Peri/Postnatal Epigenetics Twin Study (PETS)
PETS follows a cohort of over 200 twin pairs and their mothers from Melbourne, Australia. The included twin pairs consisted of 42.1% monozygotic twins, and 57.9% dizygotic twins. Mothers who were attending multiple pregnancy clinics at three Melbourne hospitals were recruited into the study at 18 to 22 weeks gestation from 2008 to 2011, with data first collected from the twins at birth.
