Living with Stüve-Wiedemann syndrome 1

A condition present from birth with bowed leg bones and trouble with automatic body functions like feeding and body temperature.

Understanding Stüve-Wiedemann syndrome 1

Stüve-Wiedemann syndrome 1 is a severe condition with bone differences and problems with the autonomic nervous system.

The autonomic nervous system controls automatic body processes such as breathing rate and body temperature. It is apparent from birth. Key features are bowed leg bones, feeding and swallowing problems, and episodes of dangerously high body temperature. Babies may also have bowed arms, permanently bent fingers and toes, and stiff elbows and knees. As children grow, leg bowing worsens and they may develop a curved spine and easily broken bones.

Signs & symptoms

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

  • Bowed leg bones
  • Feeding and swallowing trouble
  • Episodes of high body temperature
  • Breathing problems
  • Stiff, bent joints (contractures)
  • Heavy sweating or less ability to feel pain

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