Progress in the Genetics of Myelodysplastic Syndromes with a Latin American Perspective

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematological malignancies characterized by ineffective hematopoiesis, resulting in cytopenias, morphologic dysplasia in hematopoietic lineages, and a variable risk of progression to acute myeloid leukemia. Significant advances in the understanding of MDS have been made in recent years, largely due to the implementation of molecular tools. Latin America is a highly diverse region, both ethnically and racially, and often faces resource limitations that challenge the broad applicability of recent advances in MDS. In this review, we discuss the key genes implicated in the pathogenesis and classification of MDS, and their relevance to diagnosis, prognosis, and potential therapeutic targets. We also explore the challenges associated with the identification of germline predisposition to MDS in Latin America and discuss the current availability and limitations of molecular diagnostic tools in the region.
