Living with Autosomal recessive spastic paraplegia type 67

An extremely rare inherited condition with developmental delay and leg stiffness that begins in infancy or childhood.

Understanding Autosomal recessive spastic paraplegia type 67

Autosomal recessive spastic paraplegia type 67 is an extremely rare complex hereditary spastic paraplegia with global developmental delay and slowly worsening stiffness.

It starts in infancy or childhood with developmental delay and increasing stiffness and tremor in the limbs. Reflexes are overactive. Some people have mild intellectual disability. Muscle wasting and differences in the cerebellum are also reported.

Signs & symptoms

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

  • Global developmental delay
  • Stiffness in the legs (spasticity)
  • Spastic walk
  • Limb tremor
  • Overactive reflexes
  • Muscle wasting

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 PGAP1 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.
