title: Bone marrow donor routine HLA typing identified a novel B*07 allele, B*0734, confirmed by allele-specific DNA cycle sequencing.
abstract: In this article, we report the identification of a new human leukocyte antigen-B allele in a sample that was tested in our routine typing for bone marrow donors. This novel allele officially designed B*0734 was found in a female donor of Bavarian Caucasoid origin (Laboratory code 121036). The search for unrelated bone marrow donors was initiated by the Aktion Knochenmarkspende Bayern. In comparison to the common B*070201, B*0734 differs at four nucleotide positions, 412 (G-->A), 539 (G-->T), 559 (G-->A) and 560 (A-->C) causing three amino acid substitutions, at postion 138 Asp-->Asn, at position 180 Arg-->Leu and at position 187 Glu-->Thr.
