Introduction Genetic factors contribute to weight gain, but how these effects change over adulthood is still unknown. We studied the impact of genetics on BMI change from young adulthood to old age and its relationship with BMI in early you…
PURPOSE: Natural dizygotic twinning (DZT) results from hyper-ovulation and is an indicator of female fertility. However, some traits linked to DZ twinning are also associated with infertility. We examined the relationship between DZT and fe…
Study questionWhich genetic factors regulate female propensity for giving birth to spontaneous dizygotic (DZ) twins?Summary answerWe identified four new loci, GNRH1, FSHR, ZFPM1, and IPO8, in addition to previously identified loci, FSHB and…
Natural dizygotic twinning (DZT) results from hyper-ovulation and is considered an indicator of female fertility. DZT has low polygenicity, with only 0.20% of SNPs estimated to have a nonzero effect. A polygenic score (PGS) for DZT explains…
