MITOCHONDRIAL COMPLEX III DEFICIENCY, NUCLEAR TYPE 6; MC3DN6

Description

Mitochondrial complex III deficiency nuclear type 6 (MC3DN6) is an autosomal recessive disorder caused by mitochondrial dysfunction. It is characterized by onset in early childhood of episodic acute lactic acidosis, ketoacidosis, and insulin-responsive hyperglycemia, usually associated with infection. Laboratory studies show decreased activity of mitochondrial complex III. Psychomotor development is normal (summary by Gaignard et al., 2013).For a discussion of genetic heterogeneity of mitochondrial complex III deficiency, see MC3DN1 (OMIM ).

Most common symptoms of MITOCHONDRIAL COMPLEX III DEFICIENCY, NUCLEAR TYPE 6; MC3DN6

  • Encephalopathy
  • Acidosis
  • Elevated hepatic transaminase
  • Lactic acidosis
  • Hepatic failure

ISOLATED COMPLEX III DEFICIENCY

Alternate names

ISOLATED COMPLEX III DEFICIENCY Is also known as isolated coq-cytochrome c reductase deficiency, isolated ubiquinone-cytochrome c reductase deficiency, isolated mitochondrial respiratory chain complex iii deficiency, isolated coenzyme q-cytochrome c reductase deficiency

Description

Isolated complex III deficiency is a rare, genetic, mitochondrial oxidative phosphorylation disorder characterized by a wide spectrum of clinical manifestations ranging from isolated myopathy or transient hepatopathy to severe multisystem disorder (that may include hypotonia, failure to thrive, psychomotor delay, cardiomyopathy, encephalopathy, renal tubulopathy, hearing impairment, lactic acidosis, hypoglycemia and other signs and symptoms).

Most common symptoms of ISOLATED COMPLEX III DEFICIENCY

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Short stature
  • Generalized hypotonia
