These are autosomal dominant disorders characterized by progressive dementia with an onset at around the fifth decade of life. We describe a family with cognitive impairment caused by a novel ITM2B p.*267Serext*11 mutation. The probands presented with cognitive impairment and cerebral infarction. MRI revealed diffuse white matter hyperintensity and microbleeds. Amyloid deposition was not observed on amyloid positron emission tomography. Our case suggests that the BRI2 mutation impacts cognition regardless of amyloid-\u03b2 accumulation.<\/jats:p>","DOI":"10.3233\/jad-230051","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T11:58:35Z","timestamp":1680609515000},"page":"403-409","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["A Novel c.800G&gt;C Variant of the\n                    <i>ITM2B<\/i>\n                    Gene in Familial Korean Dementia"],"prefix":"10.1177","volume":"93","author":[{"given":"Jee-Min","family":"Rhyu","sequence":"first","affiliation":[{"name":"Department of Neurology, Jeonbuk National University Medical School and Hospital, Jeonju, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joonhong","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, Jeonbuk National University Medical School and Hospital, Jeonju, Republic of Korea"},{"name":"Research Institute of Clinical Medicine of Jeonbuk National University -
