Presumptive karyotypic evidence of myelodysplastic syndrome*
Type | Cytogenetic abnormalities |
---|---|
Balanced | t(11;16)(q23;p13.3), t(3;21)(q26.2;q22.1), t(1;3)(p36.3;q21.2), t(2;11)(p21;q23), inv(3)(q21q26.2), t(6;9)(p23;q34) |
Unbalanced | −7 or del(7q), −5 or del(5q), i(17q) or t(17p), −13 or del(13q), del(11q), del(12p) or t(12p), del(9q), idic(X)(q13) |
These cytogenetic abnormalities can be used as presumptive evidence of myelodysplastic syndrome in the setting of persistent cytopenias of undertermined etiology without definite morphologic dysplasia
