Glucose-6-phosphate isomerase (GPI) deficiency is very rare, but one of the most common erythroenzymopathies, causing hereditary nonspherocytic hemolytic anemia. This case report describes the clinical features and the molecular etiology of a Dutch patient with GPI deficiency. She is the fifth patient with GPI deficiency identified to date in the Netherlands and was found to be compound heterozygous for the previously reported c.1615G>A p. (Asp539Asn) mutation and a novel c.271A>T p.(Asn91Tyr) variant.
