Living with Acrofrontofacionasal dysostosis

A rare condition present at birth with differences in the face, hands, and feet, and severe intellectual disability.

Understanding Acrofrontofacionasal dysostosis

Acrofrontofacionasal dysostosis is a rare condition with facial and skeletal differences and severe intellectual disability.

Facial differences include a broad forehead, droopy eyelids, cleft palate, and a cleft in the upper lip. Hands may have broad thumbs and absent nails. Some people have genital and urinary tract differences. GARD lists onset as newborn.

Signs & symptoms

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

  • Severe intellectual disability
  • Cleft palate
  • Cleft upper lip
  • Droopy upper eyelids (ptosis)
  • Broad thumb
  • Absent nails

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

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
