Living with PI4KA-related disorder

A group of conditions caused by changes in the PI4KA gene, affecting the nervous system, gut, and immune system.

Understanding PI4KA-related disorder

PI4KA-related disorder is any condition caused by a change in the PI4KA gene.

It mainly involves nervous system problems, gut problems such as blocked or missing sections of the intestine and inflammatory bowel disease, and immune system weakness. Onset is typically before birth or in early childhood. Rarely, a person has later-onset hereditary spastic paraplegia (leg stiffness).

Signs & symptoms

GARD doesn't list a symptom list, but the summary describes:

  • Stiff muscles in the legs (spasticity)
  • Delays in development
  • Intellectual disability
  • Seizures
  • Problems with balance and coordination (ataxia)
  • Intestinal differences or inflammatory bowel disease

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
