    ### Instruction:
    What are the genetic changes related to benign familial neonatal seizures ?
    ### Response:
    Mutations in two genes, KCNQ2 and KCNQ3, have been found to cause BFNS. Mutations in the KCNQ2 gene are a much more common cause of the condition than mutations in the KCNQ3 gene.  The KCNQ2 and KCNQ3 genes provide instructions for making proteins that interact to form potassium channels.
