Useful For

Providing a genetic evaluation for patients with a personal or family history suggestive of a hereditary form of cardiac arrhythmia

 

Establishing a diagnosis of a hereditary form of cardiac arrhythmia

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants 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 Targeted Genes and Methodology Details for Comprehensive Arrhythmia Gene Panel and Method Description for additional details.

 

Identification of a disease-causing variant may assist with diagnosis, prognosis, clinical management, familial screening, and genetic counseling for hereditary forms of cardiac arrhythmias.
