HELIX DIAGNOSTICS
Dilated Cardiomyopathy Panel
Panel Description
Cardiomyopathies are a broad spectrum of structural and functional disorders of the heart musculature. There are many different causes of cardiomyopathies, which range from environmental exposures to inherited genetic risk factors. In cases where an external cause is not identified, and/or a family history is suspicious for hereditary risk, diagnostic genetic testing may be indicated.
This panel evaluates 66 genes associated with hereditary forms of dilated cardiomyopathy and left ventricular noncompaction cardiomyopathy.

Dilated Cardiomyopathy (DCM) is a condition in which the heart chambers become enlarged, weakening the heart muscle. LVNC is characterized by endomyocardial trabeculations which can have variable effects on heart musculature, including ventricular dilation. Individuals with DCM or LVNC may be asymptomatic, or may be symptomatic with arrhythmia, left ventricular dysfunction, thromboembolic disease, and/or life-threatening arrhythmias.
It is important to note that in some cases DCM and LVNC may be a feature of a larger syndromic condition. Hereditary forms of DCM and LVNC may follow autosomal dominant, autosomal recessive, X-linked or mitochondrial inheritance patterns. This panel does not assess mitochondrial inheritance. Note that some of these genes may also be associated with other unrelated conditions; this means that when undergoing this test, there is a possibility of incidentally detecting carrier status for, or predisposition to, one of these unrelated conditions.
All detected variants are evaluated according to American College of Medical Genetics and Genomics recommendations. Variants are classified based on known, predicted, or possible pathogenicity and reported with interpretive comments detailing their potential or known significance.
