Considering the important role of ANM in breast carcinogenesis, we hypothesized that TGFBR2 signals were involved in the formation of natural menopause.In a population-based study of 1844 Chinese women, we evaluated the effect of the genetic polymorphisms of TGFBR2 and miR-518 to determine if they are associated with ANM, premature ovarian failure (POF), and early menopause (EM) risk.No significant differences in the distribution of body mass index, education levels, smoking, drinking, and hypertension were detected between POF and EM cases and controls except for POF cases that were older (P = 0.015) than controls and more likely to have dyslipidemia (P = 0.002).
