Description

This sequence change creates a premature translational stop signal (p.Trp374*) in the CPT2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CPT2 are known to be pathogenic (PMID: 16781677, 16996287). This variant is present in population databases (rs771486286, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with CPT2-related conditions. For these reasons, this variant has been classified as Pathogenic.
