Although myelin degradation in the corpus callosum of Notch3 mutant mice has been previously reported [41, 42], we showed here that reduced MBP staining also occurs in the periventricular striatum, a feature that has been frequently observed in MRI scans of human SVD patients, including CADASIL patients [43, 44]. This evidence concerns the gene MBP and snowflake vitreoretinal degeneration.
