The objective of this study is to establish the genotyping methods of new HLA gene, TAP1 and TAP2, and determine the genetic polymorphisms for database study in Koreans before using in clinical laboratory. Polymerase chain reaction- Restriction Fragment Length Polymorphism (PCR-RFLP) and PCR-Sequence Specific Primers (PCR-SSP) techniques were used for TAP1 and TAP2 genotying, respectively. Restriction enzymes, Bcll and Accl, and 4 oligonucleotide primers were used for the PCR-RFLP analysis of TAP1. Whereas for PCR-SSP assay of TAP2, 12 oligonucleotide primers were synthesized. The results of control cells were correlated well with the types which were analyzed at Xlth histocompatibility international workshop. Arnong three and six different alleles of TAP1 and TAP2 found in 200 unrelated Korean individuals, TAP1A (84%) was the most frequent allele. TAP1B and TAP1C were 15.5% and 0.5% respectively. TAP2A represented more than a half (55.1%). TAP2B and TAP2C were 32.2% and 9.2% respectively. TAP1D, TAP2F and TAP2G were not found in Koreans
