Living with Craniofrontonasal dysplasia-Poland anomaly syndrome

A rare syndrome with early skull bone closure, differences of the chest muscle, and genital and breast differences.

Understanding Craniofrontonasal dysplasia-Poland anomaly syndrome

Craniofrontonasal dysplasia-Poland anomaly syndrome is a rare syndrome with several body differences, present from birth.

It combines early closure of skull bones (craniosynostosis), Poland anomaly (underdeveloped chest and shoulder muscles on one side), craniofrontonasal dysplasia (differences of the skull, forehead, and nose), and genital and breast differences.

Signs & symptoms

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

  • Early closure of skull bones (craniosynostosis)
  • Underdeveloped shoulder muscles
  • Small or missing nipples
  • Cleft or groove in the nose
  • Crossed eyes (strabismus)
  • Genital differences

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, genetic specialists, maternal-fetal medicine specialists and women’s reproductive health specialists.

  3. Ask which tests can help

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