The first assessment rounds revealed limitations and variability in the quality and completeness of genetic testing reports. To improve and harmonize reporting in NGS-based diagnostics for RND, we identified 28 topics requiring recommendations based on EQA findings. These topics were grouped into four areas: clinical information, interpretation, methodology, and reporting. A team of 31 experts with relevant expertise was formed. Using an adapted Delphi approach, two rounds of surveys were conducted to prioritize the topics. Subsequently, area-specific expert groups met to formulate recommendations, followed by a final approval round using the five-finger consensus method involving all experts. In both Delphi rounds, all topics were rated as either very important (n = 12) or important (n = 16), and all were advanced for recommendation development. Consensus recommendations were achieved for 27 of the 28 topics. These include guidance on gene panel composition and updating, addressing disease-specific limitations of NGS (e.g., repeat expansion disorders), defining minimal quality parameters, and promoting sharing of variant interpretations. Each recommendation is supported by real-world examples. Due to differences in national healthcare frameworks and policies, consensus could not be reached regarding which patients should or should not undergo NGS testing. The dissemination of these recommendations is expected to improve the quality of genetic testing and reporting in RND diagnostics, promoting harmonization across laboratories and enabling easier comparison and interpretation of genetic testing reports.","PeriodicalId":12016,"journal":{"name":"European Journal of Human Genetics","volume":"34 10","pages":"1503-1512"},"PeriodicalIF":4.6,"publicationDate":"2026-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41431-026-02198-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148600797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We re-analysed ten research cases with the visual disorder foveal hypoplasia (FH) that were previously unsolved through whole exome sequencing (WES). We used SVRare, a tool that integrates outputs from Canvas and Manta and combines these with allele frequencies and information regarding their genomic context to highlight plausible pathogenic SVs. This analysis solved 2/10 cases. Expanding this strategy, we then used SVRare in a reverse genetics approach to analyse an FH-relevant gene panel in the 100,000 Genomes Project (100KGP) rare disease cohort. This identified potentially pathogenic SVs as the cause of disease in a further 11 previously unsolved cases with phenotypes overlapping FH. In total, 11 SVs in five genes were identified as the likely cause of FH in 13 patients: SLC38A8 (1 patient), PAX6 (3), OCA2 (3), GPR143 (5) and CACNA1F (1). This analysis also identified multiple carriers of an apparently novel deletion in OCA2. However, further analysis suggested that this is, in fact, the relatively common founder variant responsible for oculocutaneous albinism (OCA) in African populations, first identified over 30 years ago. These findings show that SVRare effectively identifies deleterious SVs and illustrates the challenges in reporting SVs, including the importance of accurate and consistent reporting of such variants.","PeriodicalId":12016,"journal":{"name":"European Journal of Human Genetics","volume":"34 10","pages":"1493-1502"},"PeriodicalIF":4.6,"publicationDate":"2026-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41431-026-02190-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148535769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The newly founded GfH Commission for GCs, in collaboration with the national human genetics societies of Germany (GfH), Austria (ÖGH), and Switzerland (SGMG), the Association of German Human Geneticists (BVDH), and the Swiss Association of GCs (ASCG), conducted a multi-stage consensus-building process. The methodology involved a comparative analysis of national legal prerequisites and the application of the entrustable professional activities framework to define the interprofessional interface between GCs and medical geneticists (MGs). The resulting scope of practice (SoP) categorizes competencies across three clinical phases: pre-counselling preparation, the active counselling process, and post-analytical follow-up. The SoP distinguishes between independent GC tasks, shared clinical responsibilities, and tasks requiring MGs. Key to this model is the preservation of the legal physician-prerogative for aspects like the final medical diagnosis and test-ordering while maximizing the GC’s contribution to patient-centred communication and care. This cross-border consensus represents a landmark in European professional policy, providing a scalable blueprint for the integration of GCs into regulated medical systems.

Five newborns were diagnosed with immunodeficiencies, including two cases of adenosine deaminase (ADA)-related severe combined immunodeficiency (SCID), and three clinically significant secondary findings (idiopathic T-cell lymphopenia, DiGeorge syndrome, and transient B-cell lymphopenia). No false-negative cases were observed during follow-up. The TREC and KREC profiles were consistent with the underlying immunological diagnoses. Overall, the study demonstrates that combined SMA and SCID newborn screening is feasible, reliable, and clinically impactful, supporting its integration into public health screening programs.</p>","PeriodicalId":12016,"journal":{"name":"European Journal of Human Genetics","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148497208","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}
