Abstract
Background The ABO blood group system is clinically important in kidney transplantation, but ABO genotyping fails to attract sufficient attention in some countries and regions. We identified one case of early graft dysfunction due to an ABO genotype mismatch. Here, we performed ABO genotyping in blood samples, analyzed grouping discrepancies, and investigated the weak A subgroup frequency in kidney transplantation candidates. Methods Blood samples from 302 uremic patients with grouping discrepancies and 356 uremic patients with type A blood were analyzed using standard serologic serotyping techniques. The ABO genotypes and alleles were analyzed by polymerase chain reaction sequence-specific primer (PCR-SSP) and sequence-based typing (PCR-SBT). Results All 302 uremic patients with grouping discrepancies carried weak ABO subgroup alleles and 77.48% carried irregular ABO antibodies. The discrepancy rate between serotyping and genotyping was 42.38%, and the mismatching rate of donor selection according to serotype reached 88.74%. And 2.53% of 356 uremic patients with type A blood were determined to be in the weak A subgroup, which was a higher percentage than that observed in the healthy Chinese population (0.53%) by serological screening, but much lower than that observed in Caucasians (20%). Conclusion We revealed the high risk of blood type misjudgment and genetically ABO-mismatched transplantation if serological test was performed only in blood-group typing. Improved precision of ABO genotyping is crucial for successful kidney transplantation and reasonable organ allocation.

Abstract
Background Individuals with the CisAB phenotype are rare in the Chinese population. In the present study, we investigated the sequence of the ABO gene and family members of a newborn suspected to have the CisAB phenotype. Methods The ABO phenotype was detected using conventional serological tests. The full coding region of exons 1 to 7 of the ABO gene was amplified by polymerase chain reaction and was sequenced. The ABO haplotype was determined by the allele-specific primer sequencing method. Results The proband and his father and grandfather were assigned the CisAB phenotype according to the results of the serological tests and family investigation. A novel CisAB allele was identified in the proband and his father and grandfather, which has only one nucleotide difference at position 796 from A to C (c.796A>C) compared with the ABO*B.01 allele. Conclusion A novel CisAB (c.796A>C mutation in ABO*B.01) allele is the first identified in the Chinese population.
