Abstract:
Objective:To investigate the correlation of single nucleotide polymorphisms (SNPs) in the PRRC2A gene with the susceptibility to sporadic breast cancer among Han women in Jiangsu Province, China. Methods:Using the genotyping technique of matrix-assisted laser desorption-ionization time-of-flight mass spectrometry, we analyzed the polymorphisms of an SNP (chr6_31697494) in gene PRRC2A in 214 breast cancer patients and 212 healthy controls admitted to the Huaian Maternal and Child Health Care Hospital. The genotype frequencies were analyzed using a Chi-square test between the case and control groups. Unconditional lo-gistic regression analysis for calculating the odds ratio (OR) and 95%confidence interval (95%CI) was conducted by analyzing the cor-relation between the susceptibility to breast cancer and genotypes. Additional analysis was then performed based on the immunohisto-chemical results of the estrogen receptor (ER) and progesterone receptor (PR). Results:The genotype frequencies for chr6_31697494 between the case and control groups were not significantly different (P>0.05). Further analysis indicated that the genotype frequencies of the site were significantly different in the ER (+/-) groups or the PR (+/-) groups (P<0.05). Heterozygous genotype (chr6_31697494, CT) was related to the breast cancers with ER (+) and PR (+) (OR=0.40, 95%CI:0.33-0.47;OR=0.49, 95%CI:0.43-0.57, respectively). Conclusion:No significant difference was found between the polymorphism of chr6_31697494 in the PRRC2A gene and the suscepti-bility to breast cancer among Han women in Jiangsu Province. The heterozygous genotypes were associated with breast cancer tissues with ER (+) and PR (+).
