Conquer the genetic complexity of inherited cardiac arrhythmias with database and software solutions for analyzing and interpreting large NGS multigene panels
Individuals carrying a pathogenic variant for a dominantly inherited arrhythmia have a 50% likelihood of passing the variant on to their children, placing them at higher risk of developing the potentially life-threatening condition (1).
Today, there are a several commercially available sequencing options for genetic testing of inherited arrhythmias, ranging from targeted panels (5-20 genes) to broad pan-arrhythmia panels (170+ genes) and whole exome sequencing (20,000+ genes). While more comprehensive tests increase the sensitivity of variant detection, they also increase the detection of variants of unknown clinical significance, enhancing the complexity of interpretation.
There are several types of inherited arrhythmic disorders. The most common types include:
The greatest challenge with any genetic testing is interpretation of results. However, as NGS panels for inherited arrhythmic disorders continue to increase in size, data analysis and interpretation becomes more complex and time-consuming.
Genetic heterogeneity – most inherited arrhythmia disorders are characterized by mutations in multiple genes.
Variants of unknown significance (VUS) – multigene panel testing increases the number of detected VUS, often in genes with limited evidence.
Specialized knowledge – interpreting genetic results requires a high degree of specialized knowledge.
Future reclassifications – many VUS will likely require future reclassification as additional evidence about the variant becomes available.
