Living with Hereditary sensorimotor neuropathy with hyperelastic skin

A rare inherited nerve condition with weakness in the hands and feet, stretchy skin, and a type of eye disease.

Understanding Hereditary sensorimotor neuropathy with hyperelastic skin

Hereditary sensorimotor neuropathy with hyperelastic skin is a rare inherited nerve disease with slowly worsening weakness in the arms and legs and stretchy skin.

Weakness and muscle wasting are mild to moderate and mostly in the hands and feet, with variable loss of feeling there. It also comes with age-related macular degeneration (an eye condition). Some people have very flexible joints in the hands and feet, a high palate, and minor bone differences. It can start at any time in life.

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Based on the summary, it can include:

  • Weakness in the hands and feet
  • Muscle wasting
  • Reduced feeling in the hands and feet
  • Stretchy skin
  • Macular degeneration in the eye
  • Very flexible joints in the hands and feet

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 brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in FBLN5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.
