HelpTest Code PMARG Postmortem Arrhythmia Gene Panel, Tissue
Ordering Guidance
This test is intended for use when whole blood is not available and formalin-fixed, paraffin-embedded (FFPE) tissue is the only available specimen. If whole blood is available, consider CARGG / Comprehensive Arrhythmia Gene Panel, Varies
Targeted testing for familial variants (also called site-specific or known variants testing) is available for the genes on this panel. See FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.
Specimen Required
Specimen Type: Tissue block
Collection Instructions: Submit a formalin-fixed, paraffin-embedded tissue block
Additional Information: Testing will be attempted on blocks of any age but may be canceled if adequate DNA concentration cannot be obtained.
Forms
1. New York Clients-Informed consent is required. Document on the request form or electronic order that a copy is on file. The following documents are available:
-Informed Consent for Genetic Testing (T576)
-Informed Consent for Genetic Testing (Spanish) (T826)
-Informed Consent for Genetic Testing for Deceased Individuals (T782)
2. Hereditary Cardiomyopathies and Arrhythmias Patient Information (T725)
Useful For
Providing a comprehensive postmortem genetic evaluation in the setting of a sudden death suspicious for cardiac arrhythmia or with a personal or family history suggestive of a hereditary form of cardiac arrhythmia
Identifying a disease-causing variant in the decedent, which may assist with risk assessment and predictive testing of at-risk family members
Genetics Test Information
This test utilizes next-generation sequencing to detect single nucleotide variants and deletions-insertions (delins) in 44 genes associated with hereditary forms of cardiac arrhythmias: ABCC9, ANK2, CACNA1C, CACNA1D, CACNA2D1, CACNB2, CALM1, CALM2, CALM3, CASQ2, CAV3, CDH2, DES, DSC2, DSG2, DSP, EMD, FLNC, GNB5, HCN4, JUP, KCND2, KCND3, KCNE1, KCNE2, KCNH2, KCNJ2, KCNJ8, KCNQ1, LMNA, NKX2-5, PKP2, PLN, PPA2, PRKAG2, RBM20, RYR2, SCN5A, SLC4A3, TECRL, TMEM43, TNNI3K, TRDN, and TTN. See Method Description for additional details.
Identification of a disease-causing variant may assist with familial risk assessment, screening, and genetic counseling for hereditary forms of cardiac arrhythmias.
