Introduction

Newborn bloodspot screening (NBS) is freely and universally available to babies born in Australia, with nearly 300 000 newborns screened each year. The NBS programme screens for approximately 30 conditions; however, there are hundreds of childhood conditions that could be treated if identified earlier and asymptomatically. Contemporary screening platforms have relied on mass spectrometry-based technologies, limiting surveillance to conditions with validated biomarkers detectable within the neonatal period. Advancements in metabolic techniques and genomics have expanded the range of conditions that could be detected. The NewbornsInSA research study will develop, validate and evaluate a novel multi-omic model of newborn screening, integrating metabolomic and genomic newborn screening as complementary methodologies.

Methods

Parents can opt in to additional NBS through NewbornsInSA during pregnancy or shortly after birth. One thousand prospectively recruited families will be offered genomic NBS by whole-genome sequencing, including analysis of a virtual gene panel of over 600 genes, and concurrent metabolomic screening. Clinically actionable pathogenic or likely pathogenic genetic variants will be reported to parents and whole genome sequencing data will be available on request for diagnostic reanalysis, if required later in life.

Acceptability of the NewbornsInSA programme will be evaluated through stakeholder engagement activities with healthcare professionals, members of the public and patient advocacy groups. Family experiences will be assessed using online surveys. The diagnostic yield, accuracy and the costs and consequences of the multi-omic NBS model will be assessed by comparison to standard-of-care NBS.

NewbornsInSA will investigate the acceptability, feasibility and cost-effectiveness of a multi-omic newborn screening model in a prospectively recruited South Australian population. We hypothesise that this approach will increase the number of conditions identified, reduce the time to diagnosis and facilitate earlier care with better outcomes for newborns with genetic conditions.

Ethics and dissemination

This research study has been ethically approved by the Women’s and Children’s Health Network Human Research Ethics Committee (2022/HRE00258 and 2023/HRE00236). Findings will be disseminated through peer-reviewed publication and conferences.

Matrix-directed therapy losartan to identify the effect on the bone resorption marker carboxy-terminal crosslink of type I collagen telopeptide (CTX) in older adolescents and adults with osteogenesis imperfecta recruited from secondary care sites: the 'MO

Por: Haji Sadeghi · M. · Cohen · J. · Williams · B. · Wilkinson · A. · Sumpter · S. · Simms · L. · Huang · C. · Pugh · K. · Heath · C. · Sangiorgi · L. · Gurioli · F. · Gnoli · M. · Moroni · A. · Leopardi · M. P. · Del Coco · C. · Bishop · N.
Introduction

Osteogenesis imperfecta (OI) is the most common inherited cause of bone fragility (approximately 1 in 16 000). People with OI suffer bone fragility causing fractures, pain and deformity; sarcopenia causing fatigue and poor endurance; aortic root dilatation and hearing loss. No drug currently has market authorisation to treat OI in Europe. Current standard-of-care is multidisciplinary, with pharmacological interventions—primarily bisphosphonates—directed at increasing bone mass; however, such interventions are of equivocal efficacy. The structural damage that can accumulate as a result of repeated fractures over time may not be reversible. The lack of a treatment with clearly defined efficacy in terms of reducing fracture frequency or the sarcopenia, that is increasingly recognised in this condition, leads to the consideration of alternatives based on what is known about the molecular pathophysiology of the condition. For reasons that are currently unclear, transforming growth factor beta (TGFβ) pathway signalling is increased in OI, and both studies in mouse models and more recently also in humans suggest that reducing TGFβ pathway signalling could be of benefit in OI. This demonstrator project tests the hypothesis that losartan, an antihypertensive agent known to reduce circulating TGFβ, will reduce bone turnover and bone loss and have a positive effect on muscle function and quality of life in adults and older adolescents with OI.

Methods and analysis

This is a phase 2/pilot, open-label, dose-escalating study. This study aims to identify the effective dose for losartan in this population to inform the design of a pivotal phase III study. The study aims to recruit 30 adolescents and adults aged 16 years and above with OI across secondary care study sites in the UK and Italy. Participants will be recruited from the patient populations attending for treatment of OI at the participating hospital sites or referred by clinicians at the Participant Identification Centres (PIC sites). Participants will be randomised to one of three ‘final doses’—25, 50 or 75 mg losartan once daily. All participants will start on 25 mg once daily. Those assigned to higher ‘final doses’ will increase in 25 mg once daily increments on day 8 and day 15 following safety assessments. The primary outcome measures are to establish the effective dose of losartan in OI patients, based on maximal reduction in the bone resorption marker carboxy-terminal crosslink of type I collagen telopeptide (CTX) over the 24-week period of the study.

Secondary outcome measures are to determine the changes in proxy efficacy outcomes for bone (turnover, mass, architecture and strength) using blood tests, high-resolution peripheral quantitative CT (HRpQCT), dual-energy X-ray absorptiometry (DXA) and muscle (strength) using the ‘Timed Up and Go’ test. In addition, the changes in quality of life, including pain and fatigue, will be evaluated by using a disease-specific tool (OI-QOL) and a validated generic tool (EQ-5D-5L-VAS).

Ethics and dissemination

In the UK, the study protocol and amendments have been approved by the London Bridge Research Ethics Committee (REC reference: 23/LO/015) and by the Medicines and Healthcare products Regulatory Agency (MHRA). In Italy, the study protocol and amendments have been approved by the Italian and European ethics and regulatory authorities (Clinical Trials Information System European Union (CTIS EU) portal according to EU Regulation 536/2014). Final version of study protocol: Version 3.2, 05.03.2025. Final results will be disseminated in peer-reviewed journals through local OI, orthopaedic and other relevant clinical networks and at national and international meetings. Sheffield Children’s National Health Service Foundation Trust (UK) and Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) Istituto Ortopedico Rizzoli (Italy) are the joint study sponsors.

Por: Voi · V. · Giordano · N. · Sciannameo · V. · Sciarrone · A. · Sbaiz · L. · Barberis · M. · Curcio · C. · Irrera · M. A. · Roetto · A. · Piga · A. · Giachino · D. F. · Mandrile · G.
Objectives

To analyse demographic trends and decision-making patterns regarding prenatal diagnosis (PND) in couples at risk for hereditary haemoglobinopathies at the Thalassemia and Rare Haematological Disease Centre in Turin over a 40-year period.

Design

Retrospective observational study analysing demographic and clinical data from 1983 to 2023.

Setting

Tertiary care genetic service Centre in Orbassano (TO), Northern Italy.

Participants

Couples seeking genetic counselling and PND for hereditary haemoglobinopathies. Selection criteria included couples at risk of having children affected by β-thalassaemia major or Sickle Cell Disease (SCD).

Main outcome measures

Primary outcomes included acceptance rates of PND and pregnancy termination (TOP). Variables analysed included couples’ age at first consultation, age at first PND, birthplace, employment status, specific haemoglobinopathy risk and number of pregnancies.

Results

The analysis identified three main factors influencing PND and TOP decisions: nationality, type of haemoglobinopathy risk and number of previous pregnancies. Age showed no significant correlation with decision-making patterns. The impact of education level and employment status could not be definitively determined due to unavailable or unfit data.

Conclusions

The 40-year analysis of prenatal diagnosis for haemoglobinopathies in Turin shows evolving trends influenced by immigration patterns, improved medical treatments and cultural factors, leading to increased acceptance of affected pregnancies in recent years, particularly after 2015, due to better disease management and comprehensive healthcare support. This comprehensive analysis of our centre’s experience provides valuable insights that can serve as a model for similar institutions worldwide in supporting couples through carrier screening and PND processes.

Attitudes, awareness and experience of Italian women undergoing non-invasive prenatal testing (NIPT): a nationwide cross-sectional study

Por: Godino · L. · Nardi · E. · Lanzoni · G. · Pompilii · E. · Calabrese · S. · Bertonazzi · B. · Carrara · M. · Gazineo · D. · Turchetti · D.
Objectives

Despite the increasing availability of non-invasive prenatal testing (NIPT), women’s experiences and motivations remain largely unknown. The use of NIPT is increasing in Italy; however, its organisation and access paths vary considerably. Women may undergo testing in either public or private facilities, where differences in pretest information, testing procedures and result communication may influence their experience. This study aims to investigate the attitudes, awareness and experiences of Italian women undergoing NIPT.

Design

A cross-sectional anonymous online survey was conducted via social media in the period March–August 2023.

Setting

This nationwide study was conducted in Italy.

Participants

Women over 18 years old who had undergone NIPT were included.

Results

Responders were 4154 women from every part of Italy. Most participants perceived the information provided during pre-NIPT counselling as extremely/very clear (68.2%) and helpful (72.5%), with higher proportions observed when counselling was delivered by geneticists. The mean knowledge score was 12.3 (range: 0–15) and was statistically higher for women with higher education level and prior NIPT experience. Half of the women reported no change in their perceived risk of having a child with chromosomal abnormalities after pre-NIPT counselling, and risk perception reduction was associated with lower knowledge scores. Pretest negative emotions were common (54.9%) and influenced by testing context, information sources and reasons for testing. Most women reported a positive impact from results (92.7%), shaped by information delivery made and prior knowledge. Regret was rare (3.0%) and linked to reasons and perceived risk changes. Overall, satisfaction was high (97.3%), particularly among those prioritising informed decision-making.

Conclusions

Improving personalised counselling and education throughout the NIPT journey seems crucial to minimise negative emotional impacts, highlighting the need for well-trained healthcare professionals.

Introduction

In the last 60 years, newborn bloodspot screening (NBS) has expanded as a public health intervention from a single severe childhood genetic disease (SCGD) to up to as many as 80 SCGD and testing of ~40 million newborns/year worldwide. However, the gap between current NBS and its potential to increase the efficiency, effectiveness and global equity of healthcare delivery for SCGD is large and rapidly growing. There are now effective therapeutic interventions—drugs, diets, devices and surgeries—for up to 2000 SCGD. Since almost all SCGD can be identified by bloodspot genome sequencing, it has been a longstanding goal to supplement current NBS with genome sequencing-based NBS (gNBS) for all eligible SCGD. We recently described a novel gNBS platform (named Begin Newborn Genome Sequencing (BeginNGS)) with the potential to overcome several major challenges to gNBS (cost, scalability, false positives and an unprepared healthcare workforce). A pilot clinical trial of BeginNGS for 412 SCGD in a level IV neonatal intensive care unit (NICU) had a true positive rate of 4.2%, sensitivity of 83%, positive predictive value of 100% and clinical utility rate of 4.2%, indicating readiness of the platform for use in a powered, multicentre study.

Methods and analysis

The BeginNGS study is a single group, international, multicentre, adaptive clinical trial to compare utility, acceptability, feasibility and cost-effectiveness of BeginNGS gNBS (experimental intervention) with standard NBS (control). A minimum of 10 000 neonates (aged 50 000 US children per year.

Ethics and dissemination

This study was approved by the WCG Clinical institutional review board on 14 February 2024, and the most recent amendment approved on 7 October 2025 (approval number 20235517). Study findings will be shared through research consortium workshops, national and international conferences, community presentations and peer-reviewed journals.

Background

The prevalence of depression and mood disorders has been steadily rising in Australian youth, with a concomitant increase in antidepressant pharmacotherapy prescription rates. Yet, the tolerability and efficacy of antidepressant drugs in youth remain poor. Pharmacogenetic (PGx) testing, or the personalised and guided treatment of medication based on genetic data, has been suggested to improve the effectiveness and tolerability of antidepressants. However, limited studies have evaluated the utility of antidepressant PGx-guided treatment in adolescent and young adult populations. Thus, this pilot randomised controlled trial (RCT), the GENE-YD Study, will evaluate the feasibility for a large-scale RCT assessing the effect of PGx-guided antidepressant prescription vs treatment as usual in youth with major depressive disorder (MDD).

Methods and analysis

Eighty young people between 16 and 24 years of age and in the early stages of pharmacotherapy treatment for MDD will be recruited. Following initial screening, participants will be randomised on a 1:1 ratio to either the intervention or control study group. Participants in the intervention condition will have their treatment tailored based on their PGx profile. Participants randomised into the control group will have their prescription based on current best practice recommendations, or treatment as usual. Individuals will be assessed at drug prescription baseline and again 6 and 12 weeks following drug prescription. The primary outcome of the study will be to evaluate the feasibility and acceptability of the GENE-YD protocol. Specifically, this study will explore participation recruitment strategies and attrition to the study protocols to guide the recruitment processes of a large-scale RCT, along with participating satisfaction in overall study protocols. Secondary outcomes will inform the utility and variability of specific measures (eg, depression rating scales, quality of life measures and medication adherence scales) that may be scaled up for use in a future full-scale trial.

Ethics and dissemination

Ethics approval was granted by the Department of Health, Western Australia’s Human Research Ethics Committee (RGS0000006822) and recognised by the University of Western Australia’s Human Research Ethics Committee (2024/ET000685). All participants will be required to provide written informed consent. Results will be published in international peer-reviewed journals.

Introduction

International pilot projects focusing on next-generation sequencing in newborn screening (NBS), that is, genomic NBS (gNBS), have been established thanks to continuous therapeutic progress and the massive development of new genetic technologies with rapidly decreasing costs. Given the highly encouraging results of the French SeDeN project regarding anticipated acceptability among professionals and parents, it is now appropriate to launch a similar pilot project in France, in collaboration with other international initiatives under the International Consortium on Newborn Sequencing framework.

Methods and analysis

PERIGENOMED is a large-scale project designed to provide the first concrete evidence on the relevance of gNBS in France. It includes two clinical trials. We present here the design chosen for the first clinical trial (PERIGENOMED-CLINICS 1). PERIGENOMED-CLINICS 1 aims to assess the feasibility, real-world acceptability, psychosocial impact and organisational pathways of panel-based genomic newborn screening in France, involving 2500 participants. Solo-GS targeting two lists of gene–disease dyads responsible for treatable (list 1; 400 genes, 171 diseases/group of diseases) or actionable (list 2 optional; 407 genes, 218 diseases/group of diseases) rare and severe early-onset diseases will be proposed in five health institutions. Ancillary social and impact studies will also be included.

Ethics and dissemination

All study procedures have been reviewed and approved by relevant French ethics committees and regulatory authorities (CPP Est II-2024-A02224-43, 1 January 2025). Results of the project will be disseminated through peer-reviewed publications, national and international conferences, and public engagement initiatives, in coordination with stakeholders.

Introduction

Rare diseases (RD) are collectively common and often genetic. Families value and can benefit from precise molecular diagnoses. Prolonged diagnostic odysseys exacerbate the burden of RD on patients, families and the healthcare system. Genome sequencing (GS) is a near-comprehensive test for genetic RD, but existing care models—where consultation with a medical geneticist is a prerequisite for testing—predate GS and may limit access or delay diagnosis. Evidence is needed to guide the optimal positioning of GS in care pathways. While initiating GS prior to geneticist consultation has been trialled in acute care settings, there are no data to inform the utility of this approach in outpatient care, where most patients with RD seek genetics services. We aim to evaluate the diagnostic yield, time to diagnosis, clinical and personal utility and incremental cost-effectiveness of GS initiated at the time of referral triage (pre-geneticist evaluation) compared with standard of care.

Methods and analysis

200 paediatric patients referred to one of two large genetics centres in Ontario, Canada, for suspected genetic RD will be randomised into a 1:1 ratio to the intervention (GS first) or standard of care (geneticist first) arm. An unblinded, permuted block randomisation design will be used, stratified within each recruitment site by phenotype and prior genetic testing. The primary outcome measure is time to genetic diagnosis or to cessation of active follow-up. Survival analysis will be used to analyse time-to-event data. Additional measures will include patient-reported and family-reported measures of satisfaction, understanding and perceived test utility, clinician-reported measures of perceived test utility and management impact, and healthcare system utilisation and costs.

Ethics and dissemination

This study was approved by Clinical Trials Ontario. Results will be disseminated, at minimum, via peer-reviewed journals, professional conferences and internal reports to funding bodies. Efforts will be made to share aggregated study results with participants and their families.

Trial registration number

NCT06935019.

Genomic literacy in nursing: a systematic scoping review of the literature

Por: Dante · A. · Masotta · V. · Paoli · I. · Caponnetto · V. · Caples · M. · Laaksonen · M. · Kamensek · T. · Petrucci · C. · Lancia · L.
Objective

To map the available evidence on genomic literacy among clinical nurses, nursing students and nursing faculty.

Design

Systematic scoping review.

Data sources

A comprehensive search was conducted in PubMed, CINAHL, Scopus, Web of Science, Academic Search Premier and OpenGrey. The review included studies published in English from 1 January 2001 to 28 May 2025.

Eligibility criteria for selecting studies

Studies that referenced ‘genomic literacy’ in health-related or educational contexts and focused on nurses, nursing students or nursing faculty were included. Articles had to provide data on study design, population, setting, data collection tools and outcomes related to genomic literacy.

Data extraction and synthesis

Two independent reviewers extracted and summarised data on study characteristics, including publication year, country, setting, aims, methods, population, assessment tools, outcomes and educational interventions. Findings were synthesised descriptively.

Results

Of 1534 studies identified, 63 met the inclusion criteria. Most were observational (69.8%) and conducted in the USA (41.3%), focusing on clinical nurses (50.8%) in educational (47.6%) or clinical (46.0%) settings. Genomic literacy was predominantly assessed using ad hoc tools (46.0%) or the Genomic Nursing Concept Inventory, revealing low literacy levels. Mean scores ranged from 5.66 to 16.21 out of 31 (18.3%–52.3% correct answers). Educational interventions demonstrated effectiveness in improving genomic knowledge.

Conclusions

Genomic literacy among nurses, students and faculty remains low, with notable heterogeneity across countries. Many studies used non-standardised assessment tools with uncertain reliability and genomic literacy among nursing faculty remains underexplored. Educational interventions show promise in enhancing genomic literacy
