Distinct Small Vessel Disease Phenotype Linked to Monoallelic NOTCH3 Loss-of-Function Variants: Differentiation from CADASIL and Clinical Implications

By MedXY|Oct 6, 2025

Monoallelic NOTCH3 loss-of-function variants cause a subclinical small vessel disease distinct from CADASIL, with white matter changes but lower stroke risk; cardiovascular risk factors and aging exacerbate the phenotype.
