G6PD (Dublin): chronic non-spherocytic haemolytic anaemia resulting from glucose-6-phosphate dehydrogenase deficiency in an Irish kindred.

Abstract
A new variant of G6PD [glucose-6-phosphate dehydrogenase] associated with chronic non-spherocytic hemolytic anemia (CNSHA) in an Irish male is described. This variant is unique in that it has a normal electrophoretic mobility, km for G6P and NADP, and a normal pH optimum, together with a marked increase in utilization of the substrate 2-deoxyglucose-6-phosphate. It is also relatively heat stable when compared with the normal (B) variant. These characteristics distinguish this variant from previously reported variants associated with CNSHA and it was named G6DP Dublin.
