Who Gets PNH?

Who Gets PNH?

PNH is a rare disease, but that doesn’t mean you’re alone. It affects about 8,000 to 10,000 people in North America and Western Europe.

  • Both men and women can get PNH
  • PNH occurs across all races
  • PNH can occur at any age; the average age at diagnosis is in the early 30s

No one knows what causes PNH. It is an acquired disease, which means it develops in some people over time. PNH is not contagious, and PNH is not genetic, so it is not inherited from a family member and cannot be passed on to children.

Is PNH the same for everyone?

PNH comes with a wide range of signs you can see and symptoms you can feel—and even some symptoms you can’t feel. Everyone is different, so people with PNH may experience different signs and symptoms.

In addition, the signs and symptoms of PNH are often similar to other diseases. This is what makes PNH tough to diagnose. There’s no one sign, symptom, or lab result that defines PNH. Your doctor will consider all your signs and symptoms, in addition to your lab test results.

Keep track of how you are feeling using the Symptoms Checkup Chart.
