We report the first splice junction mutation to be described in the carnitine palmitoyltransferase (CPT) 2 gene in a patient with the muscle form of CPT II deficiency. The patient, a 25-year-old man, suffered from attacks of myalgia and muscle weakness in early adult life. There was biochemical evidence of CPT II deficiency. Molecular genetic analysis revealed the common S113L mutation on one allele whilst a novel mutation at the splice donor junction in intron 3 was identified on the other allele. Sequencing of reverse transcription polymerase chain reaction (RT-PCR) products clearly demonstrated that this mutation causes the skipping of exon 3, thus establishing its pathogenic role.
