    Abstract:
    Population genetic studies have become an invaluable tool because of the extreme polymorphism found at some of the loci of the human leukocyte antigen (HLA) system. In this study, we are reporting for the first time the genetic polymorphism of 141 healthy unrelated Bangladeshi Bangalees living in central region of Dhaka. We studied the HLA-A, -B and -DRB1 loci using polymerase chain reaction with sequence-specific primers. The allelic frequencies, two and three locus haplotype frequencies were statistically analyzed. A total of 16 HLA-A alleles, 26 HLA-B alleles and 14 HLA-DRB1 alleles were detected. A*33-B*44 (8.15%) was the most common two loci class 1 haplotype, whereas A*33-B*44-DRB1*07 (6.38%) was the most frequent three loci haplotype. The most common HLA-A, HLA-B and HLA-DRB1 alleles were A*33 (17.02%), B*15 (19.5%) and DRB1*15 (29.07%), respectively. Construction of phylogenetic tree using average linkage between groups and correspondence analysis showed close associations with Indian non-tribal random Dravidians, north Indian Hindus and some relations with Mongolian and Pakistani populations. We believe this data will provide useful information for bone marrow registry, legal medicine, disease association and anthropological studies.
