Increased prevalence of polycythemia vera in parents of patients on polycythemia vera study group protocols.
An investigation of relatives of 652 patients entered on studies of the Polycythemia Vera Study Group yielded five documented cases of the disease among the parents of patients. When compared with expected values based on the Connecticut Tumor Registry and other population studies a significant increase was found in the lifetime incidence of polycythemia vera in parents of these patients.
