Upon revisiting their published work on a defect in the CLIP1 gene, the authors noted that the brain MRI obtained from the affected girl (IV: 7), which was reported to be normal at that time, showed a local white matter around fornices with abnormal signal of the frontal horns' ‘focal leukoencephalopathy'. They would like to report focal leukodystrophy in the brain MRI of the patient with CLIP1 mutation as a migration role of this gene in cortical neurons (Figure 1).
