What causes Sickle Cell Disease?

Sickle cell disease is an inherited blood disorder. A person will be born with sickle cell disease only if two genes are inherited—one from each parent. A person who inherits just one gene is healthy and is called a "carrier". If two carriers have children together, there is a 1 in 4 chance that their children will have sickle cell disease. #WorldSickleCellDiseaseDay
