Overview
Polycythemia vera is caused by a mutation in the JAK2 gene (V617F mutation). This mutation occurs in more than 98% of cases of polycythemia vera. The JAK2 exon 12 mutation occurs in a small proportion of patients. There are no other causes of this disease.
Causes
Common Causes
Common causes of polycythemia vera may include:[1]
- JAK2 V617F gene mutation. This mutation is found in more than 95% of cases of polycythemia vera. It is a point mutation in which valine is replaced by phenylalanine at the 617th position of the gene. The mutation occurs in exon 14 of the JAK2 gene.
Less Common Causes
Less common causes of polycythemia vera include:[1]
- JAK2 exon 12 gene mutation
- LNK (SH2B3) gene mutation (inhibitor of JAK-STAT signaling pathway)
- TET2 gene mutation
- SF3B1 gene mutation (involved in RNA splicing)
- DNMT3A gene mutation (involved in epigenetic regulation)
- ASXL1 gene mutation
Genetic Causes
- Polycythemia vera is caused by a mutation in various genes. They include:[1]
- JAK2
- TET2
- SF3B1
- DNMT3A
- ASXL1
