A 13-year-old boy with severe muscle cramps was diagnosed with carnitine palmityl transferase deficiency. Dietary changes, including a high-carbohydrate, low-fat diet, successfully managed his symptoms.

Area of Science:

  • Biochemistry
  • Neurology
  • Genetics

Background:

  • Carnitine palmityl transferase (CPT) deficiency is a rare metabolic disorder affecting fatty acid oxidation.
  • It typically presents with exercise-induced muscle pain, weakness, and myoglobinuria.

Observation:

  • A 13-year-old male experienced a decade of severe muscle cramps post-exercise.
  • He had no prior history of exercise intolerance or myoglobinuria.

Findings:

  • Muscle biopsy revealed lipid myopathy and carnitine palmityl transferase deficiency.
  • The patient responded favorably to a high-carbohydrate, low-fat diet, with pre-exercise carbohydrate supplementation.

Implications:

  • Early diagnosis of CPT deficiency is crucial to prevent potential complications like rhabdomyolysis.

  • Dietary management can effectively mitigate symptoms in patients with CPT deficiency.
  • This case highlights the importance of considering metabolic myopathies in young athletes presenting with exertional symptoms.
