Demo: Carrier Status

A “carrier” is the term for a person who “carries” a gene change (also called a gene mutation) on one of the two copies of a certain gene.


  • A carrier does not have the disorder, but his or her children may be at risk for inheriting it.
  • If one parent is a carrier and the other parent is not, each of their children has a 1 in 2 (50 percent) chance of also being a carrier. Most of the time, their child(ren) would not have the disorder.
  • If both parents are carriers, for each pregnancy there is a 1 in 4 (25 percent) chance the child will inherit the condition. There is a 3 out of 4 (75 percent) chance the child will not inherit the disorder.
  • If the child is a carrier, each of the parents may also be a carrier.
