Zhongguo shi yan xue ye xue za zhi 2022 JunTo investigate the molecular mechanism of one patient with abnormal serological phenotype in RhD and discuss the transfusion strategy. 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. 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. 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.
