Catecholaminergic polymorphic ventricular tachycardia (CPVT) panel
| Genes Sequenced | CORE: 7 genes sequenced: CALM1, CALM2, CALM3, CASQ2, RYR2, TECRL and TRDN. |
| Test Details | DNA extraction, exome capture and sequencing on the Illumina platform. Identified variants are classified using ACMG/AMP and ClinGen guidelines. aCGH send out testing for the RYR2 and TRDN genes is performed when NGS does not identify any pathogenic or likely pathogenic variants. |
| Methodology | Next-generation sequencing |
| Performed | Monday – Friday |
| Turnaround | 3 – 4 weeks |
| Specimen Requirements | Peripheral blood or Buccal swabs |
| Sample Collection | 1 EDTA (lavender top) tube containing 2-5 mL peripheral blood or 2 Buccal swabs |
| Minimum Sample Volume | 1 ml; 1 swab |
| Storage/Transport Conditions | Ambient / room temperature unless delivery will exceed four hours, then refrigerated temperature is preferred. |
| Unacceptable Conditions | Frozen specimens, clotted or hemolyzed specimens, inappropriate tube type |
