Three novel alleles at the HLA-DRB1 locus identified by sequence-based typing.

We describe here the sequences of 3 new HLA-DRB1 variants officially named DRB1*03:05:03, DRB1*11:10:02, and DRB1*14:86. These novel alleles have been detected in 3 Caucasoid individuals by sequence-based typing. The first and second alleles are the result of a silent mutation, which does not imply any amino acid change.
