PDH deficiency is an X linked disease that shows heterogeneous characteristics in both clinical presentation and biochemical abnormality. The PDH Complex is a multi enzyme complex that plays a vital role as a key regulatory step in the central pathways of energy metabolism in the mitochondria. Inheritance and pathophysiology The most commonly seen form of PyruvateDehydrogenase Complex Deficiency is caused by mutations in the X linked E1 alpha gene and is approximately equally prevalent in both males and females. However, a greater severity of symptoms tends to affect males more often than heterozygous females. This can be explained by x inactivation , as females carry one normal and one mutant gene. Cells with a normal allele active can metabolize the lactic acid that is released by the PDH deficient cells. They cannot, however, supply ATP to these cells and, therefore, phenotype depends largely on the nature severity of the mutation. ref name PMC1016663 cite journal author G K Brown, L J Otero, M LeGris, and R M Brown title Pyruvatedehydrogenasedeficiency journal J Med Genet. volume 31 issue 11 pages 875 879 year 1994 month ... ref ref name PMC1801181 cite journal author H H Dahl title Pyruvatedehydrogenase E1 alpha deficiency ... 0006.pdf ref Clinical Presentation PyruvateDehydrogenase Complex Deficiency is generally present ... out. ref name PMC1016663 Treatment Direct treatment that stimulates the pyruvatedehydrogenase complex ... the inhibitory phosphorylation of pyruvatedehydrogenase complex and thereby activates any residual ... of approximately 10 mmol L.

Normally, through a process called fatty acid oxidation , several enzymes work in a step wise fashion to metabolize fats and convert them to energy. People with 3 hydroxyacyl coenzyme A dehydrogenasedeficiency have inadequate levels of an enzyme required for a step that metabolizes groups of fats called medium chain fatty acid s and short chain fatty acid s for this reason this disorder is sometimes called medium and short chain 3 hydroxyacyl coenzyme A dehydrogenase M SCHAD deficiency. Typically, initial signs and symptoms of this disorder occur during infancy or early childhood and can include poor appetite, vomiting, diarrhea, lethargy , hypoglycemia , hypotonia , liver problems, and abnormally high levels of hyperinsulinism . Insulin controls the amount of sugar that moves from the blood into cells for conversion to energy. Individuals with 3 hydroxyacyl coenzyme A dehydrogenasedeficiency are also at risk for complications such as seizures, life threatening heart and breathing problems, coma, and sudden unexpected death. Problems related to 3 hydroxyacyl coenzyme A dehydrogenasedeficiency can be triggered by periods of fasting or by illnesses such as viral infections. This disorder is sometimes mistaken for Reye syndrome , a severe disorder that may develop in children while they appear to be recovering from viral infections such as chicken pox or flu.

People with this disorder have inadequate levels of an enzyme that helps break down the amino acid valine , resulting in a build up of valine in the urine, a symptom called valinuria . Diagnosis Babies with this disorder are usually healthy at birth. The signs and symptoms may not appear until later in infancy or childhood and can include poor feeding and growth failure to thrive , a weakened and enlarged heart dilated cardiomyopathy , seizures, and low numbers of red blood cells anemia . Another feature of this disorder may be very low blood levels of carnitine a natural substance that helps convert certain foods into energy . Isobutyryl CoA dehydrogenasedeficiency may be worsened by long periods without food fasting or infections that increase the body s demand for energy. Some individuals with gene mutations that can cause isobutyryl CoA dehydrogenasedeficiency may never experience any signs and symptoms of the disorder. Genetics Image autorecessive.svg thumb right Isobutyryl coenzyme A dehydrogenasedeficiency has an autosomal recessive pattern of inheritance. Defects in the ACAD8 gene cause isobutyryl coenzyme A dehydrogenasedeficiency. The ACAD8 gene provides instructions for making an enzyme that plays an essential role in breaking down proteins from the diet. Specifically, the enzyme is responsible for processing valine, an amino acid that is part of many proteins. If a mutation in the ACAD8 gene reduces or eliminates the activity of this enzyme, the body is unable to break down valine properly. As a result, poor growth and reduced energy production ... more details
