Living with Hereditary spastic paraplegia 2

A rare X-linked condition affecting the brain's white matter, causing a spastic walk and automatic-function problems.

Understanding Hereditary spastic paraplegia 2

Hereditary spastic paraplegia 2 is a rare X-linked leukodystrophy (a condition of the brain's white matter) with a spastic walk and autonomic problems.

Autonomic means automatic body functions, such as bladder and bowel control. When other nervous system signs such as intellectual disability, poor balance, or movement changes occur, it is called complicated SPG. It starts in childhood.

Signs & symptoms

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

  • Spastic walk
  • Stiff muscles (spasticity)
  • Muscle weakness
  • Brisk reflexes
  • Bladder and bowel control problems
  • Optic nerve damage

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, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in PLP1 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

    Pelizaeus-Merzbacher Disease Foundation, Spastic Paraplegia Foundation and United Leukodystrophy Foundation may keep lists of experts for this condition.
