Sickle cell disease

Overview

What is sickle cell disease?

Sickle cell disease (SCD) is an inherited lifelong blood disorder that affects the shape of red blood cells. This disease affects people primarily of African and Hispanic descent.

Our red blood cells contain hemoglobin A, which carries oxygen to tissues in our body. In SCD, the hemoglobin found in red blood cells is different. It is called hemoglobin S. Red blood cells with hemoglobin S do not live as long as red blood cells with hemoglobin A. This means someone with hemoglobin S may not have enough red blood cells to bring oxygen and nutrients to the tissues in the body.

Hemoglobin S can cause the red blood cells to become crescent (sickle) shaped. When this happens, it becomes very difficult for red blood cells to make their way through small blood vessels and into tissues that need oxygen and nutrients. When tissues are unable to receive blood flow and nutrients, they can become damaged.

How common is sickle cell disease?

  • SCD affects approximately 100,000 Americans
  • SCD occurs in about 1 out of every 365 Black or African-American births
  • SCD occurs in about 1 out of every 16,300 Hispanic-American births
