Research summary
We will functionally evaluate mutation combinations that contribute to subclone
expansion.
Myelodysplastic syndrome (MDS) is the most common adult myeloid blood malignancy with a median age of diagnosis of 70-71. In addition to the negative impact of anemias on patients’ quality of life, approximately 30% of patients will develop a secondary acute myeloid leukemia (sAML). Based on the World Health’s Organization diagnostic criteria, MDS diagnosis includes persistent peripheral cytopenias, morphologic dysplasia of
hematopoietic cells, and a bone marrow blast count of less than 20%. Even with current advances in sequencing technologies, the mechanisms driving abnormal hematopoietic cell differentiation, maturation arrest and clonal expansion are not fully understood. We want to better understand mechanisms that will be essential to optimize a patient-centered treatment approach for MDS patients.
