Abstract:

OBJECTIVE: To investigate the association of human leukocyte antigen(HLA) DRB1 gene polymorphisms with genetic susceptibility to breast cancer in Uyghur women. METHODS:Genomic DNA was isolated from peripheral blood of 196 patients with breast cancer and 230 healthy Uyghur women, HLA-DRB1 typing was performed by means of polymerase chain reaction-sequence-specific priming (PCR-SSP) and capillary electrophoresis sequencing (CE) method. RESULTS:The frequency of HLA-DRB1*01 genotype in breast cancer was significantly higher than in the control group (χ2=10.180, OR=4.550, P<0.05), while the frequency of HLA-DRB1*16 genotype was significantly lower than in the control group (χ2=4.792, OR=0.492, P<0.05). The frequencies of other HLA-DRB1 alleles did not show statistical significance between the two groups. CONCLUSION:Breast carcinogenesis in Uyghur women was closely associated with the allele polymorphisms of HLA-DRB1, which provides objective evidence for elucidating the molecular mechanism and clinical diagnosis for breast cancer.
