SCT, or Sickle Cell Trait, is a genetic condition where a person inherits one normal hemoglobin gene and one sickle hemoglobin gene. Individuals with SCT usually do not experience symptoms of sickle cell disease but can pass the sickle gene to their children. People with SCT typically lead normal lives and have a normal life expectancy. However, under extreme conditions, such as high altitude or intense physical exertion, they may experience some complications. It is important for individuals with SCT to be aware of their condition, especially when considering family planning.
