Determination of Granulocyte–Specific Antigens on Neutrophil FcÁ Receptor IIIb by PCR–Preferential Homoduplex Formation Assay, and Gene Frequencies in the Japanese Population

Abstract

The PCR-PHFA method can be semi-automated easily with computer-based assignment and is suitable for typing both small and large numbers of samples. In the Japanese population, the frequency of NA1 is about double that in Caucasians (32.5%), and the SH allele is rare.
