Thirty new loci for age at menarche identified by a meta-analysis of genome-wide association studies

To identify loci for age at menarche, we performed a meta-analysis of 32 genome-wide association studies in 87,802 women of European descent, with replication in up to 14,731 women. In addition to the known loci at LIN28B (P = 5.4 × 10 -60) and 9q31.2 (P = 2.2 × 10 -33), we identified 30 new menarche loci (all P < 5 × 10 -8) and found suggestive evidence for a further 10 loci (P < 1.9 × 10 -6). The new loci included four previously associate
