Study of the Gregory blood group in an English family.
An example of anti-Gy-a found during routine antenatal testing is the first recorded example in Europe to be described. Five other Gy(a-) siblings were found in the patient's family from whom blood donations were obtained in the event of a needed transfusion. Although anti-Gy-a was detected in the infant's serum, there was no evidence of haemolytic disease of the newborn, presumably due to the fact that the Gy-a antigen is poorly developed at birth.
