Session Description
This session highlights the 2019 advances made in the genetic etiology of holoprosencephaly using exome sequencing. We begin with a brief review of the clinical aspects of holoprosencephaly and then work through a case study where exome sequencing resulted in a genetic etiology in a gene not previously associated with human disease. Next, we describe the results for exome sequencing for a cohort of 322 individuals affected with holoprosencephaly and the translational value of these results. Finally, we make a case for applying genome sequencing to our cohort, which is currently underway.
Learning Objectives
At the conclusion of the series, participants should be able to:
- Describe the clinical utility of whole exome/whole genome sequencing tests
- Identify clinical indications for whole exome/whole genome sequencing
- List determinants used to assess the probability of a variant’s pathogenicity
- Elaborate on the importance of pre-test counseling and consent
Session Learning Objectives
At the conclusion of this session, participants should be able to:
- Describe the clinical characteristics of holoprosencephaly.
- Identify the four most common genes associated with holoprosencephaly
- Explain the challenges assigning pathogenicity to variants in new genes associated with holoprosencephaly.
- Identify the inheritance patterns of holoprosencephaly discussed in this session.
