Hemoglobin sickle-beta thalassemia, also known as sickle beta thalassemia and sickle cell-beta thalassemia, is considered a variant form of sickle cell anemia.[6] This condition occurs when an individual inherits two altered HBB genes -- one from a parent who is a carrier of beta thalassemia and and the other from a parent who is a carrier of sickle cell anemia. This condition is inherited in an autosomal recessive fashion and is caused by mutations in the hemoglobin, beta (HBB) gene.[1][2]
