RCV002515600 | SCV000760640 | pathogenic | Catecholaminergic polymorphic ventricular tachycardia 1 | 2020-12-09 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in TRDN are known to be pathogenic (PMID: 25922419). This variant has not been reported in the literature in individuals with TRDN-related disease. ClinVar contains an entry for this variant (Variation ID: 225497). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Ile190Asnfs*2) in the TRDN gene. It is expected to result in an absent or disrupted protein product. |

The rationale for this assessment is: type of variant in this gene likely to be pathogenic, sufficiently rare. Gene-level evidence TRDN variants are newly recognized as a cause of autosomal recessive arrhythmic syndromes resembling CPVT and long QT syndrome. Several of the reported pathogenic variants are nonsense, frameshift, or splice. As far as we are aware phenotype in heterozygotes has not been reported. Case data summary Per lab report and my searches, variant has not been reported with disease. Population Data There is no variation at this genomic position in gnomAD. Metrics indicate adequate coverage. |
