What Is Niemann-Pick Disease Type C?

Inborn Error of Energy Metabolism

Niemann-Pick disease is a group of rare inherited conditions caused by a faulty gene. Niemann-Pick disease type C (NPC) is a subtype.

Children with NPC lack a protein that the body needs to break down fats and cholesterol within cells. As a result, these substances build up in cells, causing progressive damage to the brain, liver, lungs, and other organs.

Symptoms most often begin to appear between ages 4 and 10.

Children with NPC may have trouble moving their eyes up and down.

Other NPC symptoms may include:

  • Jaundice.
  • Seizures.
  • Breathing problems.

  • Likely next steps for your child.
  • NPC treatment options.
  • Ways to help your child's quality of life at home.

By the end of your visit, you'll have a NPC care plan tailored to your child's needs. We'll also schedule a follow-up visit.

You'll meet our nurse practitioner. You can contact them by phone or video conference with any concerns before your next visit.

Before you leave, please ask us about your child's NPC, treatment, or anything else on your mind.

How long will I need to wait for my child's test results?
