Figure 1. FISH signal patterns.

Figure 1

Representative FISH signal patterns in Barrett’s esophagus with a probe set for 8q24 (MYC) [aqua], 9p21 (P16) [red], 17q12 (ERBB2) [green], and 20q13.2 (ZNF217) [yellow]. Clockwise from top left: a normal cell (2 signals of each probe), homozygous P16 loss (no red signals), hemizygous P16 loss (one red signal), single locus gain (amplification of MYC probe).
