Test Code DCLNG Dilated Cardiomyopathy and Left Ventricular Noncompaction Cardiomyopathy Gene Panel, Varies


Ordering Guidance


This test is intended for genetic screening for and diagnosis of dilated cardiomyopathy or left ventricular noncompaction.

 

For comprehensive cardiomyopathy genetic testing, order CCMGG / Comprehensive Cardiomyopathy Gene Panel, Varies.

 

Customization of this panel and single gene analysis for any gene present on this panel are available. For more information see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.

 

Targeted testing for familial variants (also called site-specific or known mutations 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.

Genetics Test Information

This test utilizes next-generation sequencing to detect single nucleotide and copy number variants in 63 genes associated with hereditary forms of dilated cardiomyopathy and left ventricular noncompaction: ABCC9, ACAD9, ACADVL, ACTC1, ACTN2, ALMS1, ALPK3, BAG3, CDH2, CPT2, CRYAB, CSRP3, DES, DMD, DNAJC19, DOLK, DSC2, DSG2, DSP, EMD, FKRP, FKTN, FLNC, GAA, GLA, HCN4, JPH2, JUP, LAMP2, LMNA, MYBPC3, MYH7, MYLK3, MYPN, NEXN, NKX2-5, PCCA, PCCB, PKP2, PLN, PPA2, PPCS, PRDM16, RAF1, RBM20, RYR2, SCN5A, SGCD, SHOC2, SLC22A5, TAZ (TAFAZZIN), TBX20, TCAP, TMEM43, TMEM70, TNNC1, TNNI3, TNNI3K, TNNT2, TPM1, TTN, TTR, and VCL. See Targeted Genes and Methodology Details for Dilated Cardiomyopathy and Left Ventricular Noncompaction Cardiomyopathy 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 dilated cardiomyopathy and left ventricular noncompaction.
