How a Biochemical Genetics Laboratory Confirmation Testing Interfaces with Positive Newborn Screening Tests: Case Focus on Homocystinuria and Duchenne Muscular Dystrophy
An educational offering sponsored by the American College of Medical Genetics and Genomics (ACMG) with contributions from the Association for Diagnostics & Laboratory Medicine (ADLM)
Description
A case-based webinar to highlight the importance of biochemical genetics laboratory testing in the diagnosis of pediatric patients who are positive by a state newborn screening assay. This webinar will focus on the often diagnostic odyssey associated with a newborn diagnosis Homocystinuria and Duchenne Muscular Dystrophy and how to parse out the false positives from the true positives. Each speaker will provide case examples of diagnostic odyssey in each disease state where the newborn screen results or confirmatory results were unclear and additional confirmation testing was required (i.e. additional biochemical genetics testing following an algorithm or molecular testing).
Target Audience
Medical and clinical geneticists; maternal-fetal specialists; and all medical practitioners who are providing comprehensive diagnostic, management, and counseling services for patients with, or at risk for, genetically influenced health problems.
Learning Objectives
At the conclusion of this session, participants should be able to:
- Describe challenges faced when novel newborn screening programs are put into place
- Discuss results from biochemical genetics assays for Homocystinuria and Duchenne Muscular Dystrophy
- Describe additional data required to continue to improve newborn screening programs (i.e. premie reference ranges)
