Living with Osteogenesis imperfecta type 7

A severe recessive form of osteogenesis imperfecta with fragile bones and fractures present at birth.

Understanding Osteogenesis imperfecta type 7

Osteogenesis imperfecta type 7 is an autosomal recessive, severe form of osteogenesis imperfecta, a connective tissue disorder with fragile bones and low bone mass.

GARD lists multiple fractures present at birth, bowed legs, short upper limbs, curved spine, and extra small bones in the skull sutures among its features.

Signs & symptoms

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

  • Multiple fractures at birth
  • Repeated fractures
  • Bowed legs
  • Short upper arms and thighs
  • Curved spine (scoliosis)
  • Blue-gray tint to the whites of the eyes

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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

  4. Connect with expert centers

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