OBJECTIVETo study the distribution of HLA-DRB1 allele polymorphism in Uyghur women with family history of cervical cancer, and provide theoretical evidence for detection and follow-up of high risk persons for cervical cancer by detection of HLA-DRB1 allele polymorphism.

METHODSThe HLA-DRB1 13 alleles were detected in 1000 Uyghur women, all from Hotan Moyu county Karsay village by using polymerase chain reaction sequence-specific oligonucleotide (PCR-SSO) assay.

RESULTSThe frequencies of HLA-DRB1*15 in women with family history of cervical cancer (17.3%), mother (18.0%) and other relatives except mother (17.0%) who had suffered from cervical cancer were significantly higher than that in the control group (9.7%, all P < 0.05). The frequencies of HLA-DRB1*04 in women with family history (16.8%) and other relatives except mother (20.7%) were significantly higher than that in the control group (12.7%, all P < 0.05). The frequencies of HLA-DRB1*03 in women with family history (2.6%) and other relatives except mother (1.1%) were significantly lower than that in the control group (6.3%, all P < 0.01). The frequencies of HLA-DRB1*12 in women with family history of cervical cancer (2.3%) and mother suffered from cervical cancer (1.5%) were significantly lower than that in the control group (5.7%, all P < 0.05). The frequencies of HLA-DRB1*14 in women with family history of cervical cancer (5.4%) and mother who suffered from cervical cancer (3.0%) were significantly lower than that in the control group (8.4%, all P < 0.05).

CONCLUSIONSThere are similarity and difference in distribution of HLA-DRB1 allele polymorphisms between the Uyghur women with family history of cervical cancer from Hotan Moyu county and those from southern Xingjiang area. In general, the distribution of HLA-DRB1 allele polymorphism in women with family history of cervical cancer is similar to that reported in abroad. The results of this study support the role of susceptible and protective HLA gene detection in screening high risk persons for this cancer among Uyghur women from cervical cancer high risk areas in Xinjiang.
