This document discusses how genetic disorders are detected and potential treatments using gene therapy. It explains that genetic disorders can be monogenic, caused by a single gene defect, or polygenic, caused by multiple gene defects. Detecting genetic disorders involves pedigree analysis, genetic mapping to identify markers linked to disease genes, and sequencing genes to enable accurate diagnosis. Cystic fibrosis and Duchenne muscular dystrophy are discussed as examples. Gene therapy aims to replace defective genes with healthy copies to treat genetic diseases, but vectors are needed to safely deliver genes to target cells. Ethical issues around gene therapy playing God must also be considered.
