Living with Osteogenesis imperfecta type 5

A moderate form of osteogenesis imperfecta with fragile bones, short stature, and overgrown bone healing tissue.

Understanding Osteogenesis imperfecta type 5

Osteogenesis imperfecta type 5 is a moderate form of osteogenesis imperfecta with fragile bones and low bone mass.

Fractures vary in severity. Other features include bone changes at birth, short stature, a dislocated forearm bone at the elbow, and extra-thick healing tissue (hyperplastic callus), especially during fast growth. Whites of the eyes are normal, and dentinogenesis imperfecta is absent. GARD lists newborn and infant years as the usual onset.

Signs & symptoms

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

  • Repeated fractures
  • Thin bones (osteopenia)
  • Short stature
  • Extra-thick healing tissue after fractures (hyperplastic callus)
  • Dislocated elbow bone (radial head)
  • Limited turning of the forearm

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. Consider genetic testing

    Changes in IFITM5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Osteogenesis Imperfecta Foundation and Children's Brittle Bone Foundation may keep lists of experts for this condition.
