How is NF1 inherited?

About half the people with NF1 are born to unaffected parents, following a genetic change in the egg or sperm. People with NF1 may pass the condition on to their children. With one affected parent, each child has a one-in-two chance of being born with NF1, and a one-in-two chance of being unaffected. Those born with NF1 may pass the condition on to their own children, while those unaffected will not.
