Aim: The CPT1A gene encodes carnitine palmitoyltransferase IA, an enzyme involved in fatty acid oxidation in the liver. Homozygous or compound heterozygous variants in the CPT1A gene cause carnitine palmitoyltransferase 1A deficiency. Herein, we report a case with carnitine palmitoyltransferase 1A deficiency caused by a homozygous exonic deletion mutation in CPT1A gene.
