Figure 6.

Frequency of SD cells for ARSA in samples from control individuals and from patients with DGS/VCFS. In frame (c) the frequency of SD cells in each individual sample was separated into two sub-categories: cells in which the ARSA signal of the deletion-carrying homologue shows a singlet (S-signal, open bar) and those in which the ARSA signal of the deletion-carrying chromosome reveals a doublet (D-signal, solid bar). The mean frequencies and standard deviations for each group of samples are also given (last bar(s) in each frame). The P value in frame (a) represents the significance of the difference between the values in frames (a) and (b); the P value in frame (c) shows the significance of the difference between the S and D values for the ARSA signal of the deletion-carrying homologue within the total ARSA SD cell population.
