Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002470284 SCV002767023 uncertain significance Catecholaminergic polymorphic ventricular tachycardia 1 2022-09-02 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. 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). Loss of function has been reported for ventricular arrhythmias due to cardiac ryanodine receptor calcium release deficiency syndrome (MIM#115000), however dominant negative mechanism has not been excluded (PMID: 33536282). (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 histidine to asparagine. (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 (PMID: 30696458). (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) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
