As a model for haploinsufficiency in vitro knock down of RBFOX1 in primary human neural stem cells resulted in an altered expression and splicing of several epilepsy candidate genes (FLNA, SLC1A3, DCX, GABRB3, GAD2, KCNQ2, SLC12A5, SV2B, SYN1) [19]. This evidence concerns the gene KCNQ2 and epilepsy.
