Benign familial neonatal and infantile epilepsies, including:
Benign familial neonatal epilepsy (BFNE);
Benign familial neonatal infantile epilepsy (BFNIE);
Benign familial infantile epilepsy (BFIE)
Benign familial neonatal epilepsy (BFNE), benign familial neonatal infantile epilepsy (BFNIE), and benign familial infantile epilepsy (BFIE) are three benign epilepsy syndromes with autosomal dominant inheritance distinguished by ascending average ages of seizure onset (mean age at onset of 2-3 days; 11 weeks; and 6 months, respectively). They are a group of genetic (idiopathic) epilepsies which have a primary genetic background, usually no structural brain abnormalities and most of them have a benign course without additional neurological symptoms. For BFNE and BFNIE, genetic defects have already been identified. Whereas BFNE are caused by loss-of-function mutations in the two genes KCNQ2 and KCNQ3 encoding the voltage-gated K+ channels Kv7.2 and Kv7.3, mutations in the gene SCN2A encoding the voltage-gated Na+ channel Nav1.2 have been detected in BFNIE. There are as yet no known genes identified for BFIE.
