Novel RUNX1 Variation in B-cell Acute Lymphoblastic Leukemia.

ABSTRACT: Acute lymphoblastic leukemia (ALL) is a malignant disease of hematopoietic stem cells. B cell ALL (B-ALL) is characterized by highly proliferative and poorly differentiated progenitor B cells in the bone marrow. Chromosomal rearrangements, aberrant cell signaling, and mutations lead to dysregulated cell cycle and clonal proliferation of abnormal B cell progenitors. In this study, we aimed to examine hot spot genetic variations in the RUNX1, IDH2, and IL2RA genes in a group of (n=52) pediatric B-ALL. Sanger sequencing results revealed a rare RUNX1 variant p.Leu148Gln in one B-ALL patient with disease recurrence. Additionally, common intronic variations rs12358961 and rs11256369 of IL2RA were determined in two patients. None of the patients had the IDH2 variant. <
