Quick Summary

Carnitine is a compound essential for transferring fatty acids into mitochondria for energy production. Pathology arises when there are deficiencies in carnitine transport or related enzymes, such as acylcarnitine transferase. This disruption leads to lipid storage myopathies, where fat accumulates within muscle fibers, impairing muscle function.

Defects in carnitine transport can cause severe damage to the brain, liver, and heart. These conditions are often inherited and can manifest with symptoms like hypoglycemia, liver disease, decreased muscle tone, and heart failure. While treatment with carnitine can be partially effective, the prognosis varies depending on the specific disorder.123
