摘要：
A novel HLA-B allele, B*5610, has been identified in a potential bone marrow donor, his mother and brother using DNA-based typing and molecular cloning methods. The B*5610 allele differs from the closest matching HLA sequence of B*5602 by two nucleotide substitutions in exon 3, 559 C-->A and 560 T-->C, resulting in an amino acid change from Leu (CTG) to Thr (ACG) at codon 187. This new allele was segregated together with A*24020101 and DRB1*140101 in the proband's family. Serology study revealed that B*5610 is associated with B22 specificity. A PCR-SSP method was developed to distinguish B*5610 from other B*56 alleles. No further individuals with B*5610 were detected in 5000 Chinese bone marrow blood donors.
