Abstract:

Objective To explore associations between MDM4rs4245739 gene polymorphism and breast cancer susceptibility. Methods The papers related to polymorphisms of MDM4rs4245739 and breast cancer susceptibility were searched in PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure and Wanfang electronic database. Odds ratios (ORs) and 95% confidence intervals (CIs) were adopted to assess the strength of associations. Publication bias was evaluated by Begg's funnel plot and Egger's linear regression test. Results A total of 6 studies involving 9 814 breast cancer patients and 45 202 healthy individuals were included in the present study. MDM4rs4245739 in the allelic (C vs A: OR=0.84, 95%CI: 0.67-1.05, P =0.118), dominant (AC+CC vs AA: O R=0.86, 95% CI: 0.67-1.11, P =0.245), recessive (AC+AA vs CC: OR=0.90, 95%CI: 0.61-1.32, P =0.585), heterozygous (AC vs AA: OR =0.88, 95%CI: 0.69-1.12, P=0.305), homozygous (CC vs AA: OR =0.90, 95% CI: 0.59-1.39, P=0.649) genetic models show no association with the susceptibility to breast cancer. Moreover, GEPIA data confirmed that the expression level of MDM4 was not associated with the tumor staging and prognosis of breast cancer. Conclusion Neither MDM4rs4245739 gene polymorphism nor MDM4 expression level is associated with the susceptibility and prognosis in breast cancer patients.
