PMF is an uncommon disease, with an annual incidence of approximately 0.5-1.5 cases per 100,000 individuals in the United States. In addition to White individuals, an increased prevalence rate of PMF has been noted in Ashkenazi Jews. In an epidemiologic study in 339 patients with myeloproliferative disorders in northern Israel, incidence of PMF was found to be 10- and 20-fold higher in Ashkenazi Jews than in Sephardic Jews and Arabs, respectively.
PMF can occur at any age; however, most cases are in individuals over 50 years, with the median age at diagnosis being ~65 years.
