As the first discovered blood group system, the ABO blood group plays a critical role in blood transfusion and hemolytic disease in newborns. Subgroup phenotypes, such as A2, Aint, A3, cisAB, B3, and Bel, have been found with the weakening of A and/or B antigens or inconsistency between forward and reverse typing. At present, several hundred variant alleles have been identified worldwide from individuals with ABO subgroups. In this report, we describe a novel single nucleotide variant, c. 671T>C, in exon 7 of the ABO gene, which was identified in a Chinese patient.
