Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)
Introduction
We simultaneously sequence 5 genes known to cause catecholaminergic polymorphic ventricular tachycardia (CPVT). We provide a comprehensive scientific interpretation of variants found and issue a report summarising our findings.
Referral information
For individuals with clinical features consistent with catecholaminergic polymorphic ventricular tachycardia (CPVT) – (ECG normal, exercise ECG with bidirectional ventricular tachycardia reproducibly elicited during adrenergic stimulation). On identification of a pathogenic change in an index case presymptomatic testing of relatives can be offered. Referrals for testing are only accepted from a Consultant Cardiologist or a Consultant Clinical Geneticist (please contact the Clinical Genetics department for specific information). Referrals should be accompanied by a clinical diagnosis and details of family history. Referrals should also be accompanied by a completed standard referral form available in the Referral Forms section. For optimal results please send a fresh EDTA blood sample (1-4ml) or a minimum of 5µg of extracted DNA. For a full list of genes included in the assay please contact the laboratory.
Technical information
Genes are tested by next generation sequencing (more information is available on request). We undertake a complete scientific analysis to highlight variants with a high likelihood of pathogenicity which are subsequently confirmed using conventional Sanger sequencing. On completion of the analysis a report is issued incorporating a clinical interpretation of all pathogenic mutations identified. In addition a technical report is made available to referrers summarising the coverage of the analysis and incorporating a full list of (non-validated) variants.
