The prevalence of Dia, Mia, and Mur antigens among Malaysians and Indians.

Sir, Low‐incidence red cell antigens can be defined as those which are known to occur in <1% of individuals in most populations. The Dia antigen of Diego blood group system has a low incidence among Caucasians but occurs commonly among Asians of Mongoloid origin.[1] Anti‐Dia has been known to cause hemolytic disease of newborn and delayed hemolytic transfusion reactions. The Mia and Mur are low frequency antigens belonging to the Miltenberger subsystem of MNSs blood group system. Incidence of anti‐Mia and Mur antibodies has been mostly reported among Chinese population, and they are implicated in hemolytic disease of fetus and newborn. The present report gives the prevalence of Dia antigen, Mia, and Mur antigens among voluntary blood donors of Malaysia and India.
