We searched the genes identified by both our study and [4] (namely, RUNX1, DLL1, EBF4, HOXA2, HOXA4, HHIP, NCAM1, NAV1, PRDM8, KDM2B) in the DisGeNET database, and found none of these genes has their highest association score (i.e. amount of evidence) with DS. Here, DLL1 is linked to Dravet syndrome.
