Abstract
No genetically diagnosed cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) pedigrees with venous insufficiency have been described. In a CADASIL pedigree with varicose veins, the authors have identified a novel heterozygous mutation in the 3' splice acceptor site of intron 15 of the Notch3 gene. This, based on mRNA analysis, resulted in skipping of exon 16 including eight cysteine residues of EGF-like repeats.
