Not Described Variant of Notch3 Gen for Cadasil Disease.

Autosomal dominant cerebral arteriopathy with subcortical infarctions and leukoencephalopathy (CADASIL), is a genetic disease caused by mutations in the Notch3 gene. More than 170 monogenic mutations leading to the development of CADASIL have been reported. We describe a case of a patient and her family with compatible symptoms of CADASIL disease, in which a variable not yet described in the Notch3 gene was detected, that generates a probably pathogenic change in the protein.
