SNP array analysis of both patients. A gain in copy number in the 15q11q13 region of patient 1 (left) and patient 2 (right). The orange box shows the location of the copy number gain on chromosome 15 in patient 1, and the blue box shows the location of the copy number gain on chromosome 15 in patient 2. The copy number was beyond the maximum limit of the software (4×). The values on the X-axis represent the log2 ratios for the patients
