    Sickle Cell Trait “Trait” is a word used to describe a person who has inherited one abnormal gene from one parent and a normal gene from the other parent. A person with sickle cell trait inherits one gene to make normal hemoglobin (A) and another gene to make some sickle cell hemoglobin (S). Sickle Cell Anemia is an inheritable disease that is transmitted in an autosomal recessive manner, meaning two copies of the aberrant gene must be inherited in order to acquire the disease. Sickle cell trait is a hemoglobin genotype AS and is generally regarded as a benign condition. However, individuals with sickle cell trait may have rare complications.

    Sickle Cell Disease is an inherited disorder that affects the hemoglobin, a molecule in red blood cells, which helps to deliver oxygen throughout the body. These are normal red blood cells with normal hemoglobin (AA hemoglobin). These cells appear round and are very flexible. These normal cells live for about 120 days. Any condition that affects normal blood flow can cause PH, including Sickle Cell Disease (SCD).
