Haemolytic disease of the newborn due to Rhesus anti-e antibody

Haemolytic disease of the newborn due to rhesus anti-e alone is a rare occurrence. This condition is described in the second child of an R2R2 mother who had not previously been transfused. The antibody was of IgG subclasses IgG1 + IgG3 and was detectable on the baby's cells for 4 months after birth. The anaemia was mild and persisted for the same period.
