Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine whether cytokine gene polymorphisms affect the progression or response to therapy of bone marrow failure disorders. Cytokine genes instruct cells to produce proteins called cytokines that influence immune system response. As with many genes, the cytokine genes differ slightly from person to person. These differences are called gene polymorphisms. Different patients with the same bone marrow failure disease often progress and respond to treatment differently. This study will look at the possible role of cytokine gene polymorphisms in these differences. Patients between 2 and 80 years old who have participated in an NHLBI Hematology Branch treatment protocol for acquired aplastic anemia, myelodysplastic syndrome, or pure red cell aplasia are recruited to participate in this study. Blood collected and stored at the time of screening for the treatment protocol will be tested for cytokine gene polymorphisms. No additional tests, procedures, or treatments are involved in this study.
