Fanconi anaemia (FA) is an autosomal recessive genetic disorder. The disorder is passed from parents to their children. FA occurs when both parents pass the same faulty FA gene to their child.
People who have only one faulty FA gene are FA carriers. Carriers don’t have FA, but they can pass the faulty gene to their children.
If both of the parents have a faulty FA gene, the child has:
- A 25%chance of having FA
- A 25% percent chance of not having FA
- A 50% percent chance of being an FA carrier
Where there is a family history of FA, children are at risk of inheriting on or more faulty FA gene. Carriers of FA are unlikely to develop any symptoms.
