The two disorders have been viewed as distinct entities, where an intermediate length expansion of 31-33 CAG-repeats is associated with sporadic ALS and a full length expansion of ≥34 CAG-repeats is associated with SCA2. We report the clinical phenotype of ATXN2-positive patients and their relatives, identified in three specialist ALS clinics, which force a reconsideration of this dichotomy. We also report the frequency of ATXN2 expansions in two large cohorts of ALS patients and in a population-matched cohort of controls. We report ten cases of familial ALS in which disease is associated with either an intermediate or a full-length ATXN2 CAG-repeat expansion. Pedigrees and patients feature additional phenotypes including parkinsonism, dementia and essential tremor (ET). We conclude that CAG-repeat expansions in ATXN2 exhibit pleiotropy and are associated with a disease spectrum that includes ALS, SCA2, and parkinsonism; to recognise this complexity we propose the new term 'ATXN2-related neurodegeneration'. We also observed sporadic ALS associated with full-length expansions. We conclude that ATXN2 CAG-repeat expansions, irrespective of length, should be considered a risk factor for ALS. Interrupted CAG-repeats were associated with an ALS phenotype in our data but we also identified ALS cases with uninterrupted expansions. Our findings have relevance for researchers, patients and families linked to CAG-repeat expansions in ATXN2.</p>","PeriodicalId":12016,"journal":{"name":"European Journal of Human Genetics","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were mapped onto implementation science framework to identify complementary theoretical strategies. Interviews with 14 genomics champions and embedded genomics experts (genetic counsellors, nephrologists, renal nurses), identified 34 barriers to incorporating genomic testing into routine care, e.g., lack of long-term multidisciplinary team support and role clarity. In total, 25 empirical implementation strategies were identified such as creating new clinical teams. Using the Consolidated Framework for Implementation Research, 10 complementary theoretical implementation strategies were identified. Our study presents a novel approach complementing empirical strategies with theoretical strategies to support nephrologists in incorporating genomic testing into routine practice. Complementary strategies can potentially address barriers and inform future studies when mainstreaming renal genomics. This process underscored the need for integrating collaborative efforts among health professionals, patients, implementation scientists and the health system to overcome identified challenges to mainstream genomic testing.

Using genotype data from 6574 individuals with associated regional Irish or British ancestry, we identified genetic communities by applying Leiden community detection. Using haplotype segments segregated by length as proxy for time, we inferred regional Irish and British demographic histories. Using a subset of Irish participants, we provide genealogical context by estimating the enrichment/depletion of surnames within the Irish genetic communities. Through patterns of haplotype sharing, we find evidence of recent population bottlenecks in Orcadian, Manx and Welsh genetic communities. We observed temporal changes in genetic affinities within and between genetic communities in Ireland and Britain. Structure in Ireland is subtler compared to neighbouring British communities, with the Irish groups sharing relatively more short haplotype segments. In addition, we detected varying degrees of genetic isolation in peripheral Irish and British genetic communities across different time periods. Further, we observe a stable migration corridor between north-east Ireland and south-west Scotland while there is a recent migration barrier between south-east and west Ireland. Genealogical analysis of surnames in Ireland reflects history-Anglo-Norman surnames are enriched in the Wexford community while Scottish and Gallowglass surnames were enriched in the Ulster community. Using these new insights into the regional demographic history of Ireland and Britain across different time periods, we hope to understand the driving forces of rare allele frequencies and disease risk association within these populations.</p>","PeriodicalId":12016,"journal":{"name":"European Journal of Human Genetics","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in the International Prospective Register of Systematic Reviews database (CRD42024532829). A comprehensive search of six databases yielded 17,292 records. After removing duplicates and screening for relevance, nine studies were included in the final analysis, conducted across diverse Western countries using both qualitative and quantitative designs. Results indicated a preference for healthcare-mediated communication, particularly through formal methods as letters, valued for their clarity and reliability. The role of family-mediated communication is nuanced, influenced by interpersonal relationship quality and the emotional burden of disclosing sensitive information. Ethical and legal considerations highlighted public support for overriding confidentiality in treatable conditions, while emphasizing respect for individual privacy and autonomy in untreatable conditions. This review underscores the importance of understanding public preferences to develop tailored communication strategies that balance professional involvement with respect for individual and familial dynamics.
