3-Ketothiolase deficiency.
European Journal of Pediatrics
|April 1, 1986
Summary
Mitochondrial 3-ketothiolase deficiency causes episodic ketosis and metabolic acidosis in patients. This genetic disorder affects the central nervous system and is characterized by specific organic aciduria.
Area of Science:
- Biochemistry
- Genetics
- Metabolic Disorders
Background:
- Mitochondrial 3-ketothiolase is crucial for fatty acid metabolism.
- Deficiency in this enzyme can lead to severe metabolic disturbances.
Observation:
- Two patients presented with deficient short chain-length-specific mitochondrial 3-ketothiolase activity.
- Other mitochondrial 3-ketothiolase isoenzymes were found to be normal.
Findings:
- Both patients exhibited episodic ketosis and metabolic acidosis.
- Characteristic organic aciduria included 2-methyl-3-hydroxybutyric acid and tiglyglycine.
- One patient showed central nervous system damage, with affected siblings deceased.
Implications:
- This deficiency represents a distinct inherited metabolic disorder.
- Early diagnosis and management are critical for patients with this condition.
- Further research into therapeutic strategies is warranted.
