Anti-Rh 29 in a primigravida with rhesus null syndrome resulting in haemolytic disease of the newborn.

This is the first British patient to be reported with the rhesus null phenotype. Anti-Rh 29 was detected in a primigravida at 35 weeks' gestation and rose substantially before delivery. She had all the features of the rhesus null syndrome and her newborn was affected by haemolytic disease (HDN).
