Carnitine palmitoyltransferase II deficiency is an inherited disorder of mitochondrial long-chain fatty acid oxidation. There is a spectrum of severity.
Well established gene-disease association, multiple families reported.
Evidence for mono-allelic variants causing mild, adult-onset disease is limited (most of those with later onset have had bi-allelic variants).Created: 22 Nov 2021, 2:09 a.m. | Last Modified: 22 Nov 2021, 2:09 a.m.

PMID: 31541997 - One child with exercise-induced weakness, mild muscle hypotonia and slightly elevated CK levels. Patient was chet for two missense variants.
PMID: 30149802 - One family (two children) with recurrent rhabdomyolysis associated with transient muscle weakness after prolonged exercise. Patients had elevated CK levels. Carrier parents were normal. Patients were chet for two missense variants, one variant (p.Ser113Leu) is common in gnomAD but 14x pathogenic in ClinVar, recurring pathogenic variant.
PMID: 11585077 - One child with acute muscular weakness, patient was homozygous for the recurring missense (p.Ser113Leu)
