MAIN
GLOSSARY
Carrier
A person who has a gene mutation that can cause a disease, but does not have any symptoms of the disease themself. The mutation is often recessive, which means that both copies of the gene have to be mutated in order for disease symptoms to develop. Carriers are able to pass the mutation on to their children and therefore have an increased chance of having a child with the disease.
