初潮年龄和自然绝经年龄与乳腺癌和心血管疾病等大量发病率和死亡率的原因有关。研究表明,这两种特征可能部分受到遗传控制。我们对来自护士健康研究(NHS,N= 2,287)和女性基因组健康研究(WGHS,N= 15,151)的17,438名女性进行了这两种特征的两项全基因组关联研究的联合分析。对于初潮年龄,我们确定了10个相关的SNPs(P=1×10-7-3×10-13),聚集在6 q21(在基因LIN 28 B内或附近)和9q31.2(在基因间区域)。对于自然绝经年龄,我们确定了13个相关SNP(P=1×10-7-1×10-21),分别聚集在20p12.3(在基因MCM 8中)、19q13.42(在基因BRSK 1中或附近)、5q35.2(在基因RAP 80和HK 3中或附近)和6p24.2(在基因SYCP 2L中)。这些新发现的基因座可能会扩大对调节这两种性状的生物学途径的理解。
Age at menarche and age at natural menopause are associated with causes of substantial morbidity and mortality such as breast cancer and cardiovascular disease. Studies have suggested both traits might be partially under genetic control. We performed 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 10 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 RAP80 and HK3), and 6p24.2 (in the gene SYCP2L). These newly identified loci might expand understanding of the biological pathways regulating these two traits.
