title: [Association between genetic variants in p53 binding sites and risks of breast cancer in Chinese population].
abstract: OBJECTIVE
  To investigate the association between breast tissue specified variants in p53 binding sites and the risk of BC in Chinese women.
  
  
  METHODS
  ChIP-seq database on p53 binding sites in MCF-7 cell lines was extracted to identify the possible variants in p53 target genes. A hospital-based case-control study was then performed to investigate the association between variants in p53 binding sites and the risk of BC in a Chinese women population.
  
  
  RESULTS
  Three variants were identified from the bioinformatics analysis. A total of 1 274 BC cases and 1 255 frequency-matched cancer-free controls were included in this case-control study. The average age was comparable between the case and the control groups, with the P value as 0.318. Meanwhile, distributions on menopausal status, smoking and alcohol intake between cases and controls were similar with the P values as 0.539, 0.258 and 0.131, respectively. The genotype distribution of rs1295925 was significantly different between the case and the control groups. Individuals that carrying rs1295925-CT and rs1295925-TT genotypes were significantly associated with an increased BC risk when compared with rs1295925-CC genotype after adjustment of age, menopausal status, smoking and alcohol intake (OR=1.32, 95%CI: 1.07-1.62 and OR=1.41, 95%CI: 1.13-1.78, respectively). Positive associations were also observed under the allelic, dominant and additive models.
  
  
  CONCLUSIONS
  rs1295925 which located in VMP1 gene was associated with increased BC risk in the Chinese women population.
