    ### Instruction:
    What are the genetic changes related to Carney complex ?
    ### Response:
    Mutations in the PRKAR1A gene cause most cases of Carney complex. This gene provides instructions for making one part (subunit) of an enzyme called protein kinase A, which promotes cell growth and division (proliferation). The subunit produced from the PRKAR1A gene, called type 1 alpha, helps control whether protein kinase A is turned on or off.
