HBB: The Gene Associated with Sickle Cell Anemia
Official Gene Symbol: HBB
Name of Gene Product: hemoglobin, beta
Alternate Name of Gene Product: beta globin
Locus: 11p15.5 - The HBB gene is found in region 15.5 on the short (p) arm of human chromosome 11.

Bone marrow transplant can cure Sickle Cell Anemia
Sickle Cell Information Center News Page
• This procedure replaces bone marrow affected by sickle cell anemia with healthy bone marrow from a donor who doesn't have the disease. It can be a cure, but the procedure is risky, and it's difficult to find suitable donors. Researchers are still studying bone marrow transplants for people with sickle cell anemia. Currently, the procedure is recommended only for people who have significant symptoms and problems from sickle cell anemia.
