Living with Hereditary spastic paraplegia 53

A very rare, complex type of hereditary spastic paraplegia starting in infancy, with motor and speech delay.

Understanding Hereditary spastic paraplegia 53

Hereditary spastic paraplegia 53 (SPG53) is a very rare, complex form of hereditary spastic paraplegia that starts early.

Stiffness begins in the legs and moves to the arms. It comes with delayed motor and speech development, mild to moderate thinking difficulty, skeletal differences such as a rounded upper back and pigeon chest, excess body hair, and mildly reduced vibration sense. It starts in infancy.

Signs & symptoms

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

  • Stiff muscles (spasticity)
  • Delayed speech and language
  • Very flexible joints
  • Rounded upper back (kyphosis)
  • Pigeon chest (pectus carinatum)
  • Brisk reflexes in the arms

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 VPS37A 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

    Spastic Paraplegia Foundation may keep lists of experts for this condition.
