Some may have carnitine deficiency secondary to another metabolic condition or due to maternal carnitine deficiency. Proper follow-up of newborn screening results for low free carnitine includes studies of the mother to determine whether her carnitine deficiency is due to SPCD or secondary to a metabolic disease or diet.

Carnitor - an L-carnitine supplement that has shown to improve the body's metabolism in individuals with low L-carnitine levels. It is only useful for Specific fatty-acid metabolism disease. It is only useful for Specific fatty-acid metabolism disease.
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]
Signs and symptoms of this disorder include low levels of ketones (hypoketosis) and low blood sugar (hypoglycemia). Together these signs are called hypoketotic hypoglycemia. People with this disorder typically also have an enlarged liver (hepatomegaly), muscle weakness, and elevated levels of carnitine in the blood. [2]
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 ...
The symptoms and outcome of the disease can be drastically improved by replacement therapy with L-carnitine. [15] The estimated incidence of primary carnitine deficiency in newborns is about 1 in 40,000. [16]
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 ...
