RCV003038682 | SCV003326962 | pathogenic | not provided | 2022-11-14 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with USH2A-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp4464*) 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). |

RCV004594662 | SCV005086444 | pathogenic | Usher syndrome type 2A | 2023-07-17 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Usher syndrome type 2A (MIM#276901) and retinitis pigmentosa 39 (MIM#613809). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0701 - Other variants causing NMD comparable to the one identified in this case have very strong previous evidence for pathogenicity (DECIPHER). (SP) 0803 - This variant has limited previous evidence of pathogenicity in unrelated individuals. This variant and a substitution of an adjacent nucleotide (c.13392G>A) resulting in the same protein change have been reported as pathogenic in ClinVar by a diagnostic laboratory. (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
