ABSTRACT
OBJECTIVE@#To investigate the molecular mechanism of one patient with abnormal serological phenotype in RhD and discuss the transfusion strategy.@*METHODS@#The RhD variant sample was screened from a patient with IgM type anti-D antibody and further determined by three different sources of anti-D antibodies. Ten exons and the adjacent introns of the RHD gene were amplified, purified and sequenced. RhCE phenotypes and RHCE genotypes were detected.@*RESULTS@#The patient with Rh variant showed abnormal results of serological tests. The RHD gene sequence analysis showed that the RHD*01W.01 with a variation (c.809T>G, p.Val270Gly) in exon 6 of the RHD gene was found in the patient. The RhCE phenotype was CcEe. The genotyping results of RHCE were consistent with the serological typing results.@*CONCLUSION@#The Rh variant of the patient is RHD*01W.01, these findings indicate that RhD variants should be analyzed by molecular assays for the sake of safe transfusion.
