摘要
The Dombrock blood group system consists of two antithetical antigens, Do(a) (DO1) and Do(b) (DO2), and seven high-prevalence antigens, Gy(a) (DO3), Hy (DO4), Jo(a) (DO5), DOYA (DO6), DOMR (DO7), DOLG (DO8) and DOLC (DO9). Do(a) /Do(b) polymorphism is associated with c.793A>G (p.Asn265Asp) in exon 2 of the DO (ART4) gene, and the corresponding alleles are named DO*01 and DO*02. The rare Donull or Gy(a-) phenotype lacks all Dombrock antigens, and the DO null alleles vary with both DO*01 and DO*02 backgrounds. We report a novel DO null allele, which has a c.268C>T (p.Gln90Stop) nonsense mutation with a DO*02 background identified from four unrelated Gy(a-) Japanese individuals.
