Summary
Inborn errors in gluconeogenesis, vital for blood glucose balance, affect key enzymes. This review covers fructose-1,6-bisphosphatase and phosphoenolpyruvate carboxykinase deficiencies.
Area of Science:
- Biochemistry
- Metabolic Disorders
- Genetics
Background:
- Gluconeogenesis is critical for maintaining normoglycaemia during fasting.
- Inborn errors of four key gluconeogenic enzymes are known.
- These enzymes ensure unidirectional flux from pyruvate to glucose.
Purpose of the Study:
- To review the clinical picture, pathophysiology, diagnostic tests, genetics, treatment, and prognosis of specific gluconeogenic enzyme deficiencies.
Main Methods:
- Literature review of deficiencies in fructose-1,6-bisphosphatase and phosphoenolpyruvate carboxykinase.
Main Results:
- Deficiencies in fructose-1,6-bisphosphatase and phosphoenolpyruvate carboxykinase present with distinct clinical and pathophysiological features.
- Diagnostic approaches, genetic underpinnings, and therapeutic strategies vary for these conditions.
Conclusions:
- Understanding these deficiencies is crucial for timely diagnosis and effective management.
- Further research into treatment and prognosis is warranted.
