Genes affected
CPT1A (HGNC:2328): (carnitine palmitoyltransferase 1A) The mitochondrial oxidation of long-chain fatty acids is initiated by the sequential action of carnitine palmitoyltransferase I (which is located in the outer membrane and is detergent-labile) and carnitine palmitoyltransferase II (which is located in the inner membrane and is detergent-stable), together with a carnitine-acylcarnitine translocase. CPT I is the key enzyme in the carnitine-dependent transport across the mitochondrial inner membrane and its deficiency results in a decreased rate of fatty acid beta-oxidation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Carnitine palmitoyl transferase 1A deficiency Pathogenic:3Other:1

Labcorp Genetics (formerly Invitae), Labcorp
Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 710 of the CPT1A protein (p.Gly710Glu). This variant is present in population databases (rs80356780, gnomAD 0.006%). This missense change has been observed in individual(s) with carnitine palmitoyltransferase 1A deficiency (PMID: 11350183). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 9071). 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 expected to disrupt CPT1A protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects CPT1A function (PMID: 11350182). For these reasons, this variant has been classified as Pathogenic. -
