Profiling of transcriptome showed that expression of OSBPL5 (log2TPM) in the placenta of GDM patient was 2.4-fold of that in the control group (GDM 4.034 vs. control 2.767), but the difference was small in umbilical cord blood (GDM 0.757 vs. control 0.863). Here, OSBPL5 is linked to gestational diabetes.
