Living with Acrocephalopolydactyly

An extremely rare genetic condition with a very large birth weight, swelling, short limbs, and extra fingers or toes.

Understanding Acrocephalopolydactyly

Acrocephalopolydactyly is an extremely rare autosomal recessive disorder; fewer than 10 cases have been reported.

It is marked by a very large birth weight, a swollen, round body, short limbs, extra fingers or toes, and thick skin. Facial features include slanted eyes and wide-set eyes. Kidney differences are part of it. Some people also have an enlarged liver and spleen, early-closing skull seams, cleft palate, or undescended testes. GARD lists onset as the newborn and infant period.

Signs & symptoms

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

  • Swollen, round body
  • Short limbs
  • Extra fingers or toes
  • Kidney differences
  • Enlarged liver and spleen
  • Early closing of skull seams

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

Diagnosis

  1. Talk with your doctor

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

  2. See a specialist

    Specialists who may be involved include bone and joint specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    World Craniofacial Foundation may keep lists of experts for this condition.
