Short-chain acyl-coenzyme A dehydrogenase deficiency affected infants will have vomiting, low blood sugar, a lack of energy , poor feeding, and failure to gain weight and grow. Additional features of this disorder may include poor muscle tone ( hypotonia ), seizures, developmental delays, and microcephaly .
Very long-chain acyl-coenzyme A dehydrogenase deficiency is a fatty-acid metabolism disorder which prevents the body from converting certain fats to energy, particularly during periods without food. [1] [2] [3] Those affected by this disorder have inadequate levels of an enzyme that breaks down a group of fats called very long-chain fatty acids.
Isobutyryl-coenzyme A dehydrogenase deficiency is a rare metabolic disorder in which the body is unable to process certain amino acids properly. [1]People with this disorder have inadequate levels of an enzyme that helps break down the amino acid valine, resulting in a buildup of valine in the urine, a symptom called valinuria.
LCHAD deficiency Long-chain 3-hydroxyacyl-coenzyme; A dehydrogenase deficiency has an autosomal recessive pattern of inheritance. 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.
Medium-chain acyl-CoA dehydrogenase deficiency (MCAD deficiency or MCADD) is a disorder of fatty acid oxidation that impairs the body's ability to break down medium-chain fatty acids into acetyl-CoA. The disorder is characterized by hypoglycemia and sudden death without timely intervention, most often brought on by periods of fasting or vomiting.
3-hydroxyacyl-coenzyme A dehydrogenase deficiency is a rare condition that prevents the body from converting certain fats to energy, particularly during fasting. [1] Normally, through a process called fatty acid oxidation , several enzymes work in a step-wise fashion to metabolize fats and convert them to energy.
This gene encodes a tetrameric mitochondrial flavoprotein, which is a member of the acyl-CoA dehydrogenase family. This enzyme catalyzes the initial step of the mitochondrial fatty acid beta-oxidation pathway. The ACADS gene is associated with short-chain acyl-coenzyme A dehydrogenase deficiency. [6] [5]
ACADVL is linked with very long-chain acyl-coenzyme A dehydrogenase deficiency (VLCADD), which has many symptoms, and typically presents as one of three phenotypes. The first is severe, with an early childhood onset and high mortality rate; the most common symptom is this form is cardiomyopathy. The second is a late onset childhood form, with ...
