(A) Genome-wide significant loci associated with menarche, menopause, polycystic ovary syndrome, FSH and LH levels, and menstrual cycle length; and genes associated with monogenic forms of POI. (B) Genetic correlations between phenotypes reflecting ovarian physiology and overall health status. Data are from published studies [9,10,19] that report genetic correlations based on observed pleiotropy between loci or LD score regression analysis. Abbreviations: AMH, anti-Müllerian hormone; FSH, follicle-stimulating hormone; LD, linkage disequilibrium; LH, luteinizing hormone; PAI-1, plasminogen activator inhibitor type 1; PCOS, polycystic ovary syndrome; POI, premature ovarian insufficiency.
