New DRB1 alleles (HLA-DRB11135, DRB11430 and DRB11433) and a confirmatory sequence (DRB11133)

Three new DRB1 alleles (DRB1*1135, DRB1*1430 and DRB1*1433) and a confirmatory sequence (DRB1*1133) have been identified after following up unusual or novel polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) patterns during routine typing of the DRB1*03,*08,*11,*12,*13 and *14 allele groups. Of the new alleles found and described in this paper, two alleles were initially detected by the PCR‐RFLP method which produced unexpected restriction polymorphism (DRB1*1133 and DRB1*1135) while the remaining two were found after following up rare allele typings from this technique (DRB1*1430 and DRB1*1433).
