Frequency of MNSs blood groups in south eastern Nigeria.
A total of 614 inhabitants of Calabar, south eastern Nigeria were tested with anti-M, anti-N and anti-S sera to determine the frequency of MNSs blood groups in that population. The results showed that neither ABO blood group nor sex has influence on the occurrence of MNSs blood groups in the population. It was also observed that whereas S antigen was more frequently associated with M antigen, s associated more frequently with N antigen. One half of the Su antigen occurred with MN phenotype. Significantly, the Su antigen occurred in 94% of the male subjects.
