KEY CONCEPT Genetics provides a basis for new medical treatments.

Genetic screening can detect genetic disorders. Genetic screening involves the testing of DNA. determines risk of having or passing on a genetic disorder used to detect specific genes or proteins can detect some genes related to an increased risk of cancer can detect some genes known to cause genetic disorders DMD N

Gene therapy is the replacement of faulty genes. Gene therapy replaces defective or missing genes, or adds new genes, to treat a disease.

Several experimental techniques are used for gene therapy. genetically engineered viruses used to “infect” a patient’s cells insert gene to stimulate immune system to attack cancer cells insert “suicide” genes into cancer cells that activate a drug

Gene therapy has many technical challenges. inserting gene into correct cells controlling gene expression determining effect on other genes
