A clinical and biochemical camouflage-carnitine palmitoyltransferase-1 deficiency: A case series

Carnitine Palmitoyltransferase-1 (CPT-1) deficiency is a rare metabolic disorder of fatty acid oxidation. The presentation of this deficiency is a mixed bag of several clinical and biochemical manifestations which is determined by the tissue-specific isoforms of the enzyme. Presenting in one way, which can be lethal due to cardia complications, another way that this disorder can come to a clinician’s attention is when children manifests with increasing lethargy during intercurrent illnesses. Rarely, but not exclusively, a seizure may be the only presenting complaint along with severe metabolic acidosis. In this case series, we present a discussion of three cases with CPT1 deficiency presenting with a camouflage of various contrasting clinical and biochemical manifestations.
