Time: 9:00 AM PST / 18:00 CET
Duration: 1 hour

Time: 9:00 AM PST / 18:00 CET

The mitochondrial genome is a circular 16.5kb DNA molecule (mtDNA) that encodes 37 genes essential for normal mitochondrial function. Defects in mtDNA result in dysfunction of the mitochondrial respiratory chain, leading to disorders that vary in phenotype, affected tissue(s), and severity. Although mtDNA disorders are relatively common, testing for these disorders can be challenging.

In this webinar, Laboratory Director Dr Jennifer Schleit will review the capabilities of a next-generation sequencing (NGS)-based mtDNA assay that is performed in parallel with nuclear DNA analysis. This technology has allowed for mtDNA analysis to be added to over 30 panels at Blueprint Genetics. We will present our experience including mtDNA analysis as part of clinical genetic testing and demonstrate how this approach increases the diagnostic yield of NGS-based panel testing. Finally, we will present a selection of clinical cases.


Webinar objectives:

  • Review the role of the mitochondrial variants in inherited disease
  • Describe current capabilities in NGS testing for evaluating mtDNA variants at Blueprint Genetics
  • Provide an overview of the recent experiences at Blueprint Genetics adding mtDNA analysis to panel testing
