Clinical trials: Natural History
Sickle Cell, PKLR Variants
Genotype -Phenotype Correlation of PKLR Variants With Pyruvate Kinase, 2,3-Diphosphglycerate and Adenosine Triphosphate Activities in Red Blood Cells of People With Sickle Cell Disease
Background: Some people with the same disorder on a genetic level have more complications than others. Researchers want to look for a link between the PKLR gene and sickle cell disease (SCD) symptoms.
