Genetic testing and genetic counseling on how to deal with the results of tests will certainly grow at a rapid rate, creating a burgeoning challenge for pastors and Catholic health care providers. However, genetic testing raises and will continue to raise moral issues for the individual, for the family, for racial or ethnic groups, and for society as a whole. The Church has a responsibility to offer insights based on its venerable tradition and current experience, not only to inform consciences and assist in the formation of wise public policy, but also to keep tradition vital. Most often genetic tests show no disease, relieving anxiety. Moreover, the Catholic Church welcomes testing when it functions as an extension of sound medical practice.
Genetic testing can assist sound decision-making in a wide range of situations.
It is most commonly employed to detect problems with newborns. Moreover, millions of Americans are hospitalized every year because of hereditary disease and congenital defects. To the extent that genetic testing sets the stage for a cure or effective therapy, it is a blessing. Testing has legitimate uses even in the delicate arena of human reproduction. Young couples considering marriage may want to know whether one or both partners carry a gene associated with mental retardation, cystic fibrosis, breast cancer, or some other heritable condition.
