Insights
Primary carnitine deficiency can mimic hypertrophic cardiomyopathy, potentially leading to misdiagnosis. Early detection is crucial for effective management and family screening.
Area of Science:
- Cardiology
- Metabolic Disorders
- Genetics
Background:
- Primary carnitine deficiency (PCD) is a rare inherited metabolic disorder affecting fatty acid oxidation.
- PCD can present with cardiac manifestations that overlap with other cardiomyopathies.
- Misattribution to sarcomeric protein dysfunction in hypertrophic cardiomyopathy (HCM) is possible, especially in genotype-negative cases.
Abstract:
Primary carnitine deficiency may mimic hypertrophic cardiomyopathy and be mistakenly attributed to genotype-negative sarcomeric protein dysfunction in hypertrophic cardiomyopathy. Although rare, timely diagnosis may have significant implications on management and should prompt testing of family members.
