Living with Weismann-Netter syndrome

A rare genetic bone condition, present from birth, with bowed leg bones, short stature, and other bone differences.

Understanding Weismann-Netter syndrome

Weismann-Netter syndrome is a rare genetic bone condition in which the lower leg bones bow forward.

The shin and calf bones (tibia and fibula) bow and thicken. People are short in height and may have a curved spine, a tilted tailbone, and other bone differences. Walking often starts later than usual. Signs are present at birth.

Signs & symptoms

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

  • Bowed shin and calf bones
  • Bowed thigh bones
  • Severe short stature
  • Curved spine (scoliosis or kyphosis)
  • Squared hip bones
  • Intellectual disability

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.
