Non‐spherocytic Haemolytic Anaemia in Mother and Son Associated with Hexokinase Deficiency

Abstract

The case history, laboratory findings and properties of the enzyme in a patient with hexokinase deficiency are reported. The mother had a haemolytic disorder of similar severity. In these cases the expression of the disease in both mother and son suggests a dominant mode of inheritance. This family further illustrates the necessity of taking the reticulocyte level into account when interpreting red cell enzyme levels.
