Various studies have shown that brain-derived neurotrophic factor (BDNF) increased neuronal excitability. We tested that BDNF might be involved in the etiology of febrile seizures (FSs). A total of 186 Taiwanese children were divided into two groups: (1) FSs (n = 104); (2) normal control subjects (n = 83). A single base pair polymorphism SNP6265 (Val66Met) at position 196 was analyzed. Our findings suggest that the BDNF polymorphisms were not candidate genetic markers.
