Cardiac and Aortic Panels Know&Manage

OVERVIEW

KNOW

Hereditary cardiac disorders have a prevalence of 3% in the population. Arrythmogenic diseases are responsible for most cardiac mortality in the young, and congenital heart defects are the most common type of birth defect (1% of all live births). Owing to improved treatment and management options, there are more adults living with congenital heart defects than children. Importantly, deaths from aortic aneurysms may be prevented if individuals at risk are identified and managed. Many cardiac and aortic disorders show overlapping cardiac and non-cardiac symptoms, and genetic testing can help with a differential diagnosis in those cases. nWe offer comprehensive and syndrome-specific panels testing for cardiac and aortic disorders.

MANAGE

Genetic information can improve clinical management by determining the right treatment and follow-up plan. It can predict a prognosis and therapy response and, in some cases, identify gene therapy options. nnKnowing about a cardiac or aortic disorder allows you to be proactive about your health with management strategies, such as medication, lifestyle changes or surgery.n

ACCEPTED MATERIAL

1 ml EDTA Blood
Please note: DO NOT FREEZE. Ship with a frozen ice pack. Prepare the package such that the tube is tightly packed and not loose. Avoid getting the blood tube wet from the ice pack. Place a paper towel in between ice pack and blood tube if necessary. In sub-zero temperatures, include an unfrozen ice pack in the shipping container as insulation.

TURNAROUND TIME

15-25 working days

TECHNOLOGY

DNA is isolated and next generation sequencing is performed on all coding exons and conserved intronic regions. Single base pair changes, small deletions and duplications and copy number variants (CNV) are identified. Sequencing runs result in a Quality Score of u0026gt;30 (accuracy u0026gt;99.9%) in at least 75% of all bases with a coverage of u0026gt;20-fold. CNV detection sensitivity is 76.99% and precision is 62.59% (with GC limitation between 0.4 and 0.6 per target sensitivity is 77.04% and precision is 84.10%). Variant classification is performed following ACMG guidelines (Richards et al. 2015, Genet Med 17:405; Kearney et al. 2011, Genet Med 13:680).

POSSIBLE OUTCOMES OF THE TEST

A molecular genetic diagnostic report outlining the results of the sequencing analysis is provided. Changes in DNA sequences (variants) can be detrimental and lead to the development of a cardiac or aortic disorder, including asymptomatic disorders that develop later in life. We will report pathogenic and likely pathogenic variants as well as variants of unknown significance.nPathogenic and likely pathogenic variants mean the genetic cause of the observed symptoms has been identified and may help determine the right treatment and management plan. nVariants of unknown significance means there was not enough evidence to classify the variant as either pathogenic or neutral. Annual variant reclassification and testing family members is recommended.nIt is important to note that a negative result does not guarantee the absence of a disorder or that the disorder does not have a genetic cause. Genetic testing is an evolving field and may not detect all variants or there may not currently be enough evidence to classify all variants that lead to an inherited disease.n

MEDICAL GENETIC COUNSELLING

We provide expert medical genetic counselling as part of a genetic testing journey. Genetic counselling is a process of communication that supports patients and their relatives before and after genetic testing. It is educational, impartial and nondirective. Prior to any genetic test, genetic counsellors will obtain a detailed family history, explain the method of testing that will be used, its risks and benefits, the limitations of the diagnosis and the implications of making a genetic diagnosis (Elliott and Friedman, 2018, Nat Rev Genet 19:735).nnUpon receiving the genetic test results, genetic counselling can help the specialist physician and the patient to interpret them. They can be advised of the consequences of the results including the probability of developing the genetic disorder or passing it on to children, as well as ways to prevent, avoid or reduce these risks (Yang and Kim, 2018, Ann Lab Med 38:291). Our goal of counselling is to provide the patient with greater knowledge and thus, a better understanding of the results and the ability to make a more informed decision.
