Abstract
We here describe the identification of the novel human leukocyte antigen allele HLA-A*02:182 which has been detected in a potential bone marrow donor. The new allele differs from the sequence of HLA-A*02:01:01:01 only by a non-synonymous nucleotide exchange of Guanin (G) → Cytosin (C) at position 199 in exon 3 replacing amino acid (AA) Arginine (Arg, R) by Threonine (Thr, T) in codon 157. Since the HLA-A*02:01:01:01 allele differs from A*02:182 only at AA position 157, it is assumed that the protein structures of these alleles are highly similar. A mismatch between HLA-A*02:01:01:01 and HLA-A*02:182 is predicted to have a very low allogeneic potential in hematopoietic stem cell transplantation. [ABSTRACT FROM AUTHOR]
