Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV003225661 SCV003921904 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 glutamine to proline. (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. In addition, this variant lies within the splice region and while the nucleotide is highly conserved, aberrant splicing is not predicted by in silico tools. (SP) 0603 - Missense variant in a region that is highly intolerant to missense variation (high constraint region in DECIPHER). (SP) 0705 - No comparable missense variants have previous evidence for pathogenicity. (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) 1102 - Strong phenotype match for this individual. (SP) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed; by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
