Living with Cerebrooculonasal syndrome

A very rare condition present from birth with absent eyeballs, nose and brain differences, and developmental delay.

Understanding Cerebrooculonasal syndrome

Cerebrooculonasal syndrome is a very rare condition with several differences in the brain, eyes, and nose that has been reported in about 10 people.

Features include absent eyeballs in both eyes (anophthalmia), differences in the nostrils, brain differences, and developmental delay. People may also have a short, broad head and other facial differences, extra fingers, and underdeveloped genitals. It begins during pregnancy or at birth.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Absent eyeballs (anophthalmia)
  • Blindness
  • Differences in the nostrils
  • Differences in the brain and nervous system
  • Broad forehead
  • Facial cleft

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
