ABSTRACT
【Objective】 To genetically analyze the Del sample from a blood donor in Jiangyin and make clear the molecular basis of the serological phenotype. 【Methods】 The EDTA anticoagulant blood were collected: buffy coat were used for nucleic acid extract and cDNA analysis; red blood cells for serological test. Tube method and microcolumn gel were used for serological test. Genotyping kit were used for exon analysis. Gene mutation was analyzed using the sequence analyzer. 【Results】 Serological analysis demonstrated the sample′s RhD phenotype was Del. The phenotype of RhCE was CCEe. Real-time fluorescence quota PCR result demonstrated the existence of all exones. Weak D15 and RHD* DEL1 [RHD(1227G>A)], which had a high frequency of occurrence in China, were excluded according to real-time fluorescence quota PCR result. Sequence analyzing result verified RHD(28C>T) SNP mutation in cDNA. The genotype of this sample was RHD*01 W. 61[RHD(28C>T)]. 【Conclusion】 A weak D61 was found among blood donors in our city, Jiangyin.
