Identification of a new allele, HLA-DRB5*0113, through three different molecular biology techniques

Abstract

A new HLA-DRB5 allele, HLA-DRB5*0113, has been identified in an Italian patient during routine HLA typing in order to activate a bone marrow donor search. HLA typing was performed by different molecular biology techniques, and the results showed that the HLA-DRB5*0113 allele differs from HLA-DRB5*010101 allele for three nucleotide substitutions at codons 57 (GAC-->GAT; Asp) and 58 (GCT-->GAG; Ala-->Glu) of exon 2.
