Schematic representation of overlapping 3q deletions in DWM and WS patients. Extension of 3q deletions in the present three and 21 previously published subjects (only patients with molecular characterization have been included). Vertical grey and blue areas represent the proposed critical regions for DWM and WS, respectively. Horizontal bars are grouped by color according to the presence/absence of either condition, as specified in the columns on the left. Red and purple shaded bars represent patients with unknown status for WS or DWM, respectively. Vertical black lines indicate the position of FOXL2 gene (causative of BPES), and ZIC1-ZIC4 genes, as indicated. *previously described by Sudha et al. ; **previously described by Ko et al. .
