Introduction to Phosphoglycerate Kinase 1 Deficiency
Phosphoglycerate kinase 1 deficiency٫ also known as glycogenosis type 9٫ is a metabolic muscle disease that impacts energy production from carbohydrates. It is caused by mutations in the PGK1 gene٫ affecting ATP production in glycolysis.
What is Phosphoglycerate Kinase 1 Deficiency?
Phosphoglycerate kinase deficiency, also known as glycogenosis type 9, is a metabolic muscle disease impacting energy production. It stems from mutations in the PGK1 gene, hindering ATP creation in glycolysis. Symptoms may include anemia, enlarged spleen, mental retardation, and epilepsy. The condition results from a lack of the enzyme phosphorylase b kinase, affecting glycogen breakdown. PGK1 is crucial for ATP generation in aerobic glycolysis and plays roles in various biological processes like angiogenesis and DNA repair. This rare X-linked disorder presents as hemolytic anemia, myopathy, and neurological dysfunctions. Less than a hundred cases have been reported since its discovery in 1968. Some patients experience chronic hemolytic anemia, muscle weakness, and intellectual disability. Mutations in the PGK1 gene cause the deficiency, impacting glucose metabolism and leading to a range of clinical manifestations such as myopathy, anemia, and neurologic issues. The disease has a highly variable clinical phenotype, with symptoms including hemolytic anemia, intellectual disability, and muscle problems.
