Epilepsy, familial adult myoclonic, 5(EPEO5)

MedGen UID:
815704

C3809374
Disease or Syndrome
Synonyms: CORTICAL MYOCLONIC TREMOR WITH EPILEPSY, FAMILIAL, 5; EPEO5
 
Gene (location): CNTN2 (1q32.1)
 
Monarch Initiative: MONDO:0014167

Definition

Early-onset epilepsy-5 with or without developmental delay (EPEO5) is an autosomal recessive neurologic disorder characterized by the onset of various types of seizures late in the first decade or during adolescence. Focal seizures are common. Most affected individuals have developmental delay, variable impaired intellectual development, and/or behavioral and neuropsychiatric abnormalities (Stogmann et al., 2013; Abdulkareem et al., 2023). For a discussion of genetic heterogeneity of EPEO, see 617290. [from OMIM]

Clinical features

From HPO
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.
Tremor
MedGen UID:
21635
Concept ID:
C0040822
Sign or Symptom
An unintentional, oscillating to-and-fro muscle movement about a joint axis.
Focal impaired awareness seizure
MedGen UID:
543022
Concept ID:
C0270834
Disease or Syndrome
Focal impaired awareness seizure (or focal seizure with impaired or lost awareness) is a type of focal-onset seizure characterized by some degree (which may be partial) of impairment of the person's awareness of themselves or their surroundings at any point during the seizure.
Focal sensory seizure with visual features
MedGen UID:
75815
Concept ID:
C0278188
Disease or Syndrome
A seizure characterized by elementary visual hallucinations such as flashing or flickering lights/colors, or other shapes, simple patterns, scotomata, or amaurosis as its first clinical manifestation.
Bilateral tonic-clonic seizure
MedGen UID:
141670
Concept ID:
C0494475
Sign or Symptom
A bilateral tonic-clonic seizure is a seizure defined by a tonic (bilateral increased tone, lasting seconds to minutes) and then a clonic (bilateral sustained rhythmic jerking) phase.
Hippocampal sclerosis
MedGen UID:
1778719
Concept ID:
C1504404
Disease or Syndrome
Hippocampal sclerosis is a neuropathologic finding characterized by neuronal loss and gliosis in the CA-1 and subiculum of the hippocampus.
Interictal epileptiform activity
MedGen UID:
869073
Concept ID:
C4023491
Finding
Epileptiform activity refers to distinctive EEG waves or complexes distinguished from background activity found in in a proportion of human subjects with epilepsy, but which can also be found in subjects without seizures. Interictal epileptiform activity refers to such activity that occurs in the absence of a clinical or subclinical seizure.
