CardioGene is comprised of 4 different NGS panels to ensure detailed coverage of the genes responsible for causing Inherited Cardiac Conditions (ICCs). It is performed on a blood sample, ideally on someone who is affected with an ICC.
Depending on the particular type of ICC found in the patient or their family, the following genes may be tested: HCM, ARVC/DCM, IAS, ICD/SD. The appropriate NGS panel will be discussed prior to testing.
There are 3 possible outcomes:
If a mutation is not identified, this does not mean that your ICC is not genetic, just that we have been unable to currently determine a genetic cause. Future genetic testing may be available depending on your condition. What does it mean if I have a mutation? If the test identifies a mutation in your saliva sample, this means we have identified the cause of your/ your family’s ICC and that unaffected family members may benefit from a genetic test. It is unlikely that your clinical management will change upon the identification of a specific faulty gene; however for a few genes this may be the case.
Presently, it is not possible to predict the clinical course of your ICC based on a particular gene or mutation as there generally is not a consistent correlation between the two. The specific gene identified will inform us how your ICC is inherited and will help us in determining which of your family members require clinical screening and who would benefit from genetic testing.
As the detection rate is less than 100%*, testing is usually only performed on individuals who are affected with the condition. This is because the absence of a mutation in someone who is not affected would not be informative.
The test is performed on a blood sample and takes x days to obtain a result. Gene coverage is almost 100% for the most common genes for each ICC. This figure does vary between patients and is also affected by sample processing.
*current detection rates vary depending on the ICC
When an ICC has been identified in the family, it is advisable that all first degree family members undergo clinical screening by a cardiologist. This is regardless of whether a genetic mutation can be identified in the family and should also taken place even in the absence of symptoms. The intervals and timings of screening should be discussed with your cardiologist and will be dependent on age and type of ICC.
Inherited Cardiac Conditions (ICC)
Inherited Cardiac Conditions, or ICC, are a group of heart conditions that are due to a genetic cause. The most common types of inherited cardiac conditions are the cardiomyopathies and the inherited arrhythmia syndromes (IAS).
Genes come in pairs; one copy is inherited from our mother and one copy from our father. The majority of ICCs are inherited in an autosomal dominant (AD) manner, which means that there is a 1 in 2, or 50% chance, that an affected parent will pass the faulty gene onto each of their children. However, there are some rarer types of heart conditions that are inherited in an X-linked pattern, where boys are more commonly affected than girls (see diagram).
At GeneHealth UK we offer genetic counselling to assist you prior to genetic testing. Our counsellors will provide you with all the information you need to make a decision and will help explain the process of genetic testing to you. Our counsellors will also be available after your test to discuss the results and your options.
The price list for CardioGene is available here. All services include pre and post-test genetic counselling.
If you would like further information and advice on genetic testing for cardiovascular disease please contact our team today.
