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]

The c.1602G>A; p.Glu534Glu variant (rs148110518, ClinVar variant ID 460425) does not alter the amino acid sequence of the CPT2 protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site. This variant has not been reported in medical literature or in gene specific variation databases. This variant is listed in the genome Aggregation Database (gnomAD) with a Latino population frequency of 0.1% (identified on 37 out of 33,984 chromosomes). Based on the available information, the c.1602G>A variant is likely to be benign. -
