MSH: An autosomal recessive metabolic disorder caused by absent or decreased PYRUVATE CARBOXYLASE activity, the enzyme that regulates gluconeogenesis, lipogenesis, and neurotransmitter synthesis. Clinical manifestations include lactic acidosis, seizures, respiratory distress, marked psychomotor delay, periodic HYPOGLYCEMIA, and hypotonia. The clinical course may be similar to LEIGH DISEASE. (From Am J Hum Genet 1998 Jun;62(6):1312-9),NCI: A rare autosomal recessive inherited metabolic disorder caused by mutations in the PC gene. It results in the accumulation of lactic acid and other toxic substances in the blood. Signs and symptoms appear early in life and include failure to thrive, mental and growth retardation, motor disturbances, seizures, and lactic acidosis.
