Diagnostic Approaches to Rare Genetic Disorders
Inborn errors of metabolism (IEMs) are genetic disorders characterized by a perturbation in a metabolic pathway. Many IEMs can be treated with dietary modifications, pharmacologic supplements, and other therapies. The treatment is more effective when initiated early, before any organ or cell damage has occurred. The prompt diagnosis of IEMs is, therefore, critical to a good outcome. Newborn screening is very successful in identifying infants at birth with known IEMs. Advances in technology and scientific discoveries have broadened the group of rare disorders caused by a metabolic perturbation that can be detected using old and new methodologies. This lecture will focus on new diagnostic approaches for rare disorders and will highlight the importance of integrating clinical, biochemical, and molecular findings.
