Research Abstract

To understand the mechanism of leukemogensis in Down syndrome, we investigate the genes on chromosome 21 and identified ERG, RUNX1 and BACH1 as the candidates of the causative genes. JAK3 activating mutations were identified in about 10% of preleukemia (TMD) in Down syndrome. GATA1 mutations affected the expression levels of GATA1s protein. GATA1s low mutations in TMD were significantly associated with a risk of progression to acute megakaryoblastic leukemia and lower WBC counts.
