    ### Instruction:
    What are the genetic changes related to Fanconi anemia ?
    ### Response:
    Mutations in at least 15 genes can cause Fanconi anemia. Proteins produced from these genes are involved in a cell process known as the FA pathway. The FA pathway is turned on (activated) when the process of making new copies of DNA, called DNA replication, is blocked due to DNA damage.
