In addition, a secondary analysis of the DALI study found that the duration of SB (especially in the 1st and 2nd trimesters) was negatively associated with the expression of placental FATP2 and FATP3 (37), which are involved in fatty acid protein transport and are linked to the pathogenesis of abnormal lipid metabolism in GDM (38). The gene discussed is SLC27A2; the disease is gestational diabetes.
