How genes affect red blood cell function in sickle cell disease

Researchers are studying how genetic variations in a gene called PKLR affect the way red blood cells function in people with sickle cell disease. By collecting blood samples from people with sickle cell disease, people with sickle cell trait, and healthy volunteers, they want to understand why some people have more severe symptoms than others and whether certain genetic variations might protect against sickling or make it worse.

Sickle cell disease happens when hemoglobin (a protein in red blood cells) clumps together and damages cells. Recent research suggests that variations in the PKLR gene might influence how likely this clumping is to happen, but scientists don't yet understand exactly how these genetic differences affect individual patients. This study aims to fill that gap so doctors can better understand and eventually treat the disease.
