Patients with CADASIL experience migraines, recurrent ischemic strokes, cognitive decline, and dementia. The <jats:italic>NOTCH3<\/jats:italic> gene, which is located on chromosome 19p13.12, is one of the disease-causing genes in CADASIL. Herein, we investigate the genetic and phenotypic features in a Chinese CADASIL family with heterozygous <jats:italic>NOTCH3<\/jats:italic> mutation.<\/jats:p><jats:p><jats:bold>Methods and Results:<\/jats:bold> In the family, the proband suffered from dizziness, stroke, and cognitive deficits. Brain magnetic resonance imaging (MRI) demonstrated symmetrical white matter lesions in the temporal lobe, outer capsule, lateral ventricle, and deep brain. Whole-exome sequencing identified a known missense mutation in the proband, c.397C&amp;gt;T (p.Arg133Cys), which was identified in his son and granddaughter using Sanger sequencing. The proband\u2019s younger brother and younger sister also have a history of cognitive impairment or cerebral infarction, but do not have this genetic mutation, which may highlight the impact of lifestyle on this neurological disease.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> We identified a known CADASIL-causing mutation <jats:italic>NOTCH3<\/jats:italic> (c.397C&amp;gt;T, p.Arg133Cys) in a Chinese family. The clinical manifestations of mutation carriers in this family are highly heterogeneous, which is likely a common feature for the etiology of different mutations in CADASIL. Molecular genetic analyses are critical for accurate diagnosis, as well as the provision of genetic counselling for CADASIL.<\/jats:p>","DOI":"10.3389\/fgene.2022.943117","type":"journal-article","created":{"date-parts":[[2022,11,29]],"date-time":"2022-11-29T06:50:01Z","timestamp":1669704601000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["A heterozygous mutation in NOTCH3 in a Chinese family with CADASIL"],"prefix":"10.3389","volume":"13","author":[{"given":"Juyi","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Luo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiufang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengjie","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao","family":"Dang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aiping","family":"Deng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youzhi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheng","family":"Ding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ping","family":"Jing","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lin","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"21","DOI":"10.1007\/s11916-017-0621-0","article-title":"Recognizing CADASIL: A secondary cause of migraine with aura","volume":"21","author":"Burkett","year":"2017","journal-title":"Curr.
