Acylcarnitines

Abnormal acylcarnitines accumulate in a variety of inborn errors of metabolism, particularly in fat oxidation defects and certain organic acidurias. Presenting features may include unexplained hypoglycaemia (usually hypoketotic hypoglycaemia), liver disease, metabolic acidosis, cardiomyopathy and muscle weakness.
