This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
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. The PKLR gene helps create a protein, called pyruvate kinase that is essential in normal functioning of the red blood cell. Differences in the PKLR gene, called genetic variants, may cause some changes in the pyruvate kinase protein and other proteins, that can affect functioning of the red blood cell adding to the effect of SCD. Researchers can study these differences by looking at DNA (the material that determines inherited characteristics). Objective: To study how the PKLR gene affects sickle cell disease. Eligibility: Adults ages 18-80 of African descent. They may have sickle cell disease or not. They must not have had a transfusion recently or have a known deficiency of pyruvate kinase. They cannot be pregnant. Design: Participants will be screened with questions. Participants will have blood drawn by needle in an arm vein. The blood will be genetically tested. Not much is known about how genes affect SCD, so the test results will not be shared with participants or their doctors. ...
Genotype -Phenotype Correlation of PKLR Variants With Pyruvate Kinase, 2,3-Diphosphglycerate and ATP Activities in Red Blood Cells of Patients With Sickle Cell Disease
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
