Next-generation sequencing (NGS) at the HLA-A, -B, -C, -DRB1, -DRB3/4/5, -DQA1, -DQB1, -DPA1, and -DPB1 loci was performed on 5,266 southern Chinese unrelated donors of the Hong Kong Bone Marrow Donor Registry. 1). Each version release includes a list of newly deposited sequences and allele reports. This database is foundational for many HLA Typing algorithms and Next Generation sequencing projects.

Resulting allele frequencies were reported at 3-field unless there was an allele with “N” or all samples could be resolved at 4-field for that allele or the allele was given with only 2-field resolution in HLA … Learn about genetic conditions, genes, chromosomes, and more.
