Abstract excerpt
Primary carnitine deficiency (PCD) is an autosomal recessive disorder caused by mutations in the SLC22A5 gene, which encodes the organic cation transporter 2 (OCTN2). These mutations impair carnitine transport and fatty acid metabolism, leading to a wide range of clinical symptoms, from mild fatigue to severe cardiomyopathy. Although over 100 mutations have been identified, the correlation between specific...
