Carnitine deficiency has been extensively studied, although most commonly as a secondary finding to other metabolic conditions. [5] The first case of SPCD was reported in the 1980s, in a child with fasting hypoketotic hypoglycemia that resolved after treatment with carnitine supplementation.
Carnitine-acylcarnitine translocase deficiency has an autosomal recessive pattern of inheritance. Carnitine-acylcarnitine translocase deficiency is a rare, autosomal recessive metabolic disorder that prevents the body from converting long-chain fatty acids into energy, particularly during periods without food.

SLC22A5 is a membrane transport protein associated with primary carnitine deficiency.This protein is involved in the active cellular uptake of carnitine.It acts a symporter, moving sodium ions and other organic cations across the membrane along with carnitine.
L-Carnitine, acetyl-l-carnitine, and propionyl-l-carnitine are available in dietary supplement pills or powders, with a daily amount of 0.5 to 1 g considered to be safe. [1] [3] It is also a drug approved by the Food and Drug Administration to treat primary and certain secondary carnitine-deficiency syndromes secondary to inherited diseases. [1 ...
2,4-Dienoyl-CoA reductase deficiency was initially described in 1990 based on a single case of a black female who presented with persistent hypotonia. Laboratory investigations revealed elevated lysine, low levels of carnitine and an abnormal acylcarnitine profile in urine and blood.
The primary treatment method for fatty-acid metabolism disorders is dietary modification. It is essential that the blood-glucose levels remain at adequate levels to prevent the body from moving fat to the liver for energy.
Carnitine, a natural substance acquired mostly through the diet, is used by cells to process fats and produce energy. People with this disorder have a faulty enzyme, carnitine palmitoyltransferase I , that prevents these long-chain fatty acids from being transported into the mitochondria to be broken down.
Carnitine palmitoyltransferase II deficiency, sometimes shortened to CPT-II or CPT2, is an autosomal recessively inherited genetic metabolic disorder characterized by an enzymatic defect that prevents long-chain fatty acids from being transported into the mitochondria for utilization as an energy source. The disorder presents in one of three ...
