Characterization of T-cell Repertoire in Patients With Acute Myeloid Leukemia Undergoing Donor Stem Cell Transplant

This research trial studies characterization of T-cell repertoire through next-generation sequencing in patients with acute myeloid leukemia undergoing stem cell transplant. Characterizing T-cell repertoire may help to understand if immune system plays a significant role in high risk patients with acute myeloid leukemia.

PRIMARY OBJECTIVES: I. Characterize the T cell receptor (TCR) repertoire in acute myeloid leukemia (AML) patients before and after receiving hematologic stem cell transplantation (HSCT). II. Identify molecular changes (germline variants and somatic mutations) that contribute to shaping the TCR repertoire. OUTLINE: Patents undergo collection of blood samples before, on day 100, and 1 year after HSCT. Donors undergo collection of blood at the time of HSCT for ribonucleic acid (RNA)-based next generation sequencing of TCRA and TCRB genes.
