Herein, we have reported a patient presenting hallmarks of EIEE.</p><p><strong>Methods: </strong>The patient underwent clinical, radiographic, and genetic analysis. A thorough clinical examination and molecular study were conducted utilizing whole exome sequencing and Sanger sequencing.</p><p><strong>Results: </strong>Whole exome sequencing of the proband revealed a novel de novo nonsynonymous/nonsense variant (c.1468A>T; (p.Lys490Ter) in exon 6 of the <i>HCN1</i> gene. This variant may cause channel dysfunction via nonsynonymous/nonsense-mediated decay or aberrant protein, which may be associated with EIEE phenotypes.</p><p><strong>Conclusions: </strong>This evidence backs the idea that HCN1 has a vital role in brain development and lose of function can cause a range of debilitating conditions. Still, the functional characterization study of the <i>HCN1</i> variants will be the fundamental tool for a better understanding of EIEE in the near future.</p>","PeriodicalId":48566,"journal":{"name":"Molecular Syndromology","volume":"16 2","pages":"152-164"},"PeriodicalIF":0.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11961093/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143774484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
