  • Title: [Comparative studies of serological typing and HLA-A, B antigen genotyping with PCR using sequence-specific primers].
    Author: Wu DL, Ling HX, Tang H.
    Journal: Di Yi Jun Yi Da Xue Xue Bao; 2004 Nov; 24(11):1267-70. PubMed ID: 15567775.
    Abstract:
    OBJECTIVE: To evaluate the accuracy of PCR with sequence-specific primers (PCR-SSP) for HLA-I genotyping and analyze the causes of the errors occurring in the genotyping. METHODS: DNA samples and were obtained from 34 clinical patients, and serological typing with monoclonal antibody (mAb) and HLA-A and, B antigen genotyping with PCR-SSP were performed. RESULTS: HLA-A and, B alleles were successfully typed in 34 clinical samples by mAb and PCR-SSP. No false positive or false negative results were found, and the erroneous and missed diagnosis rates were obviously higher in serological detection, being 23.5% for HLA-A and 26.5% for HLA-B. Error or confusion was more likely to occur in the antigens of A2 and A68, A32 and A33, B5, B60 and B61. CONCLUSIONS: DNA typing for HLA-I class (A, B antigens) by PCR-SSP has high resolution, high specificity, and good reproducibility, which is more suitable for clinical application than serological typing. PCR-SSP may accurately detect the alleles that are easily missed or mistaken in serological typing.
