Here, we focus on 4H leukodystrophy, a genetic brain white matter disorder linked to <em>POLR3</em> variants with distinct clinical characteristics, which manifests with considerable clinical variability. Although 4H leukodystrophy primarily features white matter abnormalities, emerging research highlights the involvement of neuronal pathology. To address this, we analyzed mRNA and protein expression of the POLR3A and POLR3B genes throughout neuronal lineage differentiation, from the iPSC state to neuroepithelial stem cells (NES) and mature neurons. When compared across cell types, we identified elevated POLR3 gene expression in NES. However, when compared by disease status, Pol III protein levels were notably reduced in 4H patient cells. Despite these protein-level alterations, overall <em>Pol III</em> transcript levels, including tRNAs and <em>BC200</em> RNA were unchanged in 4H cells. Notably, patient-specific genetic backgrounds were found to have a significant impact on <em>POLR3A</em> expression. These results underscore the necessity of considering individual genetic backgrounds and specific developmental cell states when investigating the pathology of 4H leukodystrophy. Furthermore, our work demonstrates the utility of iPSC-based models in unraveling patient-specific disease mechanisms, thereby facilitating the development of more tailored therapeutic strategies.</div></div>","PeriodicalId":21843,"journal":{"name":"Stem cell research","volume":"88 ","pages":"Article 103805"},"PeriodicalIF":0.7,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925912","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}
