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. This evidence concerns the gene BHLHE40 and preeclampsia.
