Clinical presentation of CADASIL in an Italian patient with a rare Gly528Cys exon 10 NOTCH3 gene mutation

CADASIL is an autosomal dominant arteriopathy characterised by diffuse white matter lesions and small subcortical infarcts on neuroimaging and a variable combination of recurrent cerebral ischaemic episodes, cognitive deficits, migraine with aura and psychiatric symptoms. It is caused by mutations in the NOTCH3 gene encoding a NOTCH3 receptor protein. Here, we describe the genetical, clinical, neuropsychological and neuroimaging findings in an Italian CADASIL patient with a rare mutation in exon 10 leading to a Gly528Cys substitution.
