Acquired a-Thalassemia Myelodysplastic Syndrome (ATMDS) is a very rare form of acquired thalassemia defined by a down-regulation of α globin synthesis in a myelodysplastic context. Herein we present the case of an 87-year-old man with myelodysplastic syndrome and a progressive microcytic anemia highlighted during his biological check-ups carried out over the years. Eventually, a rare ATRX gene mutation on exon 35 leading to a premature stop codon (p.R2407*) is found confirming that carboxyl domain deletion is tightly linked to ATMDS phenotype. Moreover, this case provides further support that EPO long term treatment seems to work well with MDS presenting ATRX mutation, but larger studies need to be conducted on MDS patient cohort to evaluate the impact of these mutations on disease evolution and prognosis.
