Primary myelofibrosis causes scarring of the bone marrow. Familial clustering exists and the same driver mutations as polycythaemia vera and essential thrombocythaemia are involved.
How Genetic Is Myelofibrosis?
Genetics plays a meaningful role in Myelofibrosis, with heritability estimated at around 15%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Myelofibrosis: JAK2,CALR,MPL. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Myelofibrosis?
Family history does matter. Having close relatives with Myelofibrosis can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
