A genetic disorder is a condition caused by abnormalities in an individual's DNA, which can affect development, health, and function. These disorders can be inherited or caused by mutations that occur during cell division or environmental factors. Examples include sickle cell anemia, cystic fibrosis, and Huntington's disease. Genetic disorders can have varying levels of severity and may present physical, cognitive, or behavioral symptoms. Understanding genetic disorders is crucial for diagnosis, management, and developing potential therapies, emphasizing the importance of genetic research and counseling in medicine.
