Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471814 SCV002766776 likely pathogenic Catecholaminergic polymorphic ventricular tachycardia 1 2022-03-31 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely pathogenic. Following criteria are met: 0103 - Dominant negative and gain of function are known mechanisms of disease in this gene and are associated with catecholaminergic polymorphic ventricular tachycardia 1 (MIM#604772) and left ventricular non-compaction (PMIDs: 12459180, 27646203, 29477366, 31875585, 33500567). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance. Penetrance for CPVT is estimated to be 60-70% (PMID: 23549275). (I) 0200 - Variant is predicted to result in a missense amino acid change from cysteine to arginine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0600 - Variant is located in the annotated Inositol 1,4,5-trisphosphate/ryanodine receptor domain (NCBI). (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. An alternative change to a tryptophan has been reported once as VUS (Global Variome shared LOVD). (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1204 - This variant has been shown to be de novo in the proband (parental status not tested but assumed). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
