Living with Paget disease of bone 3

An inherited form of Paget disease of bone that can make bones enlarged, weak, painful, or misshapen.

Understanding Paget disease of bone 3

Paget disease of bone 3 is an inherited form of Paget disease of bone caused by changes in the SQSTM1 gene.

People with this condition have abnormal bone remodeling, which is the normal process of breaking down and rebuilding bone. This can lead to enlarged, weakened, painful, or deformed bones. It may run in families. It can raise the chance of problems such as fractures, hearing loss, and, rarely, certain bone tumors.

Signs & symptoms

GARD lists these features, though it doesn't have enough information on how common they are:

  • Bone pain
  • Breakdown of bone
  • Hearing loss
  • Bone cell cancer (rare)

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

    Bone Health & Osteoporosis Foundation and Cure VCP Disease, Inc. may keep lists of experts for this condition.
