FISH characterization of deleted marker. a FISH analysis with the specific probe for Xp11.1-q11.1 alpha-satellite (DXZ1, red signals) on the normal chromosome X and the deleted marker (arrow). b FISH analysis with the probe for common telomeric sequences (TTAGGG, red signals) on all chromosomes. The grey and the white arrows, indicate the deleted marker and the acentric fragment respectively. c FISH analysis with the specific probe for Xp/Yp telomere (DXYS129, red signals) on the normal chromosome X and the entire marker. The arrow indicates the possible breaking point. d FISH analysis with the specific probe for Xp/Yp telomere (DXYS129, red signals) on the normal chromosome X and the deleted marker (arrow). e Schematic representation of deleted marker structure
