The use of DNA analyses for subtyping Aend or Bm in ABO blood group system

Abstract We sequenced genomic DNA of Aend and Bm subtypes. Our data showed that sequences of the Aend allele from two of Aend and three of AendB samples were identical to those of A 1 allele. And sequences of the Bm allele from two of Bm and one of ABm samples were identical to those of B allele. These sequence data could not be accepted for subtyping A 1 or B blood group.
