Our results partially correspond to the results of previous studies showing decreased soma size of dorsal root ganglion neurons in Ret-floxed;Wnt1-Cre mice (27) and impaired development of GCs as well as PCs in DS model mice (Ts65Dn) (20) and staggerer (sg/sg) mice (28, 29). The gene discussed is RET; the disease is Dravet syndrome.
