Karyotype from patient 7 shows the complex karyotype, -4 5 , X Y , d e l ( 1 ) ( p 2 2 ) , ;k1 d e l ( 1 ) ( q 1 2 ) ;k4 2 , d e l ( 3 ) ( p 1 1 ) , ;k2 5 , ;k2 7 , d e l ( 1 2 ) ( p 1 1 ) , ;k2 1 6 , ;k2 1 7 , ;k2 1 7 , ;k2 2 0 , ;k1 m a r 1 , ;k1mar2,;k1mar3. Arrows show chromosomes with structural aberrations. Open circles (;pe) indicate the locations of the ABL oncogene detected by FISH from the same Carnoy's solution. Two signals were located on two homologues of chromosome 9, one on derivative chromosome 1, and one on a marker chromosome. Mars corresponds to marker chromosomes.
