| Abstract | Human leucocyte antigen (HLA) alleles and haplotypes differ significantly among different ethnic groups, and high-resolution typing methods allow for the detection of a wider spectrum of HLA variations. In this study, HLA-A, -B and -DRB1 genotypes were analysed in 4128 cord blood units obtained from Korean women using the sequence-based typing method. A total of 44 HLA-A, 67 HLA-B and 48 HLA-DRB1 most probable alleles were identified. Of these, high-frequency alleles found at a frequency of ≥5% were 6 HLA-A (A*02:01, A*02:06, A*11:01, A*24:02, A*31:01, A*33:03), 5 HLA-B (B*15:01, B*44:03, B*51:01, B*54:01, B*58:01) and 7 HLA-DRB1 (DRB1*01:01, DRB1*04:05, DRB1*07:01, DRB1*08:03, DRB1*09:01, DRB1*13:02, DRB1*15:01) alleles. At each locus, A*02, B*15 and DRB1*04 generic groups were most diverse at allelic level, consisting of 8, 11 and 10 different alleles, respectively. Two- and three-locus haplotypes estimated by the maximum likelihood method revealed 73 A-B, 74 B-DRB1 and 42 A-B-DRB1 haplotypes with frequencies of ≥0.3%. A total of 193 A-B-DRB1 haplotypes found at a frequency of ≥0.1% were presented, and the six most common haplotypes were A*33:03-B*44:03-DRB1*13:02 (4.6%), A*33:03-B*58:01-DRB1*13:02 (3.0%), A*24:02-B*07:02-DRB1*01:01 (2.7%), A*33:03-B*44:03-DRB1*07:01 (2.5%), A*30:01-B*13:02-DRB1*07:01 (2.2%) and A*24:02-B*52:01-DRB1*15:02 (2.1%). Compared with previous smaller scale studies, this study further delineated the allelic and haplotypic diversity in Koreans including low-frequency alleles and haplotypes. Information obtained in this study will be useful for the search for unrelated bone marrow donors and for anthropologic and disease association studies. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
