BackgroundCerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an adult-onset hereditary condition caused by mutations in the Notch3 gene. A Chinese man was studied.MethodElectronic microscopy examination of skin biopsy. The Notch3 gene was screened for mutations by polymerase chain reaction and direct DNA sequencing.ResultsElectronic microscopy showed the presence of deposits of granular osmiophilic material in dermal capillaries in the index patient. A novel heterozygous C271F in exon 6 was detected in the index patient. This heterozygous C271F mutation was also detected in the asymptomatic elder son but was not detected in the asymptomatic wife of the patient. Allele specific amplification showed that C271F was not detected in 100 normal subjects.ConclusionWe established the molecular basis of CADASIL in a Chinese man. Mutation detection assay provides a reliable method for confirming the diagnosis of CADASIL.
