title: Cytogenetics of chronic myeloproliferative disorders and related myelodysplastic syndromes.
abstract: The only MPD associated with any specific chromosome anomaly is CML, which is linked with t(9;22)(q34;q11.2) or a variant of this anomaly. An association exists for del(13)(q12q14) and CIMF; t(5;12)(q33;p13) and CEL; and del(20q11), +8, and +9 and PV, but these anomalies can be seen in various hematologic malignancies. The most common chromosomal anomalies among MPD in order of frequency are t(9;22)(q34;q11.2), -Y, +8, +9, -7, del(20) (q11q13), del(13)(q12q14), del(5)(q13q33), and del(12)(p12). FISH techniques are useful for MPD to study inadequate bone marrow or blood specimens and to monitor disease status among patients with known chromosome anomalies, but they are not more sensitive than conventional chromosome studies.
