Living with Bruck syndrome 2

A genetic condition caused by changes in the PLOD2 gene that affects bone and joint development.

Understanding Bruck syndrome 2

Bruck syndrome 2 is a condition caused by a change in the PLOD2 gene, which affects the strength of bones and joints.

The gene makes an enzyme called telopeptide lysyl hydroxylase, which is important for forming strong bones and joints. When the gene is changed, bone and joint development is affected, leading to joint stiffness and bone differences.

Signs & symptoms

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

  • Stiff, bent joints (contractures)
  • Club feet
  • Easily broken bones
  • Thin bones (osteopenia)
  • Short stature
  • Bowed thigh bones

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.

Quick facts

InheritanceAutosomal Recessive

Changes in the PLOD2 gene cause this condition. It is autosomal recessive, which means a child inherits a changed copy of the gene from each parent.

Also known as: brks2; bruck syndrome caused by mutation in plod2; bruck syndrome type 2; plod2 bruck syndrome
