title: [CADASIL: brief report on a family with a new p.G296C mutation in exon 6 of the Notch-3 gene].
abstract: BACKGROUND
  CADASIL is a dominant autosomal inborn systemic arteriopathy, whose genetic anomaly is located in the Notch-3 gene of chromosome 19. It is clinically characterised by migraine with aura, recurrent stroke and cognitive deterioration, and is one of the causes of strokes among the young.
  
  
  METHODS
  The propositus was a 57-year-old male who presented a clinical picture of dysarthria, loss of strength in the left extremities and alterations affecting balance with dysmetry in the left extremities, related with an acute ischaemic stroke in the cerebellar peduncle. An ultrastructural study of a biopsy specimen of the skin revealed the electron-dense deposits that characterise CADASIL. The genetic analysis identified a new mutation for this disease in codon 296 of exon 6 in the Notch-3 gene that produces a change of amino acid, from glycine to cysteine in protein (p.G296C).
  
  
  CONCLUSIONS
  This communication reports the case of a family with CADASIL that was a carrier of a new p.G296C mutation located in exon 6 of the Notch-3 gene.
