Disease characteristics

Excerpted from the GeneReview: SLC12A5-Related Epilepsy of Infancy with Migrating Focal Seizures
SLC12A5-related epilepsy of infancy with migrating focal seizures (SLC12A5-EIMFS), reported to date in nine children, is characterized by onset of seizures before age six months and either developmental delay or developmental regression with seizure onset. Of these nine children, six had severe developmental delay with no progress of abilities and three made notable neurodevelopmental progress. Eight had postnatal microcephaly and hypotonia. In most children epilepsy begins as focal motor seizures (typically involving head and eye deviation) that become multifocal and intractable to conventional anti-seizure medication (ASM). [from GeneReviews]

Additional description

From OMIM
Developmental and epileptic encephalopathy-34 (DEE34) is an autosomal recessive severe neurologic disorder characterized by onset of refractory migrating focal seizures in the first year of life after normal early development. Affected children show developmental regression and are severely impaired globally (summary by Stodberg et al., 2015). For a discussion of genetic heterogeneity of DEE, see 308350.  http://www.omim.org/entry/616645

Clinical features

From HPO
Seizure
MedGen UID:
20693
•Concept ID:
C0036572
•
Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterized by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
See: Feature record | Search on this feature
Status epilepticus
MedGen UID:
11586
•Concept ID:
C0038220
•
Disease or Syndrome
Status epilepticus is a type of prolonged seizure resulting either from the failure of the mechanisms responsible for seizure termination or from the initiation of mechanisms which lead to abnormally prolonged seizures (after time point t1). It is a condition that can have long-term consequences (after time point t2), including neuronal death, neuronal injury, and alteration of neuronal networks, depending on the type and duration of seizures.
