Genome-wide association studies identify loci associated with age at menarche and age at natural menopause.

ABSTRACT: Age at menarche and age at natural menopause are associated with causes of substantial morbidity and mortality such as breast cancer and cardiovascular disease. We conducted a joint analysis of two genome-wide association studies of these two traits in a total of 17,438 women from the Nurses' Health Study (NHS, N = 2,287) and the Women's Genome Health Study (WGHS, N = 15,151). For age at menarche, we identified ten associated SNPs (P = 1 × 10(-7)-3 × 10(-13)) clustered at 6q21 (in or near the gene LIN28B) and 9q31.2 (in an intergenic region). For age at natural menopause, we identified 13 associated SNPs (P = 1 × 10(-7)-1 × 10(-21)) clustered at 20p12.3 (in the gene MCM8), 19q13.42 (in or near the gene BRSK1), 5q35.2 (in or near genes UIMC1 and HK3) and 6p24.2 (in the gene SYCP2L).
