Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting).

2022年9月1日 · Long-chain hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency and trifunctional protein (TFP) deficiency are caused by impairment of mitochondrial TFP. TFP has three enzymatic activities – long-chain enoyl-CoA hydratase, long-chain 3-hydroxyacyl-CoA dehydrogenase, and long-chain 3-ketoacyl-CoA thiolase.

Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Signs and symptoms of LCHAD deficiency typically appear during infancy or …

Deficiency of the mitochondrial trifunctional protein (TFP) and long-chain 3-Hydroxy Acyl-CoA dehydrogenase (LCHAD) impairs long-chain fatty acid oxidation and presents with hypoglycemia, cardiac, liver, eye, and muscle involvement. Without …

Long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency is a rare autosomal recessive fatty acid oxidation disorder [1] that prevents the body from converting certain fats into energy. This can become life-threatening, particularly during periods of fasting. [citation needed]

LCHAD is a type of fatty acid oxidation disorder. People with LCHAD have problems breaking down fat into energy for the body. What Causes LCHAD? Enzymes help start chemical reactions in the body. LCHAD happens when an enzyme called “long chain 3-hydroxyacyl-CoA dehydrogenase” is either missing or not working.

Long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is a rare fatty acid oxidation (FAO) disorder that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). LCHAD is associated with high mortality unless treated promptly.

LCHAD deficiency is an inherited disease characterized by lethargy, weakness, vomiting, and low blood sugar. It can quickly progress to liver problems, seizures, coma, and death if untreated. 1 Individuals with LCHAD deficiency have

LCHADD is caused by the isolated deficiency of long chain 3-hydroxyacyl-CoA dehydrogenase, an enzyme of the mitochondrial trifunctional protein complex (TFP). TFP is a heterooctamer of 4 alpha and 4 beta subunits. LCHADD is due to mutations in the HADHA gene (2p23) which encodes for the alpha subunit of TFP.

Current dietary management of long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD; long-chain- (S)-3-hydroxyacyl-CoA: NAD + oxidoreductase, EC 1.1.1.211) deficiency (LCHADD) is based on avoiding fasting, and minimizing energy production from long-chain fatty acids.
