RCV001004618 | SCV000927012 | likely pathogenic | Usher syndrome | 2022-11-22 | reviewed by expert panel | curation | The p.Ile1183fs variant in USH2A introduces a premature stop codon in biologically-relevant-exon 17/72 that is predicted to lead to a truncated or absent protein in a gene in which loss-of-function is an established disease mechanism (PVS1; PMIDs: 9624053, 25211151, 20497194). The highest population minor allele frequency in gnomAD v2.1.1 is 0.00088% (1/113352 alleles) in the European (non-Finnish) population, which is lower than the ClinGen Hearing Loss VCEP threshold (<0.007%) for PM2_Supporting, meeting this criterion (PM2_Supporting). One proband with autosomal recessive retinitis pigmentosa was identified to be carrying the p.Ile1183fs variant with no variant reported in trans (PMID: 35266249). This variant was re-reviewed on 11/22/2022 and because no additional evidence is available, professional judgment was used to retain this variant as likely pathogenic for autosomal recessive Usher Syndrome based on the ACMG/AMP criteria applied as specified by the ClinGen Hearing Loss VCEP: PVS1, PM2_P (ClinGen Hearing Loss VCEP specifications version 2; 11/22/2022). |

RCV000824789 | SCV000065525 | pathogenic | Rare genetic deafness | 2011-03-31 | criteria provided, single submitter | clinical testing | The Ile1183fs variant in USH2A has not been reported in the literature nor previ ously identified by our laboratory. The Ile1183fs variant is predicted to cause a frameshift, which alters the protein's amino acid sequence beginning at codon 1183 and leads to a premature stop codon 18 codons downstream. This alteration i s then predicted to lead to a truncated or absent protein. In summary, this vari ant meets our criteria to be classified as pathogenic. |

RCV001388470 | SCV001589469 | pathogenic | not provided | 2023-10-17 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Ile1183Phefs*19) in the USH2A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in USH2A are known to be pathogenic (PMID: 10729113, 10909849, 20507924, 25649381). This variant is present in population databases (rs397518013, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 48503). For these reasons, this variant has been classified as Pathogenic. |
