Identification of the novel HLA-A*9250 allele by sequence-based typing in a Caucasian bone marrow donor from Italy

HLA-A*9250 allele was identified by SBT in a Caucasian bone marrow donor. It differs from the closest A*020101 by only one nucleotide (A -> G) at position 124 in exon 2 (Arg to Gly at codon 18); this is an uncommon variation at a highly conserved nucleotide position, located on the loop between S1-S2 beta-sheets in alpha 1 domain.
