A novel heterozygous HTRA1 mutation in an Asian family with CADASIL-like disease.

ABSTRACT:

Background

HTRA1 gene mutations are related to the pathogenesis of cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL). However, heterozygous HTRA1 mutations at specific sites can also lead to rare autosomal dominant cerebral artery disease (CADASIL-like disease). To date, 28 heterozygous mutations in the HTRA1 gene have been reported to be related to CADASIL-like diseases. Only one case of this disease was caused by a heterozygous mutation of c.497G>T in exon 2 of the HTRA1 gene.

Methods

In this case, we report on an Asian family with CADASIL-like disease caused by a heterozygous mutation of c.497G>T in exon 2 of the HTRA1 gene. The clinical and imaging characteristics of the proband were summarized, and gene mutations were
