GeneDx now offers genetic testing services for Hypertrophic Cardiomyopathy, Dilated Cardiomyopathy, Long QT Syndrome, Brugada Syndrome, Arrhythmogenic Right Ventricular Cardiomyopathy and Catecholaminergic Polymorphic Ventricular Tachycardia. GeneDx aims to offer clinically relevant and comprehensive test panels, which are carefully researched, based on peer-reviewed research publications, and are reviewed by thought leaders in the cardiology and genetics communities. Our advanced technologies paired with patient-friendly billing services allow us to keep the cost of each test as low as possible. GeneDx accepts any commercial insurance in the US for cardiology genetic testing services, and works with insurance companies to make sure that the out of pocket cost for the patient is minimized as much as possible. While being cost-effective, our tests use highly sensitive technology and results are analyzed by board-certified cardiologists and geneticists.

A:Once a specimen is received at GeneDx, it goes through the following steps:
- Next Generation Sequencing: Multiple genes offered in a test panel are analyzed simultaneously using a new technology developed for high-throughput sequencing (“next generation sequencing”) to achieve high sensitivity with high efficiency. This method is also flexible and permits adding new genes to the existing panel without delay or significant cost increase.
- Confirmation of Results by Dideoxy Sequencing: All mutations identified by next generation sequencing are confirmed by traditional dideoxy sequencing, or another appropriate method.
- Additional Studies to Evaluate Variants of Unknown Significance (VOUS): When indicated, the presence or absence of novel sequence variants in representative, ethnically-matched control populations is evaluated using either publicly available resources or targeted laboratory studies.
- Result Interpretation and Reporting: Results are analyzed and interpreted at minimum by a geneticist and a genetic counselor, and are then reported to the ordering physician.
- Experts Are Only a Phone Call or Email Away: At GeneDx, our technical services are matched by our expertise and customer support. Our growing staff includes more than 30 experts in molecular and clinical genetics, cardiology and genetic counseling, who are just a phone call or email away. Our team works together on each individual case to provide unequivocal test sensitivity, efficiency and expertise. Genetic counselors are available to answer your questions and help manage patient cases through the testing experience.
A:Identification of a disease-causing mutation in an affected individual allows for mutation-specific genetic testing of at-risk family members. This includes family members who are clinically asymptomatic and who may have normal cardiac evaluations. Knowing whether at-risk family members harbor the disease-causing mutation can provide information for subsequent medical management and treatment, risk-assessments and prenatal diagnosis in future pregnancies if desired.

A:There are several reasons an individual or family may be referred for genetic testing in cardiac disorders. Genetic testing in a clinically affected patient can clarify the diagnosis, assist in treatment decisions and stratify risk management of family members. Diagnostic genetic testing can also help in differential diagnosis. For example, genetic testing in patients with symptoms of HCM can differentiate hereditary HCM from heart disease due to other causes, such as “Athlete’s Heart” and from HCM associated with mutations in sarcomeric genes from phenocopies, such as Fabry disease and Amyloidosis. Mutation-specific testing assists in risk assessment of asymptomatic family members, and if desired, prenatal testing is available.
