Presentation

The symptoms include:

• Skin lesions
  • Hypoplastic or aplastic skin defects
  • Pedunculated, hamartomatous or nodular skin appendages

  • Forebrain anomalies
    • Agenesis of the corpus callosum
    • Enlarged lateral ventricles
    • Interhemispheric cysts
    • Hydrocephalus
    • Polymicrogyria
    • Periventricular nodular heterotopia
  • Mid-hindbrain malformation
    • Giant dysplastic tectum
    • Absent cerebellar vermis

Genetics

While the disorder is not fully understood, it is suspected that the gene(s) responsible may lie on the X chromosome.

Diagnosis
