CADASIL
Communication of a Uruguayan family with clinical, imaging, pathological and molecular genetic definition
Abstract
Introduction: CADASIL syndrome (Cerebral Dominant Arteriopathy with Subcortical Infarcts and Leukoencephlopathy), the most common form of hereditary stroke disorder is a nonamyloid, non-atheromatous microangiopathy. Main clinical features are found in the brain. The disease may be diagnosed by clinical findings, images and genetic molecular criteria.
Methods: an anatomopathological analysis through a skin and muscle biopsy and molecular study was performed on three members of the same family diagnosed with CADASIL.
Results: clinical, paraclinical, neurological and ultrastructural skin biopsy study’s findings were consistent with CADASIL. Notch3 sequence exonal analysis (2,3,4,5,8,11,20,23) suggested heterocigotic mutations in exon 5, not previously described in literature.
Conclusions: we stress the importance of early diagnosis of this disease and the molecular definition that enables genetic counselling to all members of the family and, potentially, prenatal diagnosis of the disease.
