Abstract:
To analyse the reason for one case of hemolytic transfusion reaction, antibodies in a patient's serum were identified using panel cells and Le (a-b-) phenotype cells, patient phenotype was identified by using anti-Le(a) and anti-Le(b) blood grouping reagents and the entire coding region of FUT3 gene was amplified by PCR and sequenced directly. The results showed that both IgM anti-Le(a) and anti-Le(b) antibodies were detected in patient's serum. Red cells was typed as Le (a-b-) phenotype and the FUT3 genotype was homozygote for non-functional le(59, 508) alleles. In conclusion, anti-Le(b) antibody can result in hemolytic transfusion reaction, FUT3 gene is homozygous for le(59, 508) allele resulting in Le (a-b-) phenotype.
