Invitae RCV003638740 SCV004549834 pathogenic Catecholaminergic polymorphic ventricular tachycardia 1 2023-11-08 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 1 of the TRDN gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in TRDN are known to be pathogenic (PMID: 22422768, 25922419, 26200674, 30649896). This variant is present in population databases (no rsID available, gnomAD 0.0009%). Disruption of this splice site has been observed in individuals with clinical features of triadin knockout syndrome (PMID: 34415104; Invitae). ClinVar contains an entry for this variant (Variation ID: 915308). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
