Living with Aniridia-ptosis-intellectual disability-familial obesity syndrome

An extremely rare syndrome described in one family, with eye differences, intellectual disability, and obesity.

Understanding Aniridia-ptosis-intellectual disability-familial obesity syndrome

Aniridia-ptosis-intellectual disability-familial obesity syndrome is an extremely rare syndrome described in a mother and her two children.

It combines eye differences with other body features. The eye differences include a partly or fully missing iris, drooping eyelids, shaky eye movements, clouded lenses, and low sharpness of vision. The two children had intellectual disability and obesity. The mother had hair loss, heart differences, and frequent miscarriages. GARD says there have been no further descriptions since 1986.

Signs & symptoms

Symptoms vary. GARD lists these among the most common:

  • Missing or small iris
  • Drooping upper eyelid (ptosis)
  • Nearsightedness (myopia)
  • Cloudy cornea
  • Intellectual disability
  • Reduced vision

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