MENTAL RETARDATION, AUTOSOMAL DOMINANT 6, WITH OR WITHOUT SEIZURES; MRD6

Description

MRD6 is an autosomal dominant neurodevelopmental disorder characterized by delayed psychomotor development and intellectual disability of variable severity. Additional features may include seizures, hypotonia, abnormal movements, such as dystonia, and autistic features. Some patients may have structural malformations of cortical development on brain imaging. The phenotype is highly variable and reflects a spectrum of neurodevelopmental abnormalities that range from mild intellectual disability without seizures to an encephalopathy (summary by Platzer et al., 2017).

Most common symptoms of MENTAL RETARDATION, AUTOSOMAL DOMINANT 6, WITH OR WITHOUT SEIZURES; MRD6

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Microcephaly

WEST SYNDROME

Alternate names

WEST SYNDROME Is also known as intellectual disability-hypsarrhythmia syndrome, infantile spasm syndrome, x-linked 1, xmesid, west syndrome, x-linked, ohtahara syndrome, x-linked, infantile spasms, infantile epileptic-dyskinetic encephalopathy, issx1

Description

West syndrome (or infantile spasms) is characterised by the association of clusters of axial spasms, psychomotor retardation and an hypsarrhythmic interictal EEG pattern. It is the most frequent type of epileptic encephalopathy. It may occur in otherwise healthy infants and in those with abnormal cognitive development.

Most common symptoms of WEST SYNDROME

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Microcephaly
  • Ataxia

AUTOSOMAL DOMINANT NON-SYNDROMIC INTELLECTUAL DISABILITY

EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 27; EIEE27

Description

Early infantile epileptic encephalopathy-27 is an autosomal dominant neurodevelopmental disorder characterized by delayed psychomotor development and intellectual disability of variable severity associated with early-onset seizures. Additional features may include hypotonia, abnormal movements, such as dystonia, and autistic features. Some patients may have structural malformations of cortical development on brain imaging. The phenotype is highly variable and reflects a spectrum of neurodevelopmental abnormalities that range from mild intellectual disability without seizures to an encephalopathy (summary by Platzer et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of EIEE, see EIEE1 (OMIM ).

Most common symptoms of EPILEPTIC ENCEPHALOPATHY, EARLY INFANTILE, 27; EIEE27

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Microcephaly
