Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002471405 SCV002767430 likely pathogenic Catecholaminergic polymorphic ventricular tachycardia 1 2022-02-02 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 (CPVT; MIM#604772) (PMIDs: 12459180, 27646203, 29477366). (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 lysine. (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) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants (Decipher; PMID: 30696458). (SP) 0710 - Other missense variants comparable to the one identified in this case have inconclusive previous evidence for pathogenicity. The p.(Gln3395Glu) variant has been classified once as likely pathogenic, primarily because it has been observed by Invitae in-house as de novo in CPVT individuals while the p.(Gln3395His) variant has been classified as a VUS (ClinVar). (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) (by segregation analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
