Differentially regulated genes not overlapping with ERCB data also reflected diabetes-associated changes, such as extracellular matrix (ANGPTL4, TNN, DPT, COL9A2) or gestational diabetes (LAT2, HP, CXCL10, CD86, CD68, REN, SLC2A3, VCAM1). The gene discussed is COL9A2; the disease is gestational diabetes.
