    ### Instruction:
    Is PDGFRB-associated chronic eosinophilic leukemia inherited ?
    ### Response:
    PDGFRB-associated chronic eosinophilic leukemia is not inherited and occurs in people with no history of the condition in their families. Chromosomal rearrangements that lead to a PDGFRB fusion gene are somatic mutations, which are mutations acquired during a person's lifetime and present only in certain cells.
