Definition

IDDMSSD is a neurodevelopmental disorder characterized by impaired intellectual development, poor speech, postnatal macrocephaly, and seizures (Harms et al., 2018). [from OMIM]

Clinical features

From HPO
Gastroesophageal reflux
MedGen UID:
1368658
Concept ID:
C4317146

Microtia
MedGen UID:
57535
Concept ID:
C0152423
Congenital Abnormality
Underdevelopment of the external ear.
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.
Intellectual disability, severe
MedGen UID:
48638
Concept ID:
C0036857
Mental or Behavioral Dysfunction
Severe mental retardation is defined as an intelligence quotient (IQ) in the range of 20-34.
Unsteady gait
MedGen UID:
68544
Concept ID:
C0231686

Sign or Symptom
A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.
Delayed myelination

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.
