Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV001778686	SCV002015092	pathogenic	Usher syndrome	2021-10-27	criteria provided, single submitter	clinical testing	Variant summary: USH2A c.9459C>A (p.Cys3153X) 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 was absent in 250418 control chromosomes (gnomAD). c.9459C>A has been reported in the literature in individuals affected with Usher Syndrome and autosomal recessive Retinitis Pigmentosa (e.g. Le Quesne Stabej_2012, Sujirakul_2015). 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. Five ClinVar submitters (evaluation after 2014) cite the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

Labcorp Genetics (formerly Invitae), Labcorp	RCV001388971	SCV001590165	pathogenic	not provided	2023-09-27	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Cys3153*) 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 (rs73090721, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with clinical features of Usher syndrome and/or retinitis pigmentosa (PMID: 22135276, 28559085, 31370859). ClinVar contains an entry for this variant (Variation ID: 48628). For these reasons, this variant has been classified as Pathogenic.

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000041954	SCV000065650	pathogenic	Rare genetic deafness	2012-03-12	criteria provided, single submitter	clinical testing	The Cys3153X variant in USH2A has been reported in one individual with Usher syn drome who was compound heterozygous with a second pathogenic USH2A variant (Le Q uesne Stabej 2012). This nonsense variant leads to a premature termination codon at position 3153, which is predicted to lead to a truncated or absent protein. In summary, this variant meets our criteria to be classified as pathogenic (http ://pcpgm.partners.org/LMM).
