Why testing relatives is important
Most mutations are inherited from your mother or your father. This means that your relatives on that side of the family may also have the same mutation. Additionally, each of your siblings and each of your children has a 50% chance of inheriting this mutation.
Knowing that you have a mutation allows you and your healthcare provider to create a personalized screening plan, which increases the chance of early detection.
Learning that you haven’t inherited a family mutation is useful information, as well, as it means your children will not inherit it.
