10 individuals with retinitis pigmentosa, with at least five of these individuals being compound het erozygous for a pathogenic variant on the remaining copy of USH2A (Garcia-Garcia 2011, LeQuesne Stabej 2012, Lenassi 2015, McGee 2010, Neveling 2012, van Huet 2 015, Wang 2014, Zhao 2015, Avila-Fernandez 2010). Two of these individuals were reported to have features of atypical type 2 Usher syndrome, with a later onset hearing loss (Garcia-Garcia 2011, Lenassi 2015). The variant has been identifie d in 33/66704 European chromosomes by the Exome Aggregation Consortium (ExAC, ht tp://; dbSNP rs148660051); however its frequency is low e nough to be consistent with a recessive carrier frequency. Computational predict ion tools and conservation analysis suggest an impact to the protein. In summary , this variant meets our criteria to be classified as pathogenic for autosomal r ecessive retinitis pigmentosa and/or atypical type 2 Usher syndrome, based on th e previously reported individuals.
Knight Diagnostic Laboratories, Oregon Health and Sciences University RCV000190637 SCV000538073 likely pathogenic Usher syndrome, type 2A 2016-01-27 criteria provided, single submitter clinical testing The c.10073G>A (p.Cys3358Tyr) missense variant in the USH2A gene has been previously reported in several individuals affected with Usher Syndrome or Retinitis Pigmentosa. This allele was observed in 13 cases out of 914 affected alleles (Lenassi et al., 2015) and is significantly higher than the allele frequency in the ExAC database (13/121292). This variant is often seen in trans with other pathogenic variants (Garcia-Garcia et al., 2011; Le Quesne Stabej et al., 2012; Neveling et al., 2012; Lenassi et al., 2015). This c.10073G>A allele has been reported at low frequency, or is absent in other population databases (Exome Sequencing Project [ESP] = 0.058%, 1000 Genomes = NA). Multiple in silico algorithms predict this variant to have a deleterious effect GERP = 5.76; CADD = 22.4; PolyPhen = 1; SIFT = 0). Reputable diagnostic laboratories have reported this variant as either Likely Pathogenic or Pathogenic for either, Retinitis Pigmentosa or Usher Syndrome, Type 2A. Therefore, this collective evidence supports the classification of the c.10073G>A (p.Cys3358Tyr) as a recessive Likely Pathogenic variant for Usher syndrome, type IIA.
GeneDx RCV000482080 SCV000565648 pathogenic not provided 2018-11-02 criteria provided, single submitter clinical testing The C3358Y variant in the USH2A gene has been reported previously in association with non-syndromic retinitis pigmentosa. Affected individuals were heterozygous for the C3358Y variant in addition to harboring a second variant in the USH2A gene (Avila-Fernandez et al., 2010; Neveling et al., 2012; Le Quesne Stabej et al., 2012; Zhao et al., 2015; Lenassi et al., 2015). The C3358Y variant is observed in 94/126,370 (0.0744%) alleles from individuals of non-Finnish European background in large population cohorts, with no homozygous control individuals reported (Lek et al., 2016). The C3358Y variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In addition, in silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. We interpret C3358Y as a pathogenic variant.

SIB Swiss Institute of Bioinformatics RCV000179099 SCV000803576 likely pathogenic Retinitis pigmentosa 39 2018-05-31 criteria provided, single submitter curation This variant is interpreted as a Likely Pathogenic, for Retinitis pigmentosa 39, in Autosomal Recessive manner. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM3-Strong => PM3 upgraded in strength to Strong (PMID:22334370) (PMID:25649381).
Invitae RCV000482080 SCV000952339 pathogenic not provided 2020-01-06 criteria provided, single submitter clinical testing This sequence change replaces cysteine with tyrosine at codon 3358 of the USH2A protein (p.Cys3358Tyr). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is present in population databases (rs148660051, ExAC 0.05%). This variant has been observed in individual(s) with Usher syndrome or retinal disease (PMID: 22004887, 28559085, 22135276, 25472526). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 197932). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. For these reasons, this variant has been classified as Pathogenic.
Myriad Women's Health, Inc. RCV000190637 SCV001193786 likely pathogenic Usher syndrome, type 2A 2019-12-17 criteria provided, single submitter clinical testing NM_206933.2(USH2A):c.10073G>A(C3358Y) is classified as likely pathogenic in the context of USH2A-related disorders and is primarily associated with retinitis pigmentosa. Sources cited for classification include the following: PMID 22004887, 22334370, 26667666, 25472526, 25097241, 25649381 and 20507924. Classification of NM_206933.2(USH2A):c.10073G>A(C3358Y) is based on the following criteria: This variant has been observed more frequently in patients with clinical diagnoses than in healthy populations. Please note: this variant was assessed in the context of healthy population screening.

Integrated Genetics/Laboratory Corporation of America RCV001174974 SCV001338457 likely pathogenic Usher syndrome 2020-04-09 criteria provided, single submitter clinical testing Variant summary: USH2A c.10073G>A (p.Cys3358Tyr) results in a non-conservative amino acid change located in the Fibronectin type III domain (IPR003961) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00035 in 251094 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in USH2A causing Usher syndrome (0.00035 vs 0.013), allowing no conclusion about variant significance. c.10073G>A has been reported in the literature in individuals affected with Usher syndrome and other USH2A related diseases (e.g. Garcia-Garcia_2011, LeQuesneStabej_2012, Lenassi_2015, Calzetti_2018). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Twelve ClinVar submitters (evaluation after 2014) cite the variant as likely pathogenic (n= 9) and pathogenic (n=3). Based on the evidence outlined above, the variant was classified as likely pathogenic.
