Developmental and epileptic encephalopathy, 86(EIEE86; DEE86)

MedGen UID:
1711964
Concept ID:
C5394462
Disease or Syndrome
Synonym: EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 86
 
Gene (location): DALRD3 (3p21.31)
 
Monarch Initiative: MONDO:0030054
OMIM®: 618910

Definition

Developmental and epileptic encephalopathy-86 (DEE86) is an X-linked neurologic syndrome characterized by severe and persistent seizures associated with EEG abnormalities beginning in the first few months of life, global developmental delay, severe motor deficits, dystonic movements, and dysmorphic facial features (Lentini et al., 2020). 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.
Gastrostomy tube feeding in infancy
MedGen UID:
892362
Concept ID:
C4023342
Finding
Feeding problem necessitating gastrostomy tube feeding.
Dystonic disorder
MedGen UID:
3940
Concept ID:
C0013421
Sign or Symptom
An abnormally increased muscular tone that causes fixed abnormal postures. There is a slow, intermittent twisting motion that leads to exaggerated turning and posture of the extremities and trunk.
Severe global developmental delay
MedGen UID:
332436
Concept ID:
C1837397
Finding
A severe delay in the achievement of motor or mental milestones in the domains of development of a child.
Absent speech
MedGen UID:
340737
Concept ID:
C1854882
Finding
Complete lack of development of speech and language abilities.
CNS hypomyelination
MedGen UID:
892446
Concept ID:
C4025616
Finding
Reduced amount of myelin in the central nervous system resulting from defective myelinogenesis.
Myoclonic seizure
MedGen UID:
1385980
Concept ID:
C4317123
Sign or Symptom
A myoclonic seizure is a type of motor seizure characterized by sudden, brief (<100 ms) involuntary single or multiple contraction of muscles or muscle groups of variable topography (axial, proximal limb, distal). Myoclonus is less regularly repetitive and less sustained than is clonus.
Generalized amyotrophy
MedGen UID:
234650
Concept ID:
C1389113
Disease or Syndrome
Generalized (diffuse, unlocalized) amyotrophy (muscle atrophy) affecting multiple muscles.
Generalized hypotonia
MedGen UID:
346841
Concept ID:
C1858120
Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Microcephaly
MedGen UID:
1644158
Concept ID:
C4551563
Finding
Head circumference below 2 standard deviations below the mean for age and gender.
Oligohydramnios
MedGen UID:
86974
Concept ID:
C0079924
Pathologic Function
Diminished amniotic fluid volume in pregnancy.
