Developmental and epileptic encephalopathy, 61(EIEE61; DEE61)

MedGen UID:
1639392
•Concept ID:
C4693688
•
Disease or Syndrome
Synonym: Early infantile epileptic encephalopathy 61
 
Gene (location): ADAM22 (7q21.12)
 
Monarch Initiative: MONDO:0033370
OMIM®: 617933

Definition

Developmental and epileptic encephalopathy-61 (DEE61) is an autosomal recessive neurologic disorder characterized by the onset of refractory seizures in the first months or years of life. There is profound global developmental delay with intellectual disability, inability to walk, poor voluntary movements, spasticity, microcephaly, cerebral atrophy, and dysmorphic facial features (summary by Muona et al., 2016). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. [from OMIM]

Spasticity
MedGen UID:
7753
•Concept ID:

Seizure
MedGen UID:
20693

Epileptic encephalopathy
MedGen UID:
452596
•Concept ID:
C0543888
•
Disease or Syndrome
A condition in which epileptiform abnormalities are believed to contribute to the progressive disturbance in cerebral function. Epileptic encephalaopathy is characterized by (1) electrographic EEG paroxysmal activity that is often aggressive, (2) seizures that are usually multiform and intractable, (3) cognitive, behavioral and neurological deficits that may be relentless, and (4) sometimes early death.
