  1. KEY CONCEPT Genetics provides a basis for new medical treatments.

  2. DMD N Genetic screening can detect genetic disorders. • Genetic screening involves the testing of DNA. • determines risk of havingor passing on a geneticdisorder • used to detect specificgenes or proteins • can detect some genesrelated to an increasedrisk of cancer • can detect some genesknown to cause geneticdisorders

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

  4. 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

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