Main clinical features
  • lactic acidemia in the neonatal period with serum lactate levels ranging from 2.5 to 17 mM; failure of dichloroacetate to activate the PDH complex in skin fibroblasts was evident, with complete absence of PDP1 protein in mitochondria
  • lactic acidemia with pyruvate dehydrogenase phosphatase deficiency, defect, which was apparent in muscle and liver but not in brain, with markedly reduced activity of pyruvate dehydrogenase phosphatase
  • Genetic determination autosomal recessive
    Function/system disorder metabolism/carbohydrates
