Time: 9:00 AM PST / 18:00 CEST
Duration: 1 hour
Speaker: Jennifer Schleit, Christèle du Souich

This is our annual educational webinar on variants of uncertain significance. 

Genetic testing is becoming increasingly widespread in medical practice. Despite increasing use of these technologies, there continue to be variants identified that lack sufficient evidence to determine whether they are related to an individual’s phenotype.  Such variants are classified as variants of uncertain significance (VUS), and receiving this result can be challenging for both clinicians and patients.

During this educational webinar, Laboratory Director Dr Jennifer Schleit and certified genetic counselor Christèle du Souich, will delve into an in-depth discussion on variants of uncertain significance, exploring both the clinical team and diagnostic laboratory’s perspective. We will review the different variant classifications, with specific focus on why certain variants are considered to be of uncertain significance. Possible next steps that could assist with reclassification of variants and familial variant testing in different family structures will be discussed. Finally, we will examine approaches to counselling patients and family members about a VUS.


Webinar objectives:

  • Describe different variant classifications and explain why some variants are considered to be of uncertain significance
  • Examine possible next steps for reclassifying variants of uncertain significance
  • Review different family scenarios and discuss familial variant testing
  • Discuss approaches to genetic counselling about variants of uncertain significance
