Over 180 variants have been associated with the disease, with a wide spectrum of severity and clinical manifestations. Previous attempts at genotype-phenotype correlations have been hampered by the small numbers of cases that have been published for many of the variants. We sought to determine whether genotype-phenotype correlations could be discerned from available information.</p><p><strong>Methods: </strong>We compiled a list of variants in <i>GFAP</i> for which 7 or more unrelated cases had been either published or identified through an ongoing natural history study and other sources (with a closing date of July 27, 2024). For each of these cases, we tabulated age at onset, age at death (or last contact), and sex. We used a Kruskal-Wallis test to evaluate statistical differences in age at onset in relation to variant. Differences in survival across variants were studied using Kaplan-Meier curves.</p><p><strong>Results: </strong>Fourteen variants met our criteria for detailed analysis (10 with 7 or more unrelated cases and 4 additional variants involving 2 of the most commonly affected amino acids, R79 and R239) derived from a total of 231 cases. The variants seem to fall into 3 distinct groups-some with consistent early onsets (N77S, R79C and R79L, and most of the R239s), some with consistent late onsets (R70W and N386S), and some with more variable onsets (R416W). Pairwise comparison results found that R239H was associated with significantly earlier onsets than R239C. We found similar groupings for survival. Finally, we evaluated sex as a potential modifying factor for either age at onset or survival but found no significant association.</p><p><strong>Discussion: </strong>Genotype-phenotype correlations do exist in Alexander disease, at least for a limited number of GFAP variants for which sufficient numbers of individual cases can be identified to allow valid statistical analysis.</p>","PeriodicalId":48613,"journal":{"name":"Neurology-Genetics","volume":"11 3","pages":"e200270"},"PeriodicalIF":3.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12166557/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variable number tandem repeats (VNTRs) are important polymorphic components of the genome; however, they have been previously overlooked because of their complex genotyping. New software can now determine differing lengths of VNTRs; however, this has not been tested in a large case-control population.</p><p><strong>Methods: </strong>We used VNTRseek to genotype over 200,000 tandem repeats in 9,501 cases and controls from the Alzheimer's Disease Sequencing Project. We first identified limiting factors of this analysis and then examined the association of VNTRs with AD diagnosis in a subset of non-Hispanic White participants.</p><p><strong>Results: </strong>We found that VNTRs were highly associated with areas of the genome with a high number of previously identified variants. From our case-control analysis, we identified 9 VNTRs with a repeat allele length associated with LOAD including VNTRs on DSC3, NR2E3, CCNY, PKP4, GRAP, and MAP6.</p><p><strong>Discussion: </strong>We were able to show the feasibility of this new type of analysis in large-scale whole-genome sequencing data and identify promising VNTRs that are associated with LOAD.</p>","PeriodicalId":48613,"journal":{"name":"Neurology-Genetics","volume":"11 2","pages":"e200241"},"PeriodicalIF":3.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11839231/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143469632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
