Glucose-6-phosphatase 3, also known as glucose-6-phosphatase beta, is an enzyme that in humans is encoded by the G6PC3 gene.^[3][4][5]

Function

This gene encodes the catalytic subunit of glucose 6-phosphatase (G6Pase). G6Pase is located in the endoplasmic reticulum (ER) and catalyzes the hydrolysis of glucose 6-phosphate to glucose and phosphate in the last step of the gluconeogenic and glycogenolytic pathways.^[3]

Clinical significance

Mutations in this gene result in autosomal recessive severe congenital neutropenia.^[3]
