  Purpose

The purpose of this study is to collect peripheral blood and bone marrow aspirate samples from thalassemia patients in Tehran, in a collaborative effort to develop an erythroid lineage specific chimerism assay applicable to patients with thalassemia. Development of such an assay would be useful both for identification of the exact mutation causing the disease, as well as for providing a direct method to measure and monitor the kinetics of donor erythropoiesis in this patient population following transplant.


Condition

Detailed Description:
  • In the first phase of the study we will develop a panel of reagents designed to identify predominant thalassemia mutations in the Iranian population, as well as alternative highly variable erythroid specific polymorphisms. To determine how informative this panel is, these reagents will be applied to samples collected from patients homozygous for the disorder, and compared to patients with thalassemia trait and normal Iranian donors.
  • In the second phase, we propose to serially measure and compare erythroid lineage chimerism with overall genomic chimerism following transplant. Samples will be collected from participants before and at 1, 2, 3, 6 and 12 months following transplant and cryopreserved. Peripheral blood from the stem cell donor will also be collected and cryopreserved. Participants will undergo myeloablative or nonmyeloablative transplant.
