Developmental and epileptic encephalopathy, 40(DEE40)

MedGen UID:
934704
Concept ID:
C4310737
Disease or Syndrome
Synonyms: DEE40; Epileptic encephalopathy, early infantile, 40
 
Gene (location): GUF1 (4p12)
 
Monarch Initiative: MONDO:0014895
OMIM®: 617065

Definition

Developmental and epileptic encephalopathy-40 (DEE40) is an autosomal recessive neurologic disorder characterized by the onset of refractory infantile spasms within the first 6 months of life. Affected infants may have normal or mildly delayed development before the onset of seizures, but thereafter show developmental stagnation and severe neurologic impairment. EEG typically shows hypsarrhythmia, consistent with a clinical diagnosis of West syndrome. Additional features include poor feeding, axial hypotonia with peripheral spasticity, limited eye contact, profoundly impaired intellectual development with absent language, and poor fine motor skills (summary by Alfaiz et al., 2016). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. [from OMIM]

Clinical features

From HPO
Sudden unexpected death in epilepsy
MedGen UID:
930396
Concept ID:
C4304727
Finding
Sudden unexpected death in epilepsy (SUDEP) is a sudden, unexpected, witnessed or unwitnessed, non-traumatic and non-drowning death, occurring in benign circumstances, in an individual with epilepsy, with or without evidence for a seizure and excluding documented status epilepticus, in which postmortem examination has not revealed a cause of death.
Fetal growth restriction
MedGen UID:
4693
Concept ID:
C0015934
Pathologic Function
An abnormal restriction of fetal growth with fetal weight below the tenth percentile for gestational age.
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.
Feeding difficulties
MedGen UID:
65429
Concept ID:
C0232466
Finding
Impaired ability to eat related to problems gathering food and getting ready to suck, chew, or swallow it.
Lethargy
MedGen UID:
7310
Concept ID:
C0023380
Sign or Symptom
A state of disinterest, listlessness, and indifference, resulting in difficulty performing simple tasks or concentrating.
Spasticity
MedGen UID:
7753
Concept ID:
C0026838
Sign or Symptom
A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with increased muscle tone, exaggerated (hyperexcitable) tendon reflexes.
Myoclonus
MedGen UID:
10234
Concept ID:
C0027066
Finding
Very brief, involuntary random muscular contractions occurring at rest, in response to sensory stimuli, or accompanying voluntary movements.
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.
Choreoathetosis
MedGen UID:
39313
Concept ID:
C0085583
Disease or Syndrome
Involuntary movements characterized by both athetosis (inability to sustain muscles in a fixed position) and chorea (widespread jerky arrhythmic movements).
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.
Spastic tetraparesis
MedGen UID:
658719
Concept ID:
C0575059
Disease or Syndrome
Spastic weakness affecting all four limbs.
Hypsarrhythmia
MedGen UID:
195766
Concept ID:
C0684276
Finding
Hypsarrhythmia is abnormal interictal high amplitude waves and a background of irregular spikes. There is continuous (during wakefulness), high-amplitude (>200 Hz), generalized polymorphic slowing with no organized background and multifocal spikes demonstrated by electroencephalography (EEG).
Reduced eye contact
MedGen UID:
303190
Concept ID:
C1445953
Finding
A reduced frequency or duration of eye contact.
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.
Profound global developmental delay
MedGen UID:
766364
Concept ID:
C3553450
Disease or Syndrome
A profound delay in the achievement of motor or mental milestones in the domains of development of a child.
Cerebral cortical atrophy
MedGen UID:
1646740
Concept ID:
C4551583
Disease or Syndrome
Atrophy of the cortex of the cerebrum.
Hypotonia
MedGen UID:
10133
Concept ID:
C0026827
Finding
Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.
Axial hypotonia
MedGen UID:
342959
Concept ID:
C1853743
Finding
Muscular hypotonia (abnormally low muscle tone) affecting the musculature of the trunk.
Hyaline membranes
MedGen UID:
569214
Concept ID:
C0333563
Body Substance
Hyaline membranes are homogeneous eosinophilic material composed of cellular debris, plasma proteins, and surfactant plastered against alveolar ducts and alveolar walls. The hyaline membranes are deposited along the walls of the alveoli, where gas exchange typically occurs, thereby making gas exchange difficult.
