Cardiovascular Diseases Genetic Testing Program Description: Congenital Heart Disease Panels We offer comprehensive gene panels designed to • Congenital Heart Disease Panel (187 genes) diagnose the most common genetic causes of hereditary • Heterotaxy Panel (114 genes) cardiovascular diseases. Testing is available for congenital • RASopathy/Noonan Spectrum Disorders Panel heart malformation, cardiomyopathy, arrythmia, thoracic (31 genes) aortic aneurysm, pulmonary arterial hypertension, Marfan Other Panels syndrome, and RASopathy/Noonan spectrum disorders. • Pulmonary Arterial Hypertension (PAH) Panel Hereditary cardiovascular disease is caused by variants in (20 genes) many different genes, and may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. Other Indications: than condition-specific panels, we also offer single gene Panels: sequencing for any gene on the panels, targeted variant • Confirmation of genetic diagnosis in a patient with analysis, and targeted deletion/duplication analysis. a clinical diagnosis of cardiovascular disease Tests Offered: • Carrier or pre-symptomatic diagnosis identification Arrythmia Panels in individuals with a family history of cardiovascular • Comprehensive Arrhythmia Panel (81 genes) disease of unknown genetic basis • Atrial Fibrillation (A Fib) Panel (28 genes) Gene Specific Sequencing: • Atrioventricular Block (AV Block) Panel (7 genes) • Confirmation of genetic diagnosis in a patient with • Brugada Syndrome Panel (21 genes) cardiovascular disease and in whom a specific gene • Catecholaminergic Polymorphic Ventricular Tachycardia associated diagnosis is suspected (CPVT) Panel (11 genes) Variant Specific Analysis: • Long QT Syndrome Panel (19 genes) • Pre-symptomatic testing of at-risk siblings and parents for medical management • Short QT Syndrome Panel (6 genes) • Carrier identification in individuals in whom specific Connective Tissue Disorders Panel variant(s) have been identified in the proband • Thoracic Aortic Aneurysm Panel (49 genes) • Prenatal diagnosis of an at-risk fetus, after • Marfan Syndrome and MFS Related Disorders Panel confirmation of variant(s) in the parent(s) and by (3 genes) prior arrangement only Cardiomyopathy Panels Deletion/Duplication Analysis: • Comprehensive Cardiomyopathy Panel (135 genes) • Completion of the diagnostic evaluation in a patient • Arrhythmogenic Right Ventricular Cardiomyopathy with a clinical diagnosis of cardiovascular disease (ARVC) Panel (18 genes) who has had a negative panel or who is heterozygous • Dilated Cardiomyopathy (DCM) Panel (73 genes) for a variant in a gene associated with an autosomal • Hypertrophic Cardiomyopathy (HCM) Panel (98 genes) recessive condition. • Left Ventricular Noncompaction (LVNC) Panel (36 genes) • Restrictive Cardiomyopathy (RCM) Panel (9 genes) Laboratory of Genetics and Genomics CLIA#: 36D0656333 Phone: (513) 636-4474 Fax: (513) 636-4373 Email: [email protected] www.cincinnatichildrens.org/genetics Specimen: Test Sensitivity: Provide at least 3 mL of whole blood in a lavender top Analytical Sensitivity: The sensitivity of DNA sequencing (EDTA) tube or saliva in an Oragene saliva kit.

Only single base pair changes or small Panels: Our panels utilize Exome Sequencing (ES) insertions or deletions of DNA are detected. Large technology to detect variants in predefined lists of deletions, duplications, or rearrangements, clinically relevant genes to identify inherited forms of mitochondrial genome mutations, repeat expansions, cardiovascular diseases.
