Brief summary: This maternal genome-wide meta-analysis of gestational duration (n=195 555) found 22 associated loci and an enrichment in genes expressed during labour. The related meta-analysis of preterm delivery (18 797 cases, 260 246 controls) revealed seven associated loci and large genetic similarities with gestational duration. Maternal alleles that increase gestational duration had a negative effect on birth weight.Preterm delivery is one...
