[Identification of Phenotype and Genotype in One Case with Weak D blood group].

OBJECTIVE: To investigate the phenotype and genotype of the weak D blood group in one case of Chinese Han people. METHODS: Phenotype of blood sample was identified with serologic tests; PCR-SBT was applied for the analysis of genotype and RhD zygosity. RESULTS: Both saline and gel card tests demonstrated this case to be dCcee, which was contrary to glass bead card result. Some of the RBC D epitopes were negative.c.1022T>A allele was identified with PCR-SBT and the zygosity analysis showed this case to be D/d. CONCLUSION: RHD*1022 A is more suitable to be categorized as weak partial D other than weak D in a Chinese Han people.
