Figure 2: The results of MLPA and array CGH analysis in two probands with 15q11.2 microdeletion. I. Chromosomal organization of the 15q11.2 region. II. Visualization of MLPA results showing the deletion of fragments complementary to probes for the particular loci (NIPA1, NIPA2, CYFIP1, TUBGCP5) and array CGH confirming the presence of the deletion in 15q11.2 region.
