Pathogenic, criteria provided, single submitterclinical testingInvitaeNov 01, 2022This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 759 of the USH2A protein (p.Cys759Phe). This variant is present in population databases (rs80338902, gnomAD 0.2%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individuals with autosomal recessive isolated retinitis pigmentosa and USH2A-related disorders (PMID: 10775529, 12525556, 15325563, 25649381, 25910913, 28041643). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 2356). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt USH2A protein function. For these reasons, this variant has been classified as Pathogenic. -

Likely pathogenic, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesJan 10, 2020The USH2A c.2276G>T; p.Cys759Phe variant (rs80338902) is reported in the medical literature in the homozygous or compound heterozygous state in individuals with retinal disease (Bernal 2003, Carss 2017, Lenassi 2015, Seyedahmadi 2004) and is reported to segregate with disease (Rivolta 2000). The variant is reported to occur at an increased frequency compared to control individuals (Seyedahmadi 2004). However, the variant was also detected in two unaffected individuals in the homozygous state (Bernal 2003). The variant is reported as pathogenic or likely pathogenic for Usher-related disease by several sources in the ClinVar database (Variation ID: 2356); however, the variant was recently classified as a variant of uncertain significance for hearing loss based on an expert panel curation (Azaiez 2018). The variant is reported in the general population with an overall allele frequency of 0.097% (273/282,114 alleles) in the Genome Aggregation Database. The cysteine at codon 759 is moderately conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Considering available information, this variant is classified as likely pathogenic. References: Azaiez H et al. Genomic Landscape and Mutational Signatures of Deafness-Associated Genes.

Retinitis pigmentosa 39 Pathogenic:9
Pathogenic, criteria provided, single submitterclinical testingVictorian Clinical Genetics Services, Murdoch Childrens Research InstituteMay 21, 2020A heterozygous missense variant was identified, NM_206933.3(USH2A):c.2276G>T in exon 13 of 72 of the USH2A gene. This substitution is predicted to create a major amino acid change from cysteine to phenylalanine at position 759 of the protein, NP_996816.2(USH2A):p.(Cys759Phe). The cysteine at this position has high conservation (100 vertebrates, UCSC), and is located within the Laminin EGF-like 5 domain. In silico software predicts this variant to be disease causing (Polyphen, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD population database at a frequency of 0.097% (273 heterozygotes, 0 homozygotes). The variant has been previously described as pathogenic and segregated with disease in multiple families with retinitis pigmentosa and Usher syndrome (ClinVar, Pérez-Carro, R. et al . (2018)). Based on information available at the time of curation, this variant has been classified as PATHOGENIC. Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign -

Pathogenic, criteria provided, single submitterclinical testing3billionSep 01, 2022The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.097%). While this variant results in missense change, protein truncation variants are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.90). The variant has been observed in multiple (>3) similarly affected unrelated individuals (PMID: 10909849 , 12112664 , 12525556 , 14970843 , 15325563 , 16098008 , 17405132 , 18273898 , 19683999 , 21151602 , 21738395 , 22004887 , 22135276 , 22334370 , 23591405 , 24944099 , 25097241 , 25261458 , 25262649 , 25375654 , 25649381 , 25823529 , 25910913 , 26764160 , 28041643 , 29283788 , 29588463). The variant has been reported to co-segregate with the disease in at least 5 similarly affected relatives/individuals in the same family or similarly affected unrelated family (PMID: 29912909). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpNov 26, 2019Variant summary: USH2A c.2276G>T (p.Cys759Phe) results in a non-conservative amino acid change located in the Laminin EGF-like 5 domain of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00097 in 250722 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in USH2A causing Usher syndrome (0.00097 vs 0.013), allowing no conclusion about variant significance. c.2276G>T has been reported in the literature in multiple individuals affected with nonsyndromic RP, Usher Syndrome and atypical Usher syndrome (e.g. Rivolta_2000, Aller_2004). 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. Twelve ClinVar submissions (evaluation after 2014) cite the variant eight times as pathogenic and four times as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineFeb 14, 2018The p.Cys759Phe variant in USH2A is a common pathogenic variant reported in 21 i ndividuals with Usher syndrome and 90 individuals with isolated recessive retini tis pigmentosa (Rivolta 2000, Dreyer 2000, Najera 2002, Rivolta 2002, Bernal 200 3, Aller 2004, Seyedahmadi 2004, Bernal 2005, Baux 2007, Dreyer 2008, Sandberg 2 008, Avila-Fernandez 2010, Vozzi 2011). It has also been identified in 0.1% (67/ 66700) of European chromosomes and 0.2% (22/11552) Latino chromosomes by the Exo me Aggregation Consortium (http://exac.broadinstitute.org/; dbSNP rs80338902); h owever, this frequency is consistent with a recessive carrier frequency. Additio nally, this variant is commonly seen with a second pathogenic allele and is obse rved to cosegregate with disease in affected family members. In summary, this va riant meets our criteria to be classified as pathogenic for Usher syndrome type IIA and retinitis pigmentosa both in an autosomal recessive manner. -
Pathogenic, reviewed by expert panelcurationClinGen Hearing Loss Variant Curation Expert PanelJul 28, 2019The p.Cys759Phe variant in USH2A has been reported in 10 individuals with a clinical diagnosis of Usher Syndrome type II who were all confirmed compound heterozygous with a second pathogenic variant on the remaining allele (PMIDs: 16098008, 24944099, 29912909) (PM3_Strong). Note that scoring for PM3 was downgraded from PM3_VeryStrong to PM3_Strong since this variant has an allele frequency that meets criteria for BS1 (see below). Co-segregation with Usher II was demonstrated collectively in 2 affected and 13 unaffected siblings (LOD score: 2.23). When including all families affected with Usher II or an atypical Usher presentation (retinitis pigmentosa (RP) with some form of hearing loss), co-segregation can be identified in three affected and 26 unaffected siblings total (LOD score: 4.45) (PMID: 29912909) (PP1_Strong). When considering those patients who present with isolated RP, the variant segregated in an additional 15 affected and 32 unaffected siblings (LOD score: 12.43) (PMIDs:10775529, 12525556, 21151602, 29912909). The filtering allele frequency (the lower threshold of the 95% CI of 72/35410) of the p.Cys759Phe variant in the Latino population in gnomAD is 0.17% and it has also been observed at the filtering allele frequency (the lower threshold of the 95% CI of 17/2536) of 0.43% across several Spanish or Latino populations published in the literature (PMIDs: 12525556, 12112664, 25262649, 26764160, 25261458, 25823529; BS1). Although this allele frequency meets the threshold defined by the ClinGen Hearing Loss Expert Panel for considering strong evidence against pathogenicity for autosomal recessive hearing loss variants, other studies suggest it may still be associated with Usher syndrome, albeit with potentially reduced penetrance. The variant is statistically enriched in cohorts of Usher (2.00% (54/2704) in Usher patients compared to 0.67% (17/2536) as the highest and most ethnically matched published Spanish and Latino control populations; Fisher's exact p value <0.0001) and RP patients (1.87% (109/5828) in RP patients compared to 0.71% in published Spanish and Latino controls; Chi-Square p value <0.0001) (PMIDs: 12525556, 12112664, 25262649, 26764160, 25261458, 25823529, 10909849, 12112664, 14970843, 15325563, 16098008, 17405132, 18273898, 19683999, 22004887, 21738395, 24944099, 25375654, 28041643, 29588463, 21151602, 25097241, 23591405, 25910913, 25649381, 29283788, 22135276, 22334370) (PS4). The association with Usher syndrome is particularly clear when paired with a predicted loss-of-function or other pathogenic variant compared to homozygous individuals who are more at risk to develop non-syndromic RP (PMIDs: 29912909 and 25375654). There may also be evidence of reduced penetrance for both hearing loss and RP as two homozygous individuals were documented to have no evidence of any phenotype through their 6th decade (PMIDs: 16098008, 12525556). The PP4 rule has also been applied to this variant given the combination of hearing loss and RP that is seen in these patients and that most patients were screened for other Usher genes. Lastly, computational prediction tools and conservation analysis suggest that the p.Cys759Phe variant may impact the protein (REVEL: 0.902), and an analysis using the homologous mouse laminin gamma 1 chain concluded that this variant is likely to disrupt disulfide bonding with the cysteine at position 747 (PMID: 10909849) (PP3). In summary, the ClinGen Hearing Loss Expert Panel believes that the evidence for the pathogenicity of this variant for Usher Syndrome outweighs its higher than expected allele frequency in population databases and other general population cohorts. Therefore, the BS1 code will not contribute to the overall classification. In summary, this variant meets criteria to be classified as pathogenic for Usher syndrome (ACMG codes applied: BS1, PS4, PM3_Strong, PP1_Strong, PP4, and PP3). Please note that patients with this variant may present with either Usher syndrome or w -

Pathogenic, criteria provided, single submitterclinical testingGenetics and Molecular Pathology, SA PathologyApr 15, 2021The USH2A c.2276G>T variant is classified as Pathogenic (PS4, PM3_Strong, PP1, PP3) The USH2A c.2276G>T variant is a single nucleotide change in the USH2A gene, which is predicted to change the amino acid cysteine at position 759 in the protein to phenylalanine. The variant has been reported in probands with a clinical presentation of Retinal dystrophy (PS4). PMID: 29912909. This variant segregates with disease in multiple unrelated families with Usher syndrome type II and non-syndromic ARRP (Pérez-Carro et al., 2018, PMID:29912909, Rivolta et al., 2000, PMID:10775529, Bernal at al, 2003, PMID:12525556, Ávila-Fernández et al., 2010, PMID:21151602) (PP1). This variant has been detected in trans with a pathogenic variant for this recessive condition (PM3). Computational predictions support a deleterious effect on the gene or gene product (PP3). Cysteine at position 759 is highly conserved (PhyloP=5.53) located in the EGF-like, laminin domain. Substitution with Phenylalanine is a non-conservative change (Grantham Score =205). Computational analysis predicts this change is damaging (CADD=33, SIFT=Deleterious). The variant has been reported in dbSNP (rs80338902) and has been reported as Pathogenic/Likely pathogenic by other diagnostic laboratories (ClinVar Variation ID: 2356). -

Pathogenic, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJun 14, 2016The c.2276G>T (p.Cys759Phe) variant is a well described pathogenic variant for USH2A-related disorders. Across a selection of the available literature, the variant is reported in over 90 patients with retinitis pigmentosa and 40 patients with Usher syndrome (Rivolta et al. 2000; Dreyer et al. 2000; Nájera et al. 2002; Rivolta et al. 2002; Bernal et al. 2003; Aller et al. 2004; Seyedahmadi et al. 2004; Bernal et al. 2005; Baux et al. 2007; Dreyer et al. 2008; Sandberg et al. 2008; Ávila-Fernández et al. 2010; Vozzi et al. 2011; Glöckle et al. 2014; Blanco-Kelly et al. 2015; Lenassi et al. 2015). Among those with isolated retinitis pigmentosa, fifteen were found to be homozygous for the variant and 34 were identified as compound heterozygous for the variant. Furthermore, the p.Cys759Phe variant has been found to cosegregate with disease in multiple families (Bernal et al. 2003; Ávila-Fernández et al. 2010). The variant was identified in a heterozygous state in eight of 3400 controls, and is reported at a frequency of 0.00209 in the European American population of the Exome Sequencing Project. The Cys759 residue occurs in a laminin-type epidermal growth factor-like domain. The p.Cys759Phe variant is predicted to disrupt disulfide bond formation and lead to abnormal protein folding (Dreyer et al. 2000; Baux et al. 2007). Based on the collective evidence, the p.Cys759Phe variant is classified as pathogenic for USH2A-related disorders. -
