Most expressed HLA (human leukocyte antigen) loci exhibit a remarkable degree of allelic polymorphism, which derives from sequence differences predominantly localized to discrete hypervariable regions of the amino terminal domain of the molecule. In this study, the HLA-B genotypes were determined in twenty students unrelated koreans using the PCR-SSP (polymerase chain reaction-sequence specific primer) technique. Several specific primer pairs in assigning the HLA-B gene were used ($B^{\ast}4001/4007$, $B^{\ast}4901/5001/4501$, $B^{\ast}3701$, $B^{\ast}5801$). The results of PCR-SSP, the HLA-B3701 primer was detected one (5%), the $HLA-B^{\ast}5801$ were detected four (20%), the $HLA-B^{\ast}4001/4007$ were detected nineteen (95%) and the $HLA-B^{\ast}4901/5001/4501$ were detected twenty. This study shows that the PCR-SSP technique is relatively simple, fast and a practical tool for the determination of the HLA-B genotypes. Moreover, these results genotype frequency of the HLA-B gene could be useful for database study before being applied to individual identification and transplantation immunity.
