A meta-analysis of 39 studies, including 95,750 women diagnosed with GDM and duration of follow-up of between 6 weeks and 20 years postpartum, reported similar results to those of our cohort in terms of increased risk of dysglycaemia in women of non-white ethnicity, early diagnosis of GDM, and use of insulin therapy [25]. The gene discussed is INS; the disease is gestational diabetes.
