ABSTRACT
Objective:
To confirm the novel allele HLA-A*01∶130 and analyzed the nucleotide sequence of the abnormal reaction pattern.Methods:
The HLA typing of sample DNA was performed by PCR-SBT.The ambiguous novel HLA allele was confirmed with single stranded SBT method,then DNA sequencing was performed to identify the difference between the novel allele and HLA-A?0166 allele.Finally, it was modeled by Swiss-Model to three-dimensional structure of HLA Molecule.Results:
The novel allele was not the same with all known HLA-A allele sequence.After analysis,there was one nucleotide differed from the A?0166 at position 368 where A→G( codon 99 TAT→TGT) resulting in a coding change,99 Tyr was changed to Cys.The amino acid substitution at residue 99 the HLA polypeptide was located in a beta-sheet of antigenic peptide-binding region.Conclusion:
The allele is a novel allele that has now been officially named as HLA-A*01∶130 by the World Health Organization( WHO) HLA Nomenclature Committee.
