ClinGen Hearing Loss Variant Curation Expert Panel RCV001004773 SCV001164255 likely pathogenic Usher syndrome 2019-10-23 reviewed by expert panel curation The c.12295-3T>A variant is present in 5/127918 (0.0039%) of European (non-Finnish) chromosomes in gnomAD (PM2). The variant has also been identified in 2 probands with hearing loss, one of whom was diagnosed with Usher syndrome and both probands also harbored the pathogenic p.Glu767Serfs*21 variant in USH2A (PM3, PP4). While this variant does not occur within the canonical splice site (1,2), it has been shown to cause out-of-frame exon skipping in patient-derived cells and pathogenic variants in this exon have been reported in ClinVar (PVS1_Strong, PMID:25649381). In summary, this variant meets criteria to be classified as likely pathogenic for autosomal recessive Usher syndrome based on the ACMG/AMP criteria applied as specified by the ClinGen Hearing Loss Expert Panel (PVS1_Strong, PM3, PM2, PP4).

GeneDx RCV000414389 SCV000490875 pathogenic not provided 2016-08-15 criteria provided, single submitter clinical testing The c.12295-3T>A variant in the USH2A gene has been reported previously in individuals with Usher syndrome type II and non-syndromic autosomal recessive retinitis pigmentosa (arRP) (Le Quesne Stabej et al., 2012; Lee et al., 2015; Lenassi et al., 2015). RNA functional studies of the c.12295-3T>A variant indicate that it is associated with an out-of-frame skipping of exon 63, which leads to the expression of a smaller transcript and results in a premature termination codon (Lenassi et al., 2015). The c.12295-3T>A variant was not observed at any significant frequency in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret c.12295-3T>A as a pathogenic variant.
Invitae RCV000414389 SCV001207341 pathogenic not provided 2019-12-01 criteria provided, single submitter clinical testing This sequence change falls in intron 62 of the USH2A gene. It does not directly change the encoded amino acid sequence of the USH2A protein, but it affects a nucleotide within the consensus splice site of the intron. This variant is present in population databases (rs111033518, ExAC 0.002%). This variant has been observed in individual(s) with clinical features of USH2A-related disease (PMID: 25649381, 25910913, 22135276). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 48395). Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Experimental studies have shown that this variant disrupts mRNA splicing (PMID: 25649381). For these reasons, this variant has been classified as Pathogenic.
