Persons with this disease have blood cells that are missing a gene called PIG-A. This gene allows a substance called glycosyl-phosphatidylinositol (GPI) to help certain proteins stick to cells.

Mutations in any of 10 different genes can affect the production of GPI. Only one gene, however, is always altered in PNH.
