Living with Osteopetrosis

A group of bone diseases in which bones become unusually dense but break easily, from mild to severe.

Understanding Osteopetrosis

Osteopetrosis is a bone disease that makes bone tissue unusually dense and compact, and also prone to breaking.

Types are usually separated by inheritance and severity. The autosomal dominant type (Albers-Schönberg disease) is typically the mildest, and some people have no symptoms. The autosomal recessive type is more severe and shows in early infancy, with high fracture risk, dense skull bones pinching nerves, and bone marrow problems causing bleeding, anemia, and infections. GARD lists onset as any time in life.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on its summary, features may include:

  • Bones that break after minor injury
  • Curved spine (scoliosis) and other spine differences
  • Arthritis in the hips
  • Bone infection (osteomyelitis)
  • Vision loss, hearing loss, or face weakness from pinched nerves
  • Anemia, bleeding, and repeated infections in severe forms

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

    Little People of America may keep lists of experts for this condition.

  • Connect with Little People of America
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which type of osteopetrosis do I or my child have?
How should bone marrow and blood counts be monitored?
Which genetic testing would help my family?
