A Case of Mistaken Newborn Screening: Biochemical and Molecular Genetics Join Forces to Make the Right Diagnosis

From the 2020 Joint Annual Meeting (June 30, 2020)
Presented by Linda Hasadsri, MD, PhD
This case highlights two ongoing issues faced by both laboratory geneticists and clinicians involved in the diagnosis of inborn errors of metabolism. Namely, when is there sufficient evidence to classify a VUS as a mutation, and how many patients are potentially missed or misdiagnosed by current methods for newborn screening?

LEARNING OBJECTIVES
At the conclusion of this presentation, participants will be able to:

  1. Summarize the differences between derivatized vs. underivatized tandem mass spectrometry
  2. Identify biochemical laboratory findings in malonic aciduria
  3. Describe methods that can be used to prove the pathogenicity of a newly discovered genetic variant
