title: Del(3)(p13) in B-prolymphocytic leukemia--a new nonrandom chromosomal aberration possibly related to the c-ras oncogene.
abstract: Cytogenetic analysis was performed on the leukemic cells from two patients with B-prolymphocytic leukemia. Both patients had del(3)(p13) chromosomal abnormality, as well as other clonal aberrations. Del(3p) was previously reported in one case of B-cell prolymphocytic leukemia, and is known to be a specific aberration in small-cell carcinoma of the lung. In B-cell prolymphocytic leukemia, as in other B-lymphocytic leukemias/lymphomas, the karyotype often involves chromosomes #3, #6, #11, and #12. All of these chromosomes are suggested sites for the c-ras oncogene family.
