Figure 1From: Microdeletion syndromes disclose replication timing alterations of genes unrelated to the missing DNA Cells from a patient with DGS/VCFS, following two-color FISH with TUPLE1 (red) and ARSA (green). Right, a metaphase-spread with the normal chromosome 22, identified by double labeling (red and green signals) and the deletion-carrying one, distinguished by the absence of the red signal; left, an interphase cell exemplifying two ARSA (green) signals and a single TUPLE1 (red) signal. The green signal that is closer to the red was assumed to belong to the normal homologue, while the more distant one to the deletion-carrying homologue.Back to article page
