- Abstract
Background: Population-based expanded carrier screening (ECS) involves screening for multiple recessive diseases offered to all couples considering a pregnancy or during pregnancy. Previous research indicates that in some countries primary care professionals are perceived as suitable providers for ECS. However, little is known about their perspectives. We therefore aimed to explore primary care professionals' views on population-based ECS., Methods: Four online focus groups with 14 general practitioners (GPs) and 16 community midwives were conducted in the Netherlands., Results: Our findings highlight various perspectives on the desirability of population-based ECS. Participants agreed that ECS could enhance reproductive autonomy and thereby prevent suffering of the child and/or parents. However, they also raised several ethical, societal, and psychological concerns, including a tendency towards a perfect society, stigmatization, unequal access to screening and negative psychosocial consequences. Participants believed that provision of population-based ECS would be feasible if prerequisites regarding training and reimbursement for providers would be fulfilled. most GPs considered themselves less suitable or capable of providing ECS, in contrast to midwives who did consider themselves suitable. Nevertheless, participants believed that, if implemented, ECS should be offered in primary care or by public health services rather than as hospital-based specialized care, because they believed a primary care ECS offer increases access in terms of time and location., Conclusions: While participants believed that an ECS offer would be feasible, they questioned its desirability and priority. Studies on the desirability and feasibility of population-based ECS offered in primary care or public health settings are needed., (© The Author(s) 2023. Published by Oxford University Press.)

- Abstract
Expansion of newborn bloodspot screening (NBS) can increase health gain for more children but also increases the number of false-positive and uncertain results. The impact of abnormal and inconclusive NBS results on parental well-being and healthcare utilization was investigated. A questionnaire was sent to Dutch parents receiving an abnormal or inconclusive NBS result five weeks (T1) and four months (T2) post-NBS and compared to parents with a normal result (controls). In total, 35 true-positive (TP), 20 false-positive (FP), and 57 inconclusive (IC) participants and 268 controls filled out T1; 19 TP, 14 FP, 27 IC, and 116 controls filled out T2. Participants showed positive attitudes towards NBS. FP participants more often considered NBS less reliable. TP and FP participants experienced more negative emotions regarding the test result compared to controls at both T1 and T2, and IC only at T1. Parent-reported child vulnerability and perceptions of the newborn's health status and of parenthood showed no differences. TP and FP participants reported more healthcare utilization at T1, and mainly TP at T2. TP and IC participants showed more emergency department visits at T1. The findings can be used to improve NBS programs and optimize support for families with various NBS results.

- Abstract
Aims: In patients with catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare inherited arrhythmia syndrome, arrhythmic events can be prevented by medication and lifestyle recommendations. In patients who experience breakthrough arrhythmic events, non-adherence plays an essential role. We aimed to investigate the incidence and potential reasons for non-adherence to medication and lifestyle recommendations in a large, international cohort of patients with CPVT., Methods and Results: An online multilingual survey was shared with CPVT patients worldwide by their cardiologists, through peer-recruitment, and on social media from November 2022 until July 2023. Self-reported non-adherence was measured using the validated Medication Adherence Rating Scale (MARS) and a newly developed questionnaire about lifestyle. Additionally, validated questionnaires were used to assess potential reasons for medication non-adherence. Two-hundred-and-eighteen patients completed the survey, of whom 200 (92%) were prescribed medication [122 (61%) female; median age 33.5 years (interquartile range: 22-50)]. One-hundred-and-three (52%) were prescribed beta-blocker and flecainide, 85 (43%) beta-blocker, and 11 (6%) flecainide. Thirty-four (17%) patients experienced a syncope, aborted cardiac arrest or appropriate implantable cardioverter defibrillator shock after diagnosis. Nineteen (13.4%) patients were exercising more than recommended. Thirty (15%) patients were non-adherent to medication. Female sex [odds ratio (OR) 3.7, 95% confidence interval (CI) 1.3-12.0, P = 0.019], flecainide monotherapy compared to combination therapy (OR 6.8, 95% CI 1.6-31.0, P = 0.010), and a higher agreement with statements regarding concerns about CPVT medication (OR 1.2, 95% CI 1.1-1.3, P < 0.001) were independently associated with non-adherence., Conclusion: The significant rate of non-adherence associated with concerns regarding CPVT-related medication, emphasizes the potential for improving therapy adherence by targeted patient education., Competing Interests: Conflict of interest: A.A.W. is a member of the scientific advisor board of ARMGO (unpaid) and a member of the scientific advisor board of Thryvv therapeutics (unpaid).

- Abstract
In inherited and familial cardiovascular diseases (CVDs), relatives without current symptoms can still be at risk for early and preventable cardiovascular events. One way to help people evaluate their potential risk of CVD is through a risk-assessment tool based on family health history. However, family criteria including inherited CVD risk to be used by laypersons are non-existent. In this project, we employed a qualitative study design to develop expert-based family criteria for use in individual risk assessment. In the first phase of the project, we identified potential family criteria through an online focus group with physicians with expertise in monogenic and/or multifactorial CVDs. The family criteria from phase one were then used as input for a three-round Delphi procedure carried out in a larger group of expert physicians to reach consensus on appropriate criteria. This led to consensus on five family criteria that focus on cardiovascular events at young age (i.e., sudden death, any CVD, implantable cardioverter-defibrillator, aortic aneurysm) and/or an inherited CVD in one or more close relatives. We then applied these family criteria to a high-risk cohort from a clinical genetics department and demonstrated that they have substantial diagnostic accuracy. After further evaluation in a general population cohort, we decided to only use the family criteria for first-degree relatives. We plan to incorporate these family criteria into a digital tool for easy risk assessment by the public and, based on expert advice, will develop supporting information for general practitioners to act upon potential risks identified by the tool. Results from an expert focus group, a Delphi method in a larger group of experts, and evaluation in two cohorts were used to develop family criteria for assessing cardiovascular disease risk based on family health history for a digital risk-prediction tool for use by the general population.

- Abstract
Background: Primary carnitine deficiency is an inborn error of metabolism, which can lead to life-threating complications early in life. Low carnitine levels can be detected by newborn bloodspot screening (NBS). However, NBS can also identify, mostly asymptomatic, mothers with primary carnitine deficiency. To identify mothers' needs and areas for improving screening practice, this study explored the experiences with, and opinions on primary carnitine deficiency screening in NBS among women diagnosed through NBS of their newborn., Methods: Twelve Dutch women were interviewed, 3-11 years after diagnosis. Data were analysed using a thematic approach., Results: Four main themes were derived: 1) psychological impact of primary carnitine deficiency diagnosis, 2) becoming a patient and "patient-in-waiting", 3) information issues and care provision, and 4) primary carnitine deficiency as part of the NBS panel. Mothers shared that they did not experience major psychological distress of the diagnosis. They did experience (recall) various emotions following the initial abnormal NBS result, including fear and anxiety as well as relief, and emotions regarding their own diagnosis, including uncertainty about health risks and treatment effectiveness. Some felt a patient-in-waiting. Many participants experienced a lack of information, especially shortly after receiving the abnormal NBS result. All shared the belief that screening for primary carnitine deficiency in NBS is beneficial for the newborn, and, given the information they received, also considered the knowledge beneficial for their own health., Conclusions: Psychological burden following diagnosis was experienced by women as limited, although the experienced lack of information amplified feelings of uncertainty and anxiety. Most mothers believed that benefits of knowing about primary carnitine deficiency outweighed the disadvantages. Mothers' perspectives should be incorporated in policy-making about primary carnitine deficiency in NBS., (© 2023. The Author(s).)

- Abstract
Carrier screening aims to identify couples at risk of conceiving children with a recessive condition. Until recently, carrier screening was primarily offered ancestry-based. Technological advances now facilitate expanded universal carrier screening (EUCS). This scoping review aimed to map EUCS's potential societal implications based on both theoretical studies and empirical evidence. To this aim, we performed a CoCites search to find relevant articles, including articles describing carrier screening for at-risk populations, based on five selected query articles. Forty articles were included. Three main potential societal implications were identified: (1) unwanted medicalization, (2) stigmatization and discrimination of carriers and people affected with the conditions screened and (3) challenges in achieving equitable access. Within these themes, potential positive implications are reduction of ethnic stigmatization in ancestry-based offers and increased equity. Potential negative implications are reinforcement of disability-based stigmatization, less possibility for developing expertise in healthcare and societal pressure to partake in screening. Empirical evidence on all these implications is however scarce. In conclusion, both positive and negative potential societal implications of implementing EUCS, primarily theoretical, were identified, even in at-risk groups where evidence is mostly lacking. Empirical research in EUCS pilots is needed to identify which societal implications are likely to occur and therefore should be overcome when implementing EUCS., (© 2022. The Author(s).)

- Abstract
Objective: Faster and cheaper next generation sequencing technologies have enabled expansion of carrier screening for recessive disorders, potentially facilitating population-based implementation regardless of ancestry or family history. Little is known, however, about the attitudes regarding population-based carrier screening among families with genetic disorders. This study assessed views among parents and patients with a recessive disorder and parents of children with Down syndrome (DS) on expanded carrier screening (ECS)., Method: In total, 85 patients with various recessive disorders, 110 parents of a child with a recessive disorder and 89 parents of a child with DS participated in an online survey in the Netherlands. Severity of recessive disorders was classified as mild/moderate or severe/profound., Results: The majority of the (parents of) patients with a recessive disorder had a positive attitude towards population-based ECS, including screening for their own or their child's disorder. DS parents were significantly less positive towards ECS. Subgroup analyses showed that the severity of the disorder, rather than being a patient or parent, influences the attitudes, beliefs and intention to participate in ECS., Conclusion: Our findings have important implications for future implementation initiatives as they demonstrate the different perspectives from people with experiential knowledge with genetic disorders., (© 2022 The Authors.

- Abstract
Research on the perspectives of patients and parents regarding genetic testing and its implications has been performed mostly in Europe, Canada, the United States, Australia and New Zealand, even though genetic testing is becoming increasingly available worldwide. We aimed to fill this knowledge gap by exploring the experiences and needs of parents in the Dutch Caribbean who received a genetic diagnosis for the rare disease of their child. We conducted 23 semi-structured interviews with 30 parents of children diagnosed with various rare genetic diseases in Aruba, Bonaire and Curaçao (ABC-islands). Two researchers independently analyzed the interviews using a thematic approach. Main themes identified were: (1) getting a genetic diagnosis, (2) coping, support and perceived social stigma, (3) living on a small island, and (4) needs regarding genetic services. Our results indicate that, despite reported limitations regarding the availability of healthcare and support services, receiving a genetic diagnosis for their child was valuable for most participants. While some of the participants' experiences with and attitudes towards the genetic diagnosis of their child were similar to those reported in previous studies, we identified a number of aspects that are more specifically related to this Dutch Caribbean setting. These include coping through faith and religion, social stigma and being the only one on the island with a specific genetic disorder. The results of this study and the provided recommendations may be useful when developing genetic testing and counseling services in similar settings., (© 2022.

- Abstract
Background: Genetic heart diseases (GHDs) can be clinically heterogeneous and pose an increased risk of sudden cardiac death (SCD). The implantable cardioverter-defibrillator (ICD) is a lifesaving therapy. Impacts on prospective and long-term psychological and health-related quality of life (HR-QoL) after ICD implant in patients with GHDs are unknown., Objectives: Investigate the psychological functioning and HR-QoL over time in patients with GHDs who receive an ICD, and identify risk factors for poor psychological functioning and HR-QoL., Methods: A longitudinal, prospective study design was used. Patients attending a specialized clinic, diagnosed with a GHD for which they received an ICD between May 2012 and January 2015, were eligible. Baseline surveys were completed prior to ICD implantation with 5-year follow-up after ICD implant. We measured psychological functioning (Hospital Anxiety Depression Scale, Florida Shock Anxiety Scale), HR-QoL (Short-Form 36v2), and device acceptance (Florida Patient Acceptance Scale)., Results: Forty patients were included (mean age 46.3 ± 14.2 years; 65.0% male). Mean psychological and HR-QoL measures were within normative ranges during follow-up. After 12 months, 33.3% and 19.4% of participants showed clinically elevated levels of anxiety and depression, respectively. Longitudinal mixed-effect analysis showed significant improvements from baseline to first follow-up for the overall cohort, with variability increasing after 36 months. Nontertiary education and female sex predicted worse mental HR-QoL and anxiety over time, while comorbidities predicted depression and worse physical HR-QoL., Conclusion: While the majority of patients with a GHD adjust well to their ICD implant, a subset of patients experience poor psychological and HR-QoL outcomes., (© 2022 Published by Elsevier Inc. on behalf of Heart Rhythm Society.)

- Abstract
If undetected, inherited cardiac conditions can lead to sudden cardiac death, while treatment options are available. Predictive DNA testing is therefore advised for at-risk relatives, and probands are currently asked to inform relatives about this. However, fewer than half of relatives attend genetic counselling. In this trial, we compared a tailored approach to informing relatives, in which probands were asked whether they preferred relatives to be informed by themselves or by the genetic counsellor, with current practice. Our primary outcome was uptake of genetic counselling in relatives in the first year after test result disclosure. Secondary outcomes were evaluation of the approach and impact on psychological/family functioning measured 3 (T1) and 9 (T2) months post-disclosure via telephone interviews and questionnaires. We included 96 probands; 482 relatives were eligible for counselling and genetic testing. We observed no significant difference in uptake of genetic counselling between the control (38%) and the intervention (37%) group (p = 0.973). Nor were there significant differences between groups in impact on family/psychological functioning. Significantly more probands in the tailored group were satisfied (p = 0.001) and felt supported (p = 0.003) by the approach, although they also felt somewhat coerced to inform relatives (p < 0.001) and perceived room for improvement (p < 0.001). To conclude, we observed no differences in uptake and impact on family/psychological functioning between the current and tailored approach, but probands in the tailored group more often felt satisfied. Further research on barriers to relatives attending genetic counselling and on how to optimize the provision of a tailored approach is needed., (© 2021.

- Abstract
Background: With advances in sequencing technologies, increasing numbers of people are being informed about a genetic disease identified in their family. In current practice, probands (the first person in a family in whom a genetic predisposition is identified) are asked to inform at-risk relatives about the diagnosis. However, previous research has shown that relatives are sometimes not informed due to barriers such as family conflicts. Research on family communication in genetic diseases aims to explore the difficulties encountered in informing relatives and to identify ways to support probands in this., Main Body: Research on family communication may also reveal that participants did not inform their relatives about the risk of a serious genetic condition, even when preventive and treatment options are available. Researchers may then face a dilemma: Do they need to warn at-risk relatives about the finding? Or do they keep silent due to prior confidentiality agreements with study participants?, Conclusions: We believe that the absolute confidence promised to research participants outweighs the interests of their relatives, even though it can be claimed that relatives at risk of a genetic disease do, in principle, have a right to know information collected about their health. Not respecting confidentiality agreements could cause distrust between researchers and research participants and possibly harm the relationship between probands and relatives. Relatives' health interests can still be taken into account without jeopardizing participant trust, by considering alternative scenarios, including sharing general study findings on the barriers participants experience with their healthcare professionals and by offering participants psychosocial support for family communication., (© 2021.

- Abstract
Background: Thorough investigation of sudden cardiac death (SCD) in those aged 1-40 years commonly reveals a heritable cause, yet access to postmortem genetic testing is variable., Objective: The purpose of this study was to explore practices of postmortem genetic testing and attitudes of health care professionals worldwide., Methods: A survey was administered among health care professionals recruited through professional associations, social media, and networks of researchers. Topics included practices around postmortem genetic testing, level of confidence in health care professionals' ability, and attitudes toward postmortem genetic testing practices., Results: There were 112 respondents, with 93% from North America, Europe, and Australia/New Zealand, and 7% from South America, Asia and Africa. Only 30% reported autopsy as mandatory, and overall practices were largely case by case and not standardized. North American respondents (87%) more often perceived practices as ineffective compared to those from Europe (58%) and Australia/New Zealand (48%; P = .002). Where a heritable cause is suspected, 69% considered postmortem genetic testing and 61% offered genetic counseling to surviving family members. Financial resources varied widely. Half of participants believed practices in their countries perpetuated health inequalities., Conclusion: Postmortem genetic testing is not consistently available in the investigation of young SCD despite being a recommendation in international guidelines. Access to postmortem genetic testing, which is critical in ascertaining a cause of death in many cases, must be guided by well-resourced, multidisciplinary teams., (Copyright © 2021 Heart Rhythm Society.

- Abstract
Objective: Genetic counselors need advanced communication skills, particularly when discussing tests involving massively parallel sequencing. Increasingly, non-genetic healthcare professionals (HCPs) also need to provide genetic counseling. Communication skills training (CST) may equip HCPs with the required communication skills. This scoping review provides an overview of the content, approach, effectiveness and effective features of CSTs aimed at improving genetic and non-genetic HCPs' communication skills in providing genetic counseling., Methods: Following the PRISMA-ScR statement, four databases were searched for articles. Two researchers independently screened titles and abstracts, and extracted data. When applicable, information on effectiveness and effective features of CST was collated., Results: Twenty-three articles were included. Sixteen CSTs targeted non-genetic HCPs, five targeted genetic HCPs and two targeted both. Most CSTs addressed multiple communication behaviors and consisted of role play. CSTs were found to be effective for improving HCPs (mainly self-reported) attitudes and skills. Limited evidence on specific effective features of CST was found., Conclusions: There is a clear need for evidence on the effectiveness of CST on improving both HCPs' communication skills in the context of genetic counseling, and patient outcomes, and its specific effective features., Practice Implications: Clinical practice could benefit from evidence-based CST for genetic and non-genetic HCPs., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier B.V.

- Abstract
Pulmonary arterial hypertension (PAH) is a severe, life-threatening disease, and in some cases is caused by genetic defects. This study sought to assess the diagnostic yield of genetic testing in a Dutch cohort of 126 PAH patients. Historically, genetic testing in the Netherlands consisted of the analysis of BMPR2 and SMAD9. These genes were analyzed in 70 of the 126 patients. A (likely) pathogenic (LP/P) variant was detected in 22 (31%) of them. After the identification of additional PAH associated genes, a next generation sequencing (NGS) panel consisting of 19 genes was developed in 2018. Additional genetic testing was offered to the 48 BMPR2 and SMAD9 negative patients, out of which 28 opted for NGS analysis. In addition, this gene panel was analyzed in 56 newly identified idiopathic (IPAH) or pulmonary veno occlusive disease (PVOD) patients. In these 84 patients, NGS panel testing revealed LP/P variants in BMPR2 ( N = 4), GDF2 ( N = 2), EIF2AK4 ( N = 1), and TBX4 ( N = 3). Furthermore, 134 relatives of 32 probands with a LP/P variant were tested, yielding 41 carriers. NGS panel screening offered to IPAH/PVOD patients led to the identification of LP/P variants in GDF2, EIF2AK4, and TBX4 in six additional patients. The identification of LP/P variants in patients allows for screening of at-risk relatives, enabling the early identification of PAH.

- Abstract
Background: Inherited cardiac conditions present with a wide range of symptoms and may even result in sudden cardiac death. Relatives of probands with a confirmed pathogenic genetic variant are advised predictive DNA testing to enable prevention and treatment. In 2 previous cohort studies of 115 probands with a pathogenic variant, family uptake of genetic counseling was assessed in the first year(s) after test result disclosure to the proband. This study assesses uptake in these cohorts in the 14 to 23 years following disclosure., Methods: Uptake was determined retrospectively using patient records. First-degree relatives, and second-degree relatives of a deceased first-degree relative suspected of having an inherited cardiac condition, were considered eligible., Results: Of 717 eligible relatives (598 first-degree and 119 second-degree relatives), 60% attended genetic counseling. Most of them (68.6%) attended genetic counseling in the first year. A total of 98.4% of counseled relatives pursued predictive DNA testing. A total of 49.2% was identified as carrier. Median time between disclosure to the proband and counseling of relatives was 6 months (range: 0-187 months). Attending genetic counseling was observed more frequently in first-degree relatives, female relatives, primary arrhythmia syndromes, relatives with manifest inherited cardiac condition, relatives without children and families with sudden cardiac death in first-degree relatives <40 years., Conclusions: During median follow-up of 16 years, 60.0% of relatives attended genetic counseling, with 41.0% in the first year. Our results may suggest that some relatives are not or inadequately informed or that barriers against genetic counseling are present. Further research is needed into interventions facilitating family communication, increasing awareness among families and healthcare professionals, and lowering thresholds for genetic counseling.

- Abstract
Chromosomal microarray analysis is an important diagnostic tool to identify copy number variations (CNV). Some of the CNVs affect susceptibility regions, which means that deletions or duplications in these regions have partial penetrance and often give an increased risk for a spectrum of neurocognitive disorders. Not much is known about the impact of rare CNV susceptibility syndromes on the life of patients or their parents. In this study, we focus on one specific susceptibility CNV disorder, 16p11.2 deletion syndrome. This rare condition is characterised by an increased risk of mild intellectual disability, autism spectrum disorder, epilepsy, and obesity. We aimed to explore the impact of such a disorder on the family members involved in the daily care of children with this syndrome. Three focus group discussions were held with 23 Dutch (grand)parents. Thematic analysis was performed by two independent researchers. The following five themes emerged: (1) the end of a diagnostic odyssey and response to the diagnosis, (2) after the diagnosis-life with a child with 16p11.2 deletion syndrome, (3) access to medical care and support services, (4) nobody knows what 16p11.2 deletion syndrome is, and (5) future perspective-ideal care. The participants experienced a lack of knowledge among involved professionals. Together with the large variability of the syndrome, this led to fragmented care and unfulfilled needs regarding healthcare, social, and/or educational assistance. Care for children with a CNV susceptibility syndrome could be improved by a multidisciplinary approach or central healthcare professional, providing education and information for all involved professionals.

- Abstract
When a genetic disease-causing variant causing autosomal dominant diseases is identified, predictive DNA testing is possible for at-risk relatives to investigate whether they are carrying the familial variant. In current practice, the proband is asked to inform at-risk relatives, often supported by a family letter. This review summarizes the literature on preferences of probands and relatives regarding how and by whom at-risk relatives should be informed. A search involving digital databases (Pubmed, Medline, and PsycInfo) focusing on patient attitudes toward informing relatives at risk of autosomal dominant onco-, cardio-, or neurogenetic disease, resulted in 1,431 screened records, of which 117 full-text papers were assessed. Eventually, 32 studies were selected. This review shows that a majority of participants was in favor of someone in the family to inform their at-risk relatives, with participants generally feeling responsible for informing relatives at risk themselves. However, variation in patient preferences regarding who should inform was observed. Face-to-face disclosure by the proband with additional information material for relatives provided by HCPs was most appreciated. Actively offered support of healthcare professionals was desired. In conclusion, although the family-mediated approach was appreciated by a majority of participants, support by healthcare professionals was desired. By taking patient attitudes into account, the approach used to inform at-risk relatives could be improved. Subsequently, more relatives will be informed and enabled to attend genetic counseling and make an informed decision regarding predictive DNA testing. Further research on patient attitudes, specifying for disease type and cultural background, is needed., (© 2019 National Society of Genetic Counselors.)

- Abstract
Inherited cardiac conditions (ICCs) can lead to sudden cardiac death at young age, even without previous symptoms, yet often remain undetected. To prevent sudden cardiac death, cardiac monitoring and/or predictive DNA testing is advised for at-risk relatives. Probands in whom a causal variant is detected are asked to inform their relatives about the possibility of testing, often supported by a family letter. This qualitative study investigates experiences with and attitudes toward this family-mediated approach in ICCs and explores whether and how improvements can be made. Two online focus groups were conducted with 28 healthcare professionals (HCPs) from various disciplines, as were 25 face-to-face semi-structured interviews with counselees (10 probands; 15 relatives). Data were analysed by two researchers independently using a thematic approach. Participants, both HCPs and counselees, preferred that probands inform relatives about genetic risks in ICCs, but both groups struggled with the dependency on and burden on probands to inform their relatives. To overcome this, HCPs do see a more active role for themselves in informing relatives, but prefer uniformity in procedures in order to maintain their workload. Counselees, on the other hand, prefer a tailored information provision strategy adjusted to family dynamics and the personality characteristics of relatives. In conclusion, although it is generally preferred that probands inform relatives themselves, a more active role of HCPs could be considered to overcome the dependency and burden on probands. Further research is needed to study how HCPs can engage more actively in informing at-risk relatives in current clinical genetic practise.

- Abstract
Introduction: In current practice, probands are asked to inform relatives about the possibility of predictive DNA testing when a pathogenic variant causing an inherited cardiac condition (ICC) is identified. Previous research on the uptake of genetic counselling and predictive DNA testing in relatives suggests that not all relatives are sufficiently informed. We developed a randomised controlled trial to evaluate the effectiveness of a tailored approach in which probands decide together with the genetic counsellor which relatives they inform themselves and which relatives they prefer to have informed by the genetic counsellor. Here, we present the study protocol of this randomised controlled trial., Methods: A multicentre randomised controlled trial with parallel-group design will be conducted in which an intervention group receiving the tailored approach will be compared with a control group receiving usual care. Adult probands diagnosed with an ICC in whom a likely pathogenic or pathogenic variant is identified will be randomly assigned to the intervention or control group (total sample: n=85 probands). Primary outcomes are uptake of genetic counselling and predictive DNA testing by relatives (total sample: n=340 relatives). Secondary outcomes are appreciation of the approach used and impact on familial and psychological functioning, which will be assessed using questionnaires. Relatives who attend genetic counselling will be asked to fill out a questionnaire as well., Ethics and Dissemination: Ethical approval was obtained from the Medical Ethical Committee of the Amsterdam University Medical Centres (MEC 2017-145), the Netherlands. All participants will provide informed consent prior to participation in the study. Results of the study on primary and secondary outcome measures will be published in peer-reviewed journals., Trial Registration Number: NTR6657; Pre-results., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Expanded carrier screening (ECS) aims to inform couples' reproductive choice, preferably before conception. As part of an implementation study in which trained general practitioners (GPs) offered a population-based ECS couple-test, we evaluated the feasibility of the test-offer and degree of participant informed choice (IC). Trained GPs from nine practices in the northern Netherlands invited 4295 female patients aged 18-40 to take part in couple-based ECS. Inclusion criteria were having a male partner, planning for children and not being pregnant. We evaluated the feasibility of the organizational aspects, GP competence and the content of the pre-test counselling. Participant satisfaction, evaluation of pre-test counselling and degree of IC were measured using a longitudinal survey. We explored GP experiences and their views on future implementation through semi-structured interviews. 130 consultations took place. All participating GPs were assessed by genetic professionals to be competent to conduct pre-test counselling. Most (63/108 (58%)) consultations took place within the planned 20 min (median 20, IQR 18-28). GPs considered couples' prior knowledge level an important determinant of consultation length. 91% of patients were (very) satisfied with the GP counselling. After pre-test counselling, 231/237(97%) participants had sufficient knowledge and 206/231(88%) had a positive attitude and proceeded with testing. Our pilot demonstrates that offering couple-based ECS through trained and motivated GPs is feasible. Future large-scale implementation requires a well-informed general public and a discussion about appropriate reimbursement for GPs and health care coverage for couples. Providing (more) test information pre-appointment may help reduce average consultation time.
