This report highlights a novel heterozygous missense mutation in exon 30 of the DNMT1 gene that was detected in a middle-aged lady who presented with early-onset dementia on a background of long-standing psychosis with depression and neuroleptic sensitivity. This case expands the phenotypic spectrum associated with DNMT1 mutations and highlights the potential value of genetic testing in evaluating atypical neuropsychiatric presentations. The phenotypic complexity highlights the critical need for further research to elucidate the mechanistic links between DNMT1 mutations and neuropsychiatric disease, paving the way for targeted therapeutic interventions.</p>","PeriodicalId":20734,"journal":{"name":"Psychiatric Genetics","volume":" ","pages":"136-141"},"PeriodicalIF":1.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144592038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
