Benign familial infantile seizure (BFIS) is an autosomal dominant disease characterized by focal seizures, occurring mostly in clusters, and usually first seen between 4 and 8 months of life. Psychomotor development is normal, and seizures usually resolve within the first year of life. PRRT2 has been identified as the major gene found to be mutated in 80 to 90% of cases. Recently, mutations in the genes coding for the voltage-gated sodium channel subunits have been reported.
