Overview
Common causes of paroxysmal nocturnal hemoglobinuria include a somatic mutation in the PIGA gene. Other causes include mutations in genes of TET2, SUZ12, U2AF1, and JAK2.
Causes
Life-threatening Causes
- Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. There are no life-threatening causes of paroxysmal nocturnal hemoglobinuria, however complications resulting from untreated disease name is common.
Genetic Causes
- Paroxysmal nocturnal hemoglobinuria is caused by a somatic mutation in the PIGA gene. The PIGA gene normally encodes phosphatidylinositol glycan class A.[1]
- Other gene mutations associated with paroxysmal nocturnal hemoglobinuria include the following genes:[2]
- TET2
- SUZ12
- U2AF1
- JAK2
