PG - 292-8 AB - A 49-year-old woman patient with atypical myelodysplastic syndrome (MDS) showing a der(3)t(3;12)(q21;p13), and der(12)t(3;12)(q21;p13)inv(3)(q21q26) as an acquired chromosomal abnormality in the bone marrow is described. The chromosomal breakpoints of the presented complex aberration with combination of the inv(3)(q21q26) and t(3;12)(q21;p13) were defined by fluorescence in situ hybridization (FISH) with yeast artificial chromosomes (YACs). The inv(3) is a relatively frequent chromosomal rearrangement in patients with myeloid malignancies and dysmegakaryopoiesis and t(3;12)(q26;p13) has also been reported as a recurrent abnormality in MDS and in blast crisis of chronic myelogenous leukemia (CML). Whereas the t(3;12), inv(3), and t(3;3) are associated with a very poor prognosis, our patient surprisingly had a mild clinical course.
