We included participants with MRI-confirmed RSSI and at least two MRI scans during the first one-year follow-up. We assessed for lesion change by visual assessment on T2- FLAIR (blinded). We recorded demographics, vascular risk factors, SVD burden, and clinical outcomes (NIHSS, modified Rankin score [mRS], Montreal Cognitive Assessment score [MoCA]), at baseline and one-year. We report maximum axial diameters (max-ax, mm) for RSSI and lacunes (continuous and dichotomised at &lt; /≥3mm).

The main aim of our survey was to determine if there is an association between phenotypes and genotypes across the most common <em>NOTCH3</em> mutations found in CADASIL patients. We systematically searched clinical studies and genomic databases from 1996 to 2023 to first identify the most common mutations responsible for CADASIL. We found the six most common <em>NOTCH3</em> missense mutations globally were the p.R75P, p.R133C, p.R141C, p.R169C, p.R182C, and p.R544C, of which p.R133C was described to occur most often. Focusing on studies with comprehensive clinical records, our analysis further suggested that the p.R75P, p.R141C, p.R182C and p.R544C genotypes were highly congruent with the presence of white matter hyperintensities on magnetic resonance imaging (MRI), which was the most common phenotypic characteristic across all four mutations. We found the p.R141C mutation was associated with increased severity of disease. We also found the average age of onset in p.R544C carriers was more than a decade later compared to the p.R141C carriers. However, statistical analysis showed there were no overall differences between the phenotypic characteristics of the two common mutations, p.R141C and p.R544C. Geographically, China and Japan were the only two countries to report all the four common mutations vis a vis p.R75P, p.R141C, p.R182C and p.R544C.
