Associated Genetic Biomarkers

Overview

NCI Definition: A clonal hematopoietic disorder characterized by dysplasia and ineffective hematopoiesis in one or more of the hematopoietic cell lines. The dysplasia may be accompanied by an increase in myeloblasts, but the number is less than 20%, which, according to the WHO guidelines, is the requisite threshold for the diagnosis of acute myeloid leukemia. It may occur de novo or as a result of exposure to alkylating agents and/or radiotherapy. (WHO, 2001) [1]

Myelodysplastic syndromess most frequently harbor alterations in ASXL1, ETV6, TET2, TP53, and CDKN2A [2].

Most Commonly Altered Genes in Myelodysplastic Syndromes

ASXL1 Mutation, ETV6 Mutation, ETV6 Frameshift, ETV6 E21Gfs*60, and ASXL1 Frameshift are the most common alterations in myelodysplastic syndromes [2].
