    Abstract:
    In this study, human leukocyte antigen (HLA) class I and II were examined through sequence-specific primer typing in 176 unrelated individuals from six Malay subethnic groups of Peninsular Malaysia: Kelantan (n = 25), Minangkabau (34), Jawa (30), Bugis (31), Banjar (33), and Rawa (23). The most common HLA alleles in all groups were A*24 (26-41%), Cw*07 (24-32%), B*15 (22-30%), DRB1*12 (15-36%), and DQB1*03 (25-51%). The Malay subethnic groups studied demonstrated a close relationship to each other and to other Asian populations, despite specific differences between them. Banjar, Bugis, and Jawa Malays demonstrated no significant difference from each other, which could be a result of their related origin from the islands around the Java Sea. These three Malay subethnic groups were then collapsed into one group, which also helped to increase the sample number and sharpen statistical results. Minangkabau and Rawa Malays exhibited high similarities in allele group and haplotype frequencies, which could be a consequence of their common origin from Sumatera. Kelantan Malays, in addition to their statistically significant differences compared with the other groups, also exhibited differences on the most frequent haplotypes, which are almost absent in the other subethnic groups studied.
