Developmental and epileptic encephalopathy 96(DEE96)

MedGen UID:
1780167
Concept ID:
C5543446
Disease or Syndrome
Synonyms: DEE96; DEVELOPMENTAL AND EPILEPTIC ENCEPHALOPATHY 96
 
Gene (location): NSF (17q21.31)
 
Monarch Initiative: MONDO:0023659
OMIM®: 619340

Definition

Developmental and epileptic encephalopathy-96 (DEE96) is characterized by onset of seizures in the first days or weeks of life. Affected infants have tonic or myoclonic seizures associated with burst-suppression pattern on EEG. They also have hypotonia with respiratory insufficiency that may result in premature death. Those that survive have profound developmental delay and persistent seizures (summary by Suzuki et al., 2019). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. [from OMIM]

Clinical features

From HPO
Small for gestational age
MedGen UID:
65920
Concept ID:
C0235991
Finding
Smaller than normal size according to sex and gestational age related norms, defined as a weight below the 10th percentile for the gestational age.
Tonic seizure
MedGen UID:
82855
Concept ID:
C0270844
Disease or Syndrome
A tonic seizure is a type of motor seizure characterized by unilateral or bilateral limb stiffening or elevation, often with neck stiffening.
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.
Epileptic spasm
MedGen UID:
315948
Concept ID:
C1527366
Disease or Syndrome
A sudden flexion, extension, or mixed extension-flexion of predominantly proximal and truncal muscles that is usually more sustained than a myoclonic movement but not as sustained as a tonic seizure. Limited forms may occur
EEG with burst suppression
MedGen UID:
369943
Concept ID:
C1969156
Finding
The burst suppression pattern in electroencephalography refers to a characteristic periodic pattern of low voltage (<10 microvolts) suppressed background and a relatively shorter pattern of higher amplitude slow, sharp, and spiking complexes.
Intellectual disability, profound
MedGen UID:
892508
Concept ID:
C3161330
Mental or Behavioral Dysfunction
Profound mental retardation is defined as an intelligence quotient (IQ) below 20.
Primary microcephaly
MedGen UID:
383046
Concept ID:
C2677180
Finding
Head circumference below 2 standard deviations below the mean for age and gender at birth.
Neonatal respiratory distress
MedGen UID:
924182
Concept ID:
C4281993
Finding
Respiratory difficulty as newborn.
Hydrops fetalis
MedGen UID:
6947
Concept ID:
C0020305
Disease or Syndrome
The abnormal accumulation of fluid in two or more fetal compartments, including ascites, pleural effusion, pericardial effusion, and skin edema.
