Three newly identified HLA-B alleles: B*5124, B*5306, B*5307 and confirmation of B*0809 and B*5606.

Five HLA-B sequences are described which have been detected as irregular patterns during routine molecular typing. Sequencing of HLA-B exon 2 and 3, both heterozygous and after group specific amplification, revealed three new HLA-B alleles: B*5124, B*5306 and B*5307, whereas the sequences of B*0809 and B*5606 were confirmed. Serological typing showed that B*0809 is expressed as a regular B8, B*5124 as a regular B51, B*5306 as a B51/B53-like variant and B*5606 as a B"blank"-Bw6.
