Hereditary conditions are health issues that are passed down from parents to their children through genes. These conditions can be caused by mutations in specific genes, which may lead to various physical or mental health problems. Examples include cystic fibrosis, sickle cell anemia, and Huntington's disease. People with hereditary conditions may experience symptoms at different ages, and the severity can vary widely. Genetic testing can help identify these conditions, allowing for early diagnosis and management. Understanding family history is also important, as it can provide insights into potential hereditary risks for future generations.
