Introduction A trimethylated amino acid, roughly similar in structure to choline, L-carnitine is a cofactor required for transformation of free long-chain fatty acids into acylcarnitines, and for their subsequent transport into the mitochondrial matrix, where they undergo beta-oxidation for cellular energy production. Conditions that appear to benefit from exogenous supplementation of L-carniti...
Systemic carnitine deficiency (SCD) is a rare autosomal recessive disease resulting from defects in the OCTN2 (SLC22A5) gene, which encodes the high-affinity plasma membrane carnitine transporter. Although OCTN2 is fairly well studied in its relationship with SCD, little is known about the carrier frequency of disease-causing alleles of OCTN2, or of more common functional polymorphisms in this ...
Background: Type 1 diabetes mellitus increases the risk of coronary heart disease. The Pittsburgh IDDM morbidity and mortality study reported greater than 10 fold coronary heart disease mortality compared with US national data [1]. Adults with diabetes have heart disease death rates 2 to 4 times higher than adults without diabetes [2]. Diabetic cardiomyopathy explains much of this survival diff...
PURPOSE To describe the MR imaging findings in five children with proved L-carnitine deficiency. METHODS MR imaging studies (five without contrast, two with contrast) were obtained in five children (mean age, 9 years) who presented with stroke symptoms and who proved to have L-carnitine deficiency as established by serum levels. RESULTS In three of five patients, infarctions were confined t...
Primary systemic carnitine deficiency is caused by homozygous or compound heterozygous mutation in the SLC22A5 gene on chromosome 5q31. The most common presentations are in infancy and early childhood with either metabolic decompensation or cardiac and myopathic manifestations. We report a case of 9-year-old boy with dysmorphic appearance and hypertrophic cardiomyopathy. Tandem MS spectrometry ...
Carnitine deficiency syndrome is a rare and potentially fatal but treatable metabolic disorder. I present a 6-year-old girl with primary systemic carnitine deficiency (SCD) proved by very low plasma carnitine level. Her major clinical features included neonatal metabolic acidosis, epilepsy, recurrent infections, acute encephalopathy, and dilated cardiomyopathy with heart failure before 4 years ...
