Living with Hereditary spastic paraplegia 43

A complex type of hereditary spastic paraplegia starting in childhood, with leg stiffness and severe wasting of the hands and feet.

Understanding Hereditary spastic paraplegia 43

Hereditary spastic paraplegia 43 is a rare, complex form of hereditary spastic paraplegia that starts between childhood and the teen years.

Leg stiffness gets worse over time with walking problems, weakness, and severe wasting of the hands and feet. Some people also have stiff joints, loss of feeling in the hands and feet, depression, memory loss, loss of vision from optic nerve damage, and iron buildup in the brain.

Signs & symptoms

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

  • Stiff legs (spasticity)
  • Spastic walk
  • Wasting of muscles in the hands and feet
  • Stiff joints (contractures)
  • High-arched feet (pes cavus)
  • Poor fine motor coordination

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 C19orf12 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.
