Neurodevelopmental disorder with dysmorphic facies and variable seizures(NEDDFAS)

MedGen UID:
1784197
Concept ID:
C5543268
Disease or Syndrome
Synonym: NEDDFAS
 
Gene (location): EMC10 (19q13.33)
 
Monarch Initiative: MONDO:0031011
OMIM®: 619264

Definition

Neurodevelopmental disorder with dysmorphic facies and variable seizures (NEDDFAS) is an autosomal recessive disorder characterized by global developmental delay apparent in early childhood. Patients have mildly impaired intellectual development, often with speech delay or behavioral abnormalities. Some may have seizures. Most have nonspecific dysmorphic facial features. Additional findings may include brain imaging abnormalities, mild skeletal defects, and renal abnormalities, although the renal anomalies may be unrelated (summary by Shao et al., 2021). [from OMIM]

Clinical features

From HPO
Anxiety
MedGen UID:
1613
Concept ID:
C0003467
Finding
Intense feelings of nervousness, tension, or panic often arise in response to interpersonal stresses. There is worry about the negative effects of past unpleasant experiences and future negative possibilities. Individuals may feel fearful, apprehensive, or threatened by uncertainty, and they may also have fears of falling apart or losing control.
Febrile seizure (within the age range of 3 months to 6 years)
MedGen UID:
3232
Concept ID:
C0009952
Disease or Syndrome
A febrile seizure is any type of seizure (most often a generalized tonic-clonic seizure) occurring with fever (at least 38 degrees Celsius) but in the absence of central nervous system infection, severe metabolic disturbance or other alternative precipitant in children between the ages of 3 months and 6 years.
Dysarthria
MedGen UID:
8510
Concept ID:
C0013362
Mental or Behavioral Dysfunction
Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.
Intellectual disability, mild
MedGen UID:
10044
Concept ID:
C0026106
Mental or Behavioral Dysfunction
Mild intellectual disability is defined as an intelligence quotient (IQ) in the range of 50-69.
Diminished ability to concentrate
MedGen UID:
65900
Concept ID:
C0235198
Finding
Being unable to focus one's attention or mental effort on a particular object or activity.
Delayed speech and language development
MedGen UID:
105318
Concept ID:
C0454644
Finding
A degree of language development that is significantly below the norm for a child of a specified age.
Global developmental delay
MedGen UID:
107838
Concept ID:
C0557874
Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Tics
MedGen UID:
853666
Concept ID:
C2169806
Sign or Symptom
Repeated, individually recognizable, intermittent movements or movement fragments that are almost always briefly suppressible and are usually associated with awareness of an urge to perform the movement.
Frontal bossing
MedGen UID:
67453
Concept ID:
C0221354
Congenital Abnormality
Bilateral bulging of the lateral frontal bone prominences with relative sparing of the midline.
Plagiocephaly
MedGen UID:
1825944
Concept ID:
C2081594
Finding
Asymmetric head shape, which is usually a combination of unilateral occipital flattening with ipsilateral frontal prominence, leading to rhomboid cranial shape.
Dental crowding
MedGen UID:
11850
Concept ID:
C0040433
Finding
Changes in alignment of teeth in the dental arch
Triangular face
MedGen UID:
324383
Concept ID:
C1835884
Finding
Facial contour, as viewed from the front, triangular in shape, with breadth at the temples and tapering to a narrow chin.
Broad forehead
MedGen UID:
338610
Concept ID:
C1849089
Finding
Width of the forehead or distance between the frontotemporales is more than two standard deviations above the mean (objective); or apparently increased distance between the two sides of the forehead.
Hirsutism
MedGen UID:
42461
Concept ID:
C0019572
Disease or Syndrome
Abnormally increased hair growth referring to a male pattern of body hair (androgenic hair).
Synophrys
MedGen UID:
98132
Concept ID:
C0431447
Congenital Abnormality
Meeting of the medial eyebrows in the midline.
Fetal distress
MedGen UID:
5164
Concept ID:
C0015930
Pathologic Function
An intrauterine state characterized by suboptimal values in the fetal heart rate, oxygenation of fetal blood, or other parameters indicative of compromise of the fetus. Signs of fetal distress include repetitive variable decelerations, fetal tachycardia or bradycardia, late decelerations, or low biophysical profile.
Nystagmus
MedGen UID:
45166
Concept ID:
C0028738
Disease or Syndrome
Rhythmic, involuntary oscillations of one or both eyes related to abnormality in fixation, conjugate gaze, or vestibular mechanisms.
