We used a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for DNA-based typing of Duffy, Yt and Colton blood groups in Taiwanese, Filipinos and Thais. A total of 200 Taiwanese, 115 Filipinos and 105 Thais were studied. In the Duffy blood group in Taiwanese, 180 cases (90%) were homozygote of Fya, 18 cases (9%) were double heterozygote of Fya and Fyb, and 2 cases (1%) were homozygote of Fyb. In Filipinos, 98 cases (85.2%) were homozygote of Fya, 16 cases (14.0%) were double heterozygote of Fya and Fyb and 1 case (0.8%) was homozygote of Fyb. In Thais, 87 cases (82.9%) were homozygote of Fya, 18 cases (17.1%) were double heterozygote of Fya and Fyb, and no case of Fyb was found. These results correlate well with serological phenotype. For the Yt blood group, only YT1 was found in Taiwanese. Among Filipinos, 114/115 (99.1%) was YT1/1 and 1/115 (0.9%) was YT1/2. In Thais, 103/105 (98.1%) was YT1/1 and 2/105 (1.9%) was YT1/2. For the Colton blood group, the results showed that there was only Coa allele in these three populations. Our results provide the first data of the Yt and Colton blood groups in these three populations.
