Certain genetic disorders only manifest if the individual carries two copies of the defective gene in question. Carrier testing is used to determine if a healthy individual carries a single copy of a genetic mutation, which when passed to a child might cause genetic disease.
The testing of a healthy individual for mutations in a particular gene. Usually refers to unaffected carriers of a recessive condition, e.g. cystic fibrosis.
A test to determine what people carry an abnormal gene.
Genetic testing to identify individuals who carry a disease-causing gene which could be inherited by their children. Carrier testing is designed for healthy people with a family history of a certain disease.
(synonyms: carrier detection, heterozygote testing) Testing used to identify usually asymptomatic individuals who have a gene mutation for an autosomal recessive or X-linked recessive disorder Related Terms: X-linked recessive ; autosomal recessive ; carrier ; heterozygote ; homozygote ; molecular genetic testing ; mutation
testing to identify individuals who carry disease-causing recessive genes that could be inherited by their children. Carrier testing is designed for healthy people who have no symptoms of disease, but who are known to be at high risk because of family history.
Genetic testing of an apparently healthy person to determine whether that person carries a recessive gene that could cause disease in their offspring.
testing performed to determine whether a person carries one copy of an altered gene for a particular recessive disease.
Tests that can determine whether a person carries disease-causing recessive genes that could be inherited by their children. If you are a healthy person who is considered to be at high risk because of your family history, carrier testing is an option for you.
