THE PELGER‐HUET ANOMALY: INVESTIGATION OF FAMILY ‘A’

A family showing the Pelger‐Huët anomaly of the neutrophil polymorphonuclear leucocytes is described, the first to be reported in England. Thirty‐four affected individuals have been examined; thirty‐one of these and thirty‐eight unaffected people, either parents or sibs of affected members, have been grouped for the ABO, MNS, Eh, P, Lewis, Kell, Lutheran and Duffy blood‐group systems. No linkage was demonstrated.
