Sequence of a novel HLA-B*51 allele in a volunteer haematopoietic stem cell donor.

Summary We describe a novel HLA-B*51 allele detected by DNA direct sequencing. The sequence of this allele has been officially named B*51:78 as a confirmatory sequence. This new allele nucleotide sequence differs from HLA-B*51:01:01 for two point mutations in exon 2 where codons 79–80 change from CGG-ATC to CGC-ACC (p.Ile80Thr).
