Abstract
- B₃ is a rare finding, but it is most common in the B subgroup, which been reported as being 0.025% of the total B group in Koreans. ABO*B3.01 is a specific allele for B₃, a missense mutation with a substituted thymine from cytosine of the 1,054th nucleotide of the ABO*B.01 allele, but rather unexpectedly, it has not been reported in Koreans. We report here the first Korean case of the serological Aâ‚B₃ phenotype with ABO*B3.01, which was confirmed by sequencing of exons 6 and 7 of the ABO gene, found in a pregnant woman.
