Invitae RCV001229863 SCV001402323 likely pathogenic Arrhythmogenic right ventricular dysplasia 11 2019-07-05 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in DSC2 are known to be pathogenic (PMID: 23911551). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with DSC2-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change affects a donor splice site in intron 1 of the DSC2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product.
