    ### Instruction:
    What are the genetic changes related to idiopathic pulmonary fibrosis ?
    ### Response:
    The cause of idiopathic pulmonary fibrosis is unknown, although the disease probably results from a combination of genetic and environmental factors. It is likely that genetic changes increase a person's risk of developing idiopathic pulmonary fibrosis, and then exposure to certain environmental factors triggers the disease.
