Test Code DCM PnlUM DCM/LVNC Sequencing Panel

Important Note

 

This panel has been discontinued by GeneDx Lab and replaced with a 61 gene

DCM/LVNC Sequencing and Deletion/Duplication Panel (Test code J554 at www.genedx.com)

 

This panel includes 38 genes associated with dilated cardiomyopathy.

Clinical System Name

DCM/LVNC Sequencing Panel

Description

Nonsyndromic dilated cardiomyopathy (DCM) is characterized by left ventricular enlargement and systolic dysfunction, a reduction in the myocardial force of contraction. DCM usually presents with any one of the following:

  • Heart failure with symptoms of congestion (edema, orthopnea, paroxysmal dyspnea) and/or reduced cardiac output (fatigue, dyspnea on exertion)
  • Arrhythmias and/or conduction system disease
  • Thromboembolic disease (from left ventricular mural thrombus) including stroke

Sample Requirements

Specimen: Whole Blood

Container(s): Lavender/EDTA

Preferred Vol: 5 mL

Minimum Vol: 2 mL

 

Note: GeneDX does not require consent forms to be completed. Oral rinse (30-40 mL) are also accepted.

Test information sheet

Clinical Utility

This panel can provide confirmation of a clinical diagnosis in symptomatic patients and differentiation of hereditary DCM from acquired (non-genetic) causes of DCM/LVNC. GeneDx estimates that this panel will identify a disease-causing mutation in 40% of patients with familial DCM. If a pathogenic mutation is identified a targeted test can be offered to at-risk family members.
