OVERVIEW

WHAT IS VENTRILIA?

Ventrilia is a genetic test that analyzes up to 292 genes to detect mutations that can cause multiple cardiovascular conditions with complex phenotypes. It can be used to identify genetic mutations associated with cardiovascular diseases in:
symptomatic individuals with a clinically diagnosed cardiovascular condition
presymptomatic individuals with a clinically diagnosed cardiovascular condition
asymptomatic individuals that belong in high-risk groups

Cardiovascular diseases are the leading cause of illness and death worldwide, responsible for 31% of all global deaths*. Previously, assessment of the disease risk was based on the lifestyle of an individual. The role of genetic testing is now becoming increasingly important, as overlapping symptoms make it very challenging to clearly identify the underlying cardiovascular condition. Genetic testing can detect the underlying condition, provide a prognosis and identify at-risk family members, who might be predisposed to the same cardiovascular disease. Identification of a genetic mutation that causes a disease, can lead to an improved prognosis as well as effective clinical management and treatment for many cardiovascular conditions†.

WHY GET TESTED?

Ventrilia can help for:
Faster identification of complex cardiovascular conditions
Accurate detection of multiple cardiovascular genetic mutations
Early identification in asymptomatic patients
Improved prognostic assessment

OUR TESTS

Ventrilia tests detect clinically actionable genetic alterations, including Single Nucleotide Variants (SNVs), Insertions and Deletions (INDELs), Copy Number Amplifications (CNAs), and Rearrangements, that are associated with cardiovascular diseases.

ACCEPTED MATERIAL

TURNAROUND TIME

2-4 weeks from sample receipt in our laboratory

TECHNOLOGY

gDNA is extracted using a standardized methodology and subjected to mechanical fragmentation prior to DNA library preparation. DNA enrichment for the genomic regions of interest is carried out using a solution-based hybridization method, followed by next generation sequencing (NGS). Single nucleotide variants, small insertions and deletions (≤30bp), and copy number variations (CNVs) are reported. All positive CNVs are confirmed using an orthogonal method. The test aims to detect all coding exons, of MANE and/or Canonical transcripts, and 10bp of adjacent intronic sequence.
Exceptions may include: regions containing repeats, sequences of high homology such as segmental duplications and pseudogenes, as well as regions of extreme GC-content.

Variants are classified according to the criteria set by the American College of Medical Genetics and Genomics. Classification and interpretation of variants is performed using the Varsome Clinical platform, and is according to the published knowledge at the time of testing.
