Sickle cell disorder is an inherited blood disease featured by defective hemoglobin. The condition affects the hemoglobin, or the red blood cells, and their tendency to conduct oxygen. The normal hemoglobin cells are round, smooth, and flexible, and thus, they can travel via the vessels in the body effortlessly.
