Myelodysplastic syndromes (MDS) are clonal hematologic stem cell disorders with an as yet unknown molecular pathology. Genetic instability has been proposed as a cause of MDS. Mutations in the NBS1 gene, whose product nibrin (p95) is involved in DNA damage repair and cell-cycle control, might be associated with an elevated predisposition to the development of MDS. The aim of the study was to examine truncating 5 bp deletion (657del5), the most frequent NBS1 gene mutation in Slavic populations, in MDS patients. Among 71 MDS patients, we found one case that was heterozygous for the NBS1 657del5 mutation. To the best of our knowledge, this is the first report of a NBS1 mutation in MDS.
