Some hybrid GP can express Mi<sup>a</sup> antigen, the most common being GP.Mur. Of potential clinical significance in transfusion practice, GYP*Mur homozygotes can produce anti-JENU because they lack expression of the high-frequency JENU antigen. Although serological typing using anti-Mi<sup>a</sup> is very likely to identify GP.Mur, this method cannot reliably distinguish the underlying GP or confirm the zygosity of GP.Mur, which is relevant for transfusion safety.
