Living with Acrofrontofacionasal dysostosis type 2

A very rare condition present at birth with facial and hand differences plus genital and urinary differences.

Understanding Acrofrontofacionasal dysostosis type 2

Acrofrontofacionasal dysostosis type 2 is a very rare syndrome that includes genitourinary differences.

It combines facial, hand, and foot differences with differences in the genitals and urinary tract. Features can include a broad forehead, bulging eyes, droopy eyelids, extra or webbed fingers, and hypospadias. GARD lists onset as newborn.

Signs & symptoms

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

  • Broad forehead
  • Bulging eyes
  • Droopy upper eyelids (ptosis)
  • Extra thumb or webbed fingers
  • Hypospadias or epispadias
  • Glaucoma

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