A genetic disorder is a health condition caused by abnormalities in an individual's DNA. These disorders can result from mutations in a single gene, multiple genes, or even changes in entire chromosomes. Examples include cystic fibrosis, sickle cell anemia, and Down syndrome. Genetic disorders can be inherited from parents or occur spontaneously. Symptoms of genetic disorders vary widely, ranging from mild to severe, and can affect various body systems. Diagnosis often involves genetic testing, which helps identify specific mutations. While some genetic disorders have no cure, treatments and therapies can help manage symptoms and improve quality of life.
