Abstract excerpt
We identified five different alleles, tentatively named ABO*O301, *0302, *R102, *R103, and *A110, in Japanese individuals possessing the blood group O phenotype. These alleles lack the guanine deletion at nucleotide position 261 which is shared by a majority of O alleles. Nucleotide sequence analysis revealed that *0301 and *0302 had single nonsynonymous substitutions compared with *A101 or *A102 responsible for...
