Each identified micro- and macro-aberration segment for this gene is plotted with the RB1 exons identified by each gray stripe, along with the location of each RB1 probe on the tiling array (green segments), and also shown are probes from an earlier 109,000 feature single nucleotide polymorphism (SNP) platform [14], which was used in a previous study examining whole-genome landscapes of breast tumor subtypes (5 probes: red lines) (Figure 2A). Here, RB1 is linked to breast neoplasm.
