A clusterof differentially expressed genes (DEG) whose expression level is increased inpatients with preeclampsia includes not only the known candidate genes thathave been identified in many other genome-wide studies (e.g.,LEP, BHLHB2, SIGLEC6,RDH13, BCL6), but also new genes(ANKRD37, SYDE1, CYBA,ITGB2, etc.), which can be considered as new biologicalmarkers of preeclampsia and are of further interest. The gene discussed is SYDE1; the disease is preeclampsia.
