    ### Instruction:
    Is hereditary paraganglioma-pheochromocytoma inherited ?
    ### Response:
    Hereditary paraganglioma-pheochromocytoma is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing tumors. An additional mutation that deletes the normal copy of the gene is needed to cause the condition.
