Deletion of chromosome band 13q14: a primary event in preleukemia and leukemia. 1985

R Morgan, and F Hecht

Chromosome abnormalities were analyzed in 200 consecutive patients with preleukemia and leukemia, and four patients were found with a deletion of 13q14 for an incidence of 2%. Together with data on chromosome aberrations in cancer from the literature, our results indicate clearly that deletion of band 13q14 is a nonrandom chromosome anomaly in premalignant and malignant blood disorders. Deletion of 13q14 appears specifically to constitute a primary event in the initiation of preleukemia. An additional rearrangement involving another chromosome must occur for progression of the preleukemia to acute nonlymphocytic leukemia.

D007223	Infant	A child between 1 and 23 months of age.	Infants
D007621	Karyotyping	Mapping of the KARYOTYPE of a cell.	Karyotype Analysis Methods,Analysis Method, Karyotype,Analysis Methods, Karyotype,Karyotype Analysis Method,Karyotypings,Method, Karyotype Analysis,Methods, Karyotype Analysis
D007938	Leukemia	A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011289	Preleukemia	Conditions in which the abnormalities in the peripheral blood or bone marrow represent the early manifestations of acute leukemia, but in which the changes are not of sufficient magnitude or specificity to permit a diagnosis of acute leukemia by the usual clinical criteria.	Preleukemias
D002871	Chromosome Banding	Staining of bands, or chromosome segments, allowing the precise identification of individual chromosomes or parts of chromosomes. Applications include the determination of chromosome rearrangements in malformation syndromes and cancer, the chemistry of chromosome segments, chromosome changes during evolution, and, in conjunction with cell hybridization studies, chromosome mapping.
