Mutations of OCTN2, an organic cation/carnitine transporter, lead to deficient cellular carnitine uptake in primary carnitine deficiency.
Systemic primary carnitine deficiency (CDSP, OMIM 212140) is an autosomal recessive disease characterized by low serum and intracellular concentrations of carnitine. CDSP may present with acute metabolic derangement simulating Reye's syndrome within the first 2 years of life. After 3 years of age, patients with CDSP may present with cardiomyopathy and muscle weakness. A linkage with D5S436 in 5...
متن کاملAbnormal sodium stimulation of carnitine transport in primary carnitine deficiency.
Primary carnitine deficiency is an autosomal recessive disorder of fatty acid oxidation characterized by hypoketotic hypoglycemia and skeletal and cardiac myopathy. It is caused by mutations in the sodium-dependent carnitine cotransporter OCTN2. The majority of natural mutations identified in this and other Na(+)/solute symporters introduce premature termination codons or impair insertion of th...
متن کاملPrimary Carnitine Deficiency and Cardiomyopathy
Carnitine is essential for the transfer of long-chain fatty acids from the cytosol into mitochondria for subsequent β-oxidation. A lack of carnitine results in impaired energy production from long-chain fatty acids, especially during periods of fasting or stress. Primary carnitine deficiency (PCD) is an autosomal recessive disorder of mitochondrial β-oxidation resulting from defective carnitine...
متن کاملSystemic primary carnitine deficiency with hypoglycemic encephalopathy
Acute hypoglycemia in children is not an uncommon disease that can be encountered in the Emergency Department. Most cases of childhood hypoglycemia are caused by ketotic hypoglycemia due to missed meals. Often, hypoketotic hypoglycemia can also occur, which suggests hyperinsulinemia or a defect in fatty acid oxidation. Carnitine is essential for long chain fatty acids transfer into mitochondria...
متن کاملDiabetic Cardiovascular Risk and Carnitine Deficiency
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...
