Penetrance For kcnq2-bfne, penetrance is incomplete, with about 77%-85% of individuals heterozygous for a pathogenic variant in kcnq2 showing neonatal or early-infantile seizures [plouin & neubauer 2012, grinton et al 2015]...

Summaries for Kcnq2-Related Disorders

NIH Rare Diseases : ⁵³ KCNQ2-related disorders are a group of epileptic diseases that start during the first 4 weeks of a child's life (neonatal period). The groups is made up of various different diseases whose signs and symptoms vary. The conditions range from the less severe form KCNQ2-related benign familial neonatal epilepsy (KCNQ2-BFNE) to the more severe form KCNQ2-related epileptic encephalopathy (KCNQ2-NEE). KCNQ2-BFNE is characterized by seizures that start in otherwise healthy infants around day 3 of life and usually go away within 1 to 4 months. KCNQ2-NEE is characterized by epilepsy and profound intellectual disability and seizures that begin in the first weeks of life and typically show little response to treatment. They usually go away in a few months to a few years but can return later in childhood. These disorders are caused by mutations in the KCNQ2 gene. Inheritance is autosomal dominant. Treatment is with antiseizure medications.

MalaCards based summary : Kcnq2-Related Disorders is related to early infantile epileptic encephalopathy. An important gene associated with Kcnq2-Related Disorders is KCNQ2 (Potassium Voltage-Gated Channel Subfamily Q Member 2).
