Abstract
Neutropenia in Glycogen Storage Disease Type Ib (GSDIb) and G6PC3 deficiency results from defects in metabolite repair, leading to the accumulation of 1,5-anhydroglucitol-6-phosphate (1,5-AG6P). Treatment currently relies on inhibitors of SGLT2, the renal sodium-glucose co-transporter, which indirectly enhances urinary excretion of 1,5-anhydroglucitol (1,5-AG), the precursor of the toxic 1,5-AG6P that accumulates in neutrophils and is at the origin of these patients' neutropenia. In this context, a detailed understanding of the formation, intestinal absorption, renal reabsorption, and metabolism of 1,5-AG is essential. Here, we review the current knowledge of these mechanisms, their role in the pathophysiology of 1,5-AG6P–related neutropenia, and explore potential strategies to improve treatment outcomes.
期刊介绍:
The Journal of Inherited Metabolic Disease (JIMD) is the official journal of the Society for the Study of Inborn Errors of Metabolism (SSIEM). By enhancing communication between workers in the field throughout the world, the JIMD aims to improve the management and understanding of inherited metabolic disorders. It publishes results of original research and new or important observations pertaining to any aspect of inherited metabolic disease in humans and higher animals. This includes clinical (medical, dental and veterinary), biochemical, genetic (including cytogenetic, molecular and population genetic), experimental (including cell biological), methodological, theoretical, epidemiological, ethical and counselling aspects. The JIMD also reviews important new developments or controversial issues relating to metabolic disorders and publishes reviews and short reports arising from the Society''s annual symposia. A distinction is made between peer-reviewed scientific material that is selected because of its significance for other professionals in the field and non-peer- reviewed material that aims to be important, controversial, interesting or entertaining (“Extras”).
