Sickle cell disease is a recessive genetic disorder caused by a single mutation in both copies of a gene coding for beta - globin, a protein that forms part of the oxygen - carrying molecule hemoglobin.

In sickle cell anemia, a single genetic mutation leads to abnormal, crescent - shaped red blood cells that clot in tiny blood vessels throughout the body, causing severe pain and eventual organ damage.

In sickle cell disease, a mutation in the beta - globin gene causes hemoglobin to polymerize under low - oxygen conditions in body tissues, deforming red blood cells.

Those mutations are known to protect against sickle cell anemia.

They have a disruptive mutation in the gene for the blood cell molecule hemoglobin; as a result, their red blood cells typically take on a sickle shape, which causes them to clog up blood vessels, leading to intense pain, especially in the long limb bones.

Exciting clinical applications of gene editing include correcting the mutation in the bone marrow stem cells of patients with sickle cell disease or hemophilia.

The Genomics Facility also is working with other teams studying mutations in bladder cancer tumors; genetic mechanisms of sickle cell disease; viruses in Lake Michigan; and many other projects.

In this way, the mutation is somewhat similar to sickle cell anemia in humans, where having one copy of a mutated gene gives one an immunity to malaria, while two copies causes a painful, life - threatening illness.
