Comparison of all reported cases of deletion and duplication of 9p for which microarray analysis was performed. Shaded boxes represent the 2 Mb terminally deleted region (green), the proposed critical region for Deletion 9p Syndrome (blue), and the region associated with Duplication 9p Syndrome (red). Group 1 includes cases with deletions below 2 Mb, Group 2 comprises cases with deletions covering the 2 Mb terminal region, and Group 3 includes cases with deletions encompassing the proposed critical region for Deletion 9p Syndrome (Group 3).
