• A blood disorder that causes red blood cells to:
- Elongate-Clog arteries
• Blood cells are shaped like “Sickles,” or a crescent shape
What is it?

What is it?• Normal blood cells can survive up
to 120 days
• Sickled blood cells can only live 10 to 20 days, and the bone marrow can not make enough cells to keep up.
• Anemia is a disease where the person has a lower number of red blood cells than normal.
• Most common inherited blood disorder: 70,000 to 80,000 Americans
affected. 1 in 500 African Americans affected. 1 in 1000 Hispanic Americans
affected.

• Blood cells become stiff and sticky which causes unnecessary clotting.
• Pain in any organ or joint.
• More susceptible to other diseases.
• Clotting causes serious infection, organ damage, and strokes.
Symptoms

• Other symptoms include:– Shortness of breath
– Dizziness
– Headaches
– Coldness in the hands and feet
– Paler than normal skin or mucous membranes (the tissue that lines your nose, mouth, and other organs and body cavities)
– Jaundice (a yellowish color of the skin or whites of the eyes)
– Sometimes swelling of the hands and feet.

• No cure
• Some treatments can help, such as Blood and Marrow stem cell transplants
• Most people with this disease are living to their forties, fifties, and higher.
Treatments

• Sickle Cell Anemia is inherited
• Life long
• From birth
• Two genes for sickle Hemoglobin, one from each parent.
Genetics

• If one parent gives a gene for sickle Hemoglobin, and the other gives a normal gene, then…
• They have what is called Sickle Cell Trait
• This is not the same as Sickle Cell Anemia. It means that the person caries one trait of the disease.
• Sickle Cell Anemia is due to a mutation in the HBB gene, which causes the hemoglobin to become deformed.
• Is a recessive trait.
