Karyotype
|
modal number = 62; range = 55 to 64; hypertriploid. Twenty-three marker chromosomes were common to most cells: der(2)t(2;18)(p25;p11), del(3)(q21), der(10)t(10;13)(p15;q11), der(7)t(7;7)(q36;p13), del(7)(q11),; der(8)t(7;8)(p13;p23), del(8)(p12), del(9)(p22), del(9)(p13), del(11)(p12), del(12)(p12), t(13q18q) and 11 others. The del(9)(p13) was paired; normal N13 was absent. N15 had three copies and N22 had four copies.; A total of 65 marker chromosomes were detected in 38 metaphases examined.; A minor subline that occurred in about 16% of the cells was characterized by the presence of del(M5)(7p11) replacing M5, by the single N17 (instead of paired N17) and by the presence of an additional M42.
