Overview
Essential thrombocytosis may be caused by a mutation in the janus kinase 2 (JAK2) gene (in >50% of the patients), CALR, MPL, or THPO genes. Approximately 90% of patients have JAK-STAT pathway driver variants: JAK2 (64%), CALR (23%), and MPL (4%). About 10% are triple-negative (no JAK2/CALR/MPL variant).[1]
Causes
Essential thrombocytosis may be caused by a mutation in one of the following genes:[2]
- Janus kinase 2 (JAK2) gene (in 50% of the patients)
- CALRgene
- MPL gene
- THPO gene
Approximately 90% of patients have JAK-STAT pathway driver variants: JAK2 (64%), CALR (23%), and MPL (4%). About 10% are triple-negative (no JAK2/CALR/MPL variant).
