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.

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 ...
Carnitine deficiency is found in about 50% of cases. [18] Over 90% of those diagnosed with 3-Methylcrotonyl-CoA carboxylase deficiency by newborn screening remain asymptomatic. The medical abnormalities that present in the few who do show symptoms are not always clearly related to 3-Methylcrotonyl-CoA carboxylase deficiency. [5]
Treatment for all forms of this condition primarily relies on a low-protein diet, and depending on what variant of the disorder the individual suffers from, various dietary supplements. All variants respond to the levo isomer of carnitine as the improper breakdown of the affected substances results in sufferers developing a carnitine deficiency ...
Carnitine Transport Defect; Carnitine-acylcarnitine translocase deficiency (CACT) Carnitine Palmitoyl Transferase I & II ( CPT I deficiency & CPT II deficiency) 2,4 Dienoyl-CoA Reductase Deficiency; Electron Transfer Flavoprotein (ETF) Dehydrogenase Deficiency (GA-II/MADD) 3-Hydroxy-3-methylglutaryl-CoA lyase deficiency (HMG deficiency)
A disorder is associated with carnitine-acylcarnitine translocase deficiency.This disorder disrupts the carnitine shuttle system from moving fatty acids across the mitochondrial membrane, leading to a decrease in fatty acid catabolism.
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.
