Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 29, 2024 | This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1369 of the USH2A protein (p.Ser1369Leu). This variant is present in population databases (rs201709513, gnomAD 0.08%). This missense change has been observed in individual(s) with USH2A-related disease (PMID: 20591486, 24154662, 26927203, 27957503, 31047384; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 48511). 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 not expected to disrupt USH2A protein function with a negative predictive value of 95%. 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. - |

Usher syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Oct 31, 2024 | Variant summary: USH2A c.4106C>T (p.Ser1369Leu) 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 benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00016 in 250578 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in USH2A causing Usher Syndrome (0.00016 vs 0.011), allowing no conclusion about variant significance. c.4106C>T has been reported in the literature in multiple individuals affected with Usher Syndrome and/or with Retinitis Pigmentosa (e.g. Zhao_2015, Dad_2016, Santos_2022, Lynn_2022). Furthermore, the variant was shown to co-segregate with retinitis pigmentosa in siblings from two different families (Wang_2014, Comander_2017). At-least one putative "in cis" co-occurrence of the variant with either of two other pathogenic variants (c.9270C>A, p.C3090X or c.6159delA, p.E2054KfsX10; phase unknown) has been reported in one RP patient (Wang_2014), while in another instance following internal testing the variant was reported in cis (confirmed via parental studies) with a pathogenic variant (c.6159delA, p.E2054KfsX10) in one individual.Nevertheless, these data indicate that the variant is very likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 30245029, 26075083, 28981474, 16963483, 27957503, 31429209, 26927203, 24154662, 25097241, 25472526, 36003347, 36672815). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. ClinVar contains an entry for this variant (Variation ID: 48511). Based on the evidence outlined above, the variant was classified as pathogenic. - |

USH2A-related disorder Pathogenic:1
Likely pathogenic, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Mar 22, 2024 | The USH2A c.4106C>T variant is predicted to result in the amino acid substitution p.Ser1369Leu. This variant has been reported in multiple unrelated patients with Usher syndrome or retinitis pigmentosa (Table S4, Pierrache et al. 2016. PubMed ID: 26927203; Dad et al. 2015. PubMed ID: 25804404; Comander et al. 2017. PubMed ID: 28981474; Wang et al. 2014. PubMed ID: 24154662; Colombo et al. 2015. PubMed ID: 26075083; Table S2, Zampaglione et al 2020. PubMed ID: 32037395; Molina-Ramírez et al 2020. PubMed ID: 32176120; Tables S5 and S7, Colombo et al 2021. PubMed ID: 33576794). This variant has been reported in conjunction with a pathogenic USH2A variant in multiple individuals, however, segregation analysis to determine phase was not reported for all cases (Hariri et al. 2017. PubMed ID: 31047384; Yohe et al 2019. PubMed ID: 31816670; Molina-Ramírez et al. 2020. PubMed ID: 32176120; Colombo et al. 2021. PubMed ID: 33576794; Lynn et al. 2022. PubMed ID: 36672815; Panneman et al. 2023. PubMed ID: 36819107). This variant was also shown to segregate with disease in siblings from two unrelated families with retinitis pigmentosa (Wang et al. 2013. PubMed ID: 24154662; Comander et al. 2017. PubMed ID: 28981474). This variant is reported in 0.077% of alleles in individuals of Ashkenazi Jewish descent in gnomAD and has conflicting interpretations in ClinVar ranging from uncertain to pathogenic (https://www.ncbi.nlm.nih.gov/clinvar/variation/48511/). This variant is interpreted as likely pathogenic. - |
Retinitis pigmentosa Pathogenic:1
Likely pathogenic, criteria provided, single submitter | curation | Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard | Apr 01, 2021 | The p.Ser1369Leu variant in USH2A was identified in an individual with Retinitis pigmentosa, via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Pierce lab (https://oculargenomics.meei.harvard.edu/labs/pierce-lab/lab-members/). Through a review of available evidence we were able to apply the following criteria: PS1, PM2, PP1, PP3. Based on this evidence we have classified this variant as Likely Pathogenic. If you have any questions about the classification please reach out to the Pierce Lab. - |
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Oct 25, 2016 | The p.Ser1369Leu variant in USH2A has been previously reported in three individu als with Usher syndrome, one individual with retinitis pigmentosa, and one indiv idual with hearing loss (Colombo 2015, Cremers 2007, Dad 2015, Wang 2014, LMM da ta). In the proband with retinitis pigmentosa, a second variant of uncertain si gnificance was identified and the two variants segregated in an affected sibling ; however, cis/trans testing was not performed (Wang 2014). In the remaining pr obands, a pathogenic variant affecting the remaining copy of USH2A was not ident ified. This variant has been identified in 13/65610 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs201 709513); however, this frequency is not high enough to rule out a pathogenic rol e. The serine (Ser) at position 1369 is not conserved through species, with 2 m ammals (squirrel and brush-tailed rat) and 2 bird species having a leucine, sugg esting that this change may be tolerated. Additional computational prediction t ools do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Ser1369Leu variant is uncertain. - |
