Objective:
To investigate the frequencies distribution of human leukocyte antigen (HLA)-B27 subtypes in unrelated healthy Chinese.
Method:
Polymerase chain reaction sequence-based typing (PCRSBT) was used to determine HLA high-resolution genotypes of 825 unrelated healthy Chinese.
Results:
A total of 25 HLA-B27-positive individuals and 8 HLA-B27 subtypes were detected. These subtypes and their corresponding frequencies were B * 2704 (30.77%) , B * 2705 (23.08%), B * 2707 (19.23%), B * 2711 (7.69%), B * 2712 (7.69%), B * 2701 (3.85%), B * 2713 (3.85%) and B * 2721 (3.85%).
Conclusion:
The data obtained through PCR-SBT method may serve as important reference for the research of relationship between HLA-B27 subtypes and some diseases such as ankylosing spondylitis.
