ABSTRACT
<p><b>OBJECTIVE</b>To identify a novel human leukocyte antigen (HLA) allele HLA-B*1392 and analyze 3D model of HLA molecule.</p><p><b>METHODS</b>Polymerase chain reaction sequencing-based (PCR-SBT) was used in routine HLA typing, the B locus typing results of one sample was one base mismatch with B*130101, B*580101 at locus 189, The Group Specific Sequencing Products (GSSP) which target at B*13 and B*58 were used to confirm difference between the new allele and highest homologous allele, then the new allele was modeled by Swiss-model to its 3D structure.</p><p><b>RESULTS</b>The sequencing results showed that the new allele with highest homologous allele B*130101 was the difference in the second exon at position 189 C>A (codon 39 GAC>GAA), 39 Asp (D) was changed to Glu (E). The amino acid substitution at residue 39 of the HLA polypeptide was located in α-helices of antigenic peptide-biding region.</p><p><b>CONCLUSION</b>This allele is a new HLA-B allele found in Chinese Guangxi Zhang population and has been designated as HLA-B*1392 by the World Health Organization (WHO) HLA Nomenclature Committee.</p>
