An Atypical 15q11.2 Microdeletion Not Involving SNORD116 Resulting in Prader–Willi Syndrome

Figure 3

Fluorescence in situ hybridization (FISH) and chromosomal microarray. (a). Chromosomal microarray results of proband indicating ∼132 kb deletion at 15q11.2 (red line). (b). Analysis by FISH with cloneRP11-125E1 (red signal) confirmed partial deletion at 15q11.2. Blue probe is the centromere of chromosome 15, and the green probe is the control PML probe of 15q22. FISH, fluorescence in situ hybridization.
