Genes affected
CPT2 (HGNC:2330): (carnitine palmitoyltransferase 2) The protein encoded by this gene is a nuclear protein which is transported to the mitochondrial inner membrane. Together with carnitine palmitoyltransferase I, the encoded protein oxidizes long-chain fatty acids in the mitochondria. Defects in this gene are associated with mitochondrial long-chain fatty-acid (LCFA) oxidation disorders. [provided by RefSeq, Jul 2008]

Carnitine palmitoyltransferase II deficiency Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 23, 2024 | This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 170 of the CPT2 protein (p.Leu170Arg). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with CPT2-related conditions. ClinVar contains an entry for this variant (Variation ID: 529863). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
