A, Array CGH profile of chromosome 1 (patient 1). Note the microdeletion in 1q21.1. B–E, Confirmation of the microdeletion by FISH. B, Deletion of RP11-698N18 (labeled with Spectrum green) and two normal signals of control probe CEP1 (labeled with Spectrum orange) (patient 4). C, Partial deletion of RP11-258G05 (labeled with Spectrum green) and two normal signals of control probe CEP1 (labeled with Spectrum orange) (patient 4). D, Deletion of RP11-258G05 (labeled with Spectrum green) and two normal signals of control probe RP11-5P4 located in chromosomal band 1p31.3 (labeled with Spectrum orange) (patient 7). E, Two normal signals of RP11-258G05 (labeled with Spectrum green) and of control probe RP11-5P4 (labeled with Spectrum orange) (patient 20).
