Human Leukocyte Antigen: Class I Allele Frequencies and Haplotype Distribution in a Tertiary Care Hospital in Bangladesh

Human leukocyte antigen (HLA) are cell surface glycoproteins encoded by Major Histocompatibility Complex (MHC) gene of human genome. HLA antigen frequency and haplotype distribution are useful for determining disease association, origin, migration and genetic relationship between populations and predicting the outcome of transplantation. Thus, the present study was carried out to identify HLA class I (HLA-A and HLA-B) antigen and haplotype distribution among a selected Bangladeshi population. This retrospective study was conducted among 1070 individuals, who were referred by clinicians for HLA typing at the Tissue Typing Laboratory of the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU) during the period 2009 to 2011. For HLA typing, blood was collected in heparin containing tube and the laboratory tests were performed by the microlymphocytotoxicity technique according to manufacturer’s instructions.
