Ideograms summarising FISH results observed for each cell line using 18q, 18q11 and 18q21 paints.  

A Breast cell lines B Colorectal cell lines C Pancreatic cell lines D Melanoma cell line
E Cervical cell line.  

• All copies of chromosome 18 are shown, including apparently normal ones.
• The identity of the translocation partner is indicated for each derivative.
• '?' indicates that the translocation partner is unknown.
• The size of each translocation partner is approximate.
• Filled black triangles indicate approximate position of breakpoints.
• Unfilled triangles indicate breakpoints that were not counted in our breakpoint survey (see Alsop et al, 2005) as they either appeared balanced, or the (derivative) chromosome had been duplicated.
