title: A novel mutation identified in carnitine palmitoyltransferase II deficiency.
abstract: Carnitine palmitoyltransferase II (CPT II) deficiency is an autosomal recessive disorder of mitochondrial fatty-acid oxidation which presents as three distinct phenotypes (neonatal, infantile, and adult onset). CPT II exons from an adult-onset CPT II-deficient patient were amplified and directly sequenced to further investigate the molecular basis of this disorder. A novel mutation, C471T, in exon 4 of the carnitine palmitoyltransferase II gene was found which created a stop codon, TGA, at residue 124 of the protein (R124Stop). This mutation would result in severe protein truncation. This unique mutation was found on one allele while the S113L mutation, previously reported, was present on the other allele.
