Carrier Information

A "carrier" is a person who has a gene with a certain trait (i.e. hemophilia), but who does not typically exhibit that trait themselves. Since the defective gene for hemophilia resides with the X chromosome, one of your X chromosomes is "normal" and the other has the defective gene. Therefore, you have a 50% chance of providing the defective gene in a pregnancy. If this happens, and the child is male, he will have hemophilia. If the child is female, she will be a carrier who also has a 50% chance of passing along the hemophilia gene.

You Are a Carrier If:

• Your father had hemophilia and you are female;
• You are a mother of more than one child with hemophilia; or
• You are a mother who has one child and another blood relative with hemophilia (such as a brother, uncle, etc.)
