230437002: Severe myoclonic epilepsy in infancy (disorder)

SNOMED CT Concept\Clinical finding (finding)\...

\Head finding (finding)\Finding of brain\Seizure\Seizure disorder\A disease of the brain characterized by an enduring predisposition to generate epileptic seizures.\A type of epilepsy associated with developmental impairment where the developmental impairment is due to both the underlying etiology, independent of epileptic activity, and the superimposed epileptic encephalopathy. An epileptic encephalopathy is where the epileptic activity itself contributes to severe cognitive and behavioral impairments above and beyond what might be expected from the underlying pathology alone.\A genetic epilepsy of childhood with characteristics of drug-resistant seizures often induced by fever, presenting in previously healthy children, and which frequently leads to cognitive and motor impairment. Seizures can regress in adulthood but most patients have ongoing seizures that are refractory to medication. Around 85% of cases are due to a mutation or deletion in the SCN1A gene (2q24.3), encoding a voltage-gated sodium channel essential for the excitability of neurons. In families with a known SCN1A mutation, inheritance is autosomal dominant.
