Six new HLA class I alleles detected by PCR-SSO genotyping.

This paper describes six new alleles; A*0240, A*2614, B*3924, B*4425, Cw*0807 and Cw*12023, which were discovered during routine genotyping with sequence specific oligonucleotides (SSO's). Five of the new alleles have changes in residues which belong to the antigen binding site of the HLA protein. These new variants may have altered antigen binding properties and may cause differential immunological responses that could affect transplantation outcome1.
