Session Description

Recurrent deletions of chromosome sub-band 22q11.2 are estimated to occur as frequently as 1 in 3,000-6,000 live births and 1 in 1,000 unselected fetuses (those without congenital heart disease or palatal anomalies). Chromosome 22q11.2 deletions result in a syndrome that is associated with a broad range of phenotypic features including congenital heart disease, palatal abnormalities, gastrointestinal differences, skeletal anomalies, immune dysfunction, endocrinopathies, cognitive deficits and behavioral problems/psychiatric illness. This webinar will review the clinical presentation of 22q11.2 deletion syndrome in diverse populations. Additionally, it will explore the use of massively parallel sequencing technologies to uncover Mendelian modifiers of this common genomic disorder. 

Learning Objectives

At the conclusion of the series, participants should be able to:

1. Describe the clinical utility of whole exome/whole genome sequencing tests
2. Identify clinical indications for whole exome/whole genome sequencing
3. List determinants used to assess the probability of a variant’s pathogenicity
4. Elaborate on the importance of pre-test counseling and consent

Session Learning Objectives

At the conclusion of this session, participants should be able to:

1. Identify the clinical presentation of 22q11.2 deletion syndrome.
2. Recognize the craniofacial features of 22q11.2 deletion syndrome in diverse populations.
3. Review the clinical utility of massively parallel sequencing to define Mendelian genetic modifiers of classic genomic disorders.
4. Discuss the psychosocial impact of uncovering additional genetic diagnoses on patients and their caregivers.
