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:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 13, 2022This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 411 of the CPT2 protein (p.Thr411Met). This variant is present in population databases (rs375957043, gnomAD 0.01%). 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: 576519). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CPT2 protein function. 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. -
