Inherited Cardiovascular Disease

Innovative Gx Health (IGx) is a CAP-accredited, CLIA-certified laboratory offering next-generation sequencing to diagnose inherited cardiovascular diseases. IGx’s panels analyze both sequencing variants and copy number variants in genes associated with inherited cardiovascular diseases. Genetic testing for inherited cardiovascular diseases offers the following benefits: provides actionable information for the clinical management of various inherited cardiovascular diseases such as cardiomyopathies, arrhythmic disorders, thoracic aortic aneurysms, and familial hypercholesterolemia (FH), facilitates early intervention, informs family planning, and promote enrollment in research studies

People with an inherited cardiovascular disease have a higher risk for developing certain structural or functional issues in the heart due to a genetic variant that is passed down in their family. Most people are unaware they have an inherited cardiovascular disease because they often show no signs or symptoms, beyond a personal or family history of cardiovascular disease. Cardiovascular diseases are usually diagnosed via routine lab tests, such as electrocardiogram (EKG) and echocardiogram, while genetic testing is the only option available for diagnosing inherited forms of cardiovascular diseases.

Test Specifics

Innovative Gx Laboratories (IGx) is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory offering next-generation sequencing of coding regions and splice site junctions to detect both sequencing variants and copy number variants. Single-exon deletions or duplications, repeat expansions and deep intronic regions (greater than 20bp from an exon) may not be detected by this test. This test is not designed or validated for the detection of somatic mosaicism. Sanger sequencing is used to confirm variants with low quality scores and to meet coverage standards. Identified putative deletions or duplications are confirmed by an orthogonal method (qPCR or MLPA). Due to high GC content of certain exons, copy number analysis may have reduced sensitivity for partial gene deletions/duplications of TRDN. Confirmation of partial gene deletions/duplications are limited to individuals with a positive personal history of cardiac arrhythmia and/or individuals carrying a pathogenic/likely pathogenic sequence variant.
