Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000213731 SCV000271475 pathogenic Rare genetic deafness 2015-04-24 criteria provided, single submitter clinical testing The p.Arg2914X variant in USH2A has been previously reported in 4 individuals wi th Usher syndrome (Baux 2014, McGee 2010) and 1 individual with retinitis pigmen tosa (RP) (Zhao 2015), however hearing loss was not evaluated in the latter. At least 4 of these individuals were compound heterozygous for a second pathogenic variant in USH2A. This variant has been identified in 1/66678 European chromoso mes by the Exome Aggregation Consortium (ExAC,, though this frequency is low enough to be consistent with a recessive carrier fr equency. This nonsense variant leads to a premature termination codon at positio n 2914, which is predicted to lead to a truncated or absent protein. Loss of fun ction of the USH2A gene is an established disease mechanism in Usher syndrome. I n summary, the p.Arg2914X variant in USH2A meets our criteria to be classified a s pathogenic for autosomal recessive Usher syndrome based upon the predicted imp act to the protein and the previously reported individuals with Usher syndrome (

Invitae RCV001091129 SCV001399316 pathogenic not provided 2020-08-21 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg2914*) in the USH2A gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs766590491, ExAC 0.001%). This variant has been observed in several individuals with USH2A-related conditions (PMID: 24944099, 25472526). ClinVar contains an entry for this variant (Variation ID: 228417). Loss-of-function variants in USH2A are known to be pathogenic (PMID: 10729113, 10909849, 20507924, 25649381). For these reasons, this variant has been classified as Pathogenic.

Ocular Genomics Institute, Massachusetts Eye and Ear RCV000666615 SCV001573696 likely pathogenic Retinitis pigmentosa 39 2021-04-08 criteria provided, single submitter research The USH2A c.8740C>T variant was identified in an individual with retinitis pigmentosa with a presumed recessive inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PVS1, PM2. Based on this evidence we have classified this variant as Likely Pathogenic.
