Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000041937 SCV000065633 pathogenic Rare genetic deafness 2010-04-02 criteria provided, single submitter clinical testing The Trp2994X variant in USH2A has been reported in 2 probands with Usher syndrom e (Yan 2009). In addition, this variant leads to a premature stop codon at posit ion 2994 and therefore, is predicted to lead to a truncated or absent protein. I n summary, this variant meets our criteria to be classified as pathogenic (http: //

Invitae RCV000760327 SCV001201117 pathogenic not provided 2020-05-27 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Trp2994*) in the USH2A gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in combination with another USH2A variant in individuals affected with Usher syndrome or retinitis pigmentosa (PMID: PMID: 19881469, 28041643). ClinVar contains an entry for this variant (Variation ID: 48611). 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV001193386 SCV001362169 pathogenic Usher syndrome 2019-10-25 criteria provided, single submitter clinical testing Variant summary: USH2A c.8981G>A (p.Trp2994X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 1.6e-05 in 251094 control chromosomes (gnomAD). c.8981G>A has been reported in the literature in individuals affected with Usher syndrome and retinitis pigmentosa (e.g. Carss_2017, Stone_2017, Yan_2009). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submitters (evaluation after 2014) cite the variant twice as pathogenic and once as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
Ocular Genomics Institute, Massachusetts Eye and Ear RCV001376393 SCV001573514 pathogenic Retinitis pigmentosa 39 2021-04-08 criteria provided, single submitter research The USH2A c.8981G>A 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, PP3. Based on this evidence we have classified this variant as Pathogenic.
