Views of patients and parents of children with genetic disorders on population-based expanded carrier screening

Parental genetic knowledge and attitudes toward childhood with genetic disorders

Introduction: Genetics' integration with society sparks a multifaceted exploration in medicine, ethics, and psychology. This survey probes parental perspectives on childhood genetic disorders, aiming to gauge their understanding, attitudes, and implications. It seeks to inform healthcare, counseling, and policy endeavors by uncovering gaps in knowledge and attitudes. Understanding the psychological impact and familial dynamics of genetic information underscores the need for tailored support services amidst rapid advancements in genetic technologies and their ethical complexities. Methodology: It is a cross-sectional survey that assesses parental genetic knowledge and attitudes towards childhood genetic disorders. Data is collected by both paper and electronic formats. Data is cleaned in Excel and analyzed in IBM SPSS 29. Results: Our study included 138 participants, predominantly female (71.7%), with mean age 36.01 years (SD = 8.7). Most were Saudi (81.2%), with university education (65.9%). Notably, 73.2% reported consanguineous marriages. Regarding knowledge, 73.2% demonstrated good understanding of genetic disorders of child. Moreover, 47.8% and 34.1% claimed 40%-60% and 34.1% knowledge levels, respectively. Doctors were the primary information source (79.7%). Participants expressed moderate impact of genetic disorders on their child's life (65.9%) and family dynamics (45.7%). Satisfaction with medical care was high (41.3% rated it as excellent). Challenges accessing healthcare were reported by 52.9%. Positive experiences with genetic disorders were reported by 62.3%, with male participants more likely to report positive experiences (B = 0.888, p = 0.041). Improvement areas included treatment availability (39.1%) and advanced medical tests (20.3%). Notably, informing relatives about the genetic disease significantly predicted positive attitudes (B = 1.006, p = 0.008). Overall, obtaining information from doctors significantly enhanced knowledge (B = 2.296, p = 0.024). Conclusion: Our study shows significant associations between parental knowledge, attitudes towards genetic disorders, and healthcare experiences. It underscores the importance of informed decision-making and targeted interventions to address challenges and improve outcomes in managing childhood genetic disorders.

Should genes for non-syndromic hearing loss be included in reproductive genetic carrier screening: Views of people with a personal or family experience of deafness

Many commercial reproductive genetic carrier screening (RGCS) panels include genes associated with non-syndromic hearing loss (NSHL), however little is known about the general acceptability of their inclusion. Although some couples wish to avoid having a deaf child, there are effective interventions and supports available for deafness, and no consensus on whether it is appropriate to reproductively screen NSHL genes. This study explored views of people with personal experience of deafness regarding carrier screening for genes associated with NSHL. We interviewed 27 participants; 14 who identified as deaf and 13 hearing parents of a deaf child. Thematic analysis was undertaken on transcripts of interviews. The findings reveal the complexity of attitudes within these groups. Some vacillated between the wish to support prospective parents' reproductive autonomy and concerns about potential harms, especially the expression of negative messages about deafness and the potential loss of acceptance in society. While some participants felt carrier screening could help prospective parents to prepare for a deaf child, there was little support for reproductive screening and termination of pregnancy. Participants emphasized the need for accurate information about the lived experience of deafness. The majority felt deafness is not as severe as other conditions included in RGCS, and most do not consider deafness as a disability. People with personal experience of deafness have diverse attitudes towards RGCS for deafness informed by their own identify and experience, and many have concerns about how it should be discussed and implemented in a population wide RGCS program.

Reproductive Counseling and Care in Cystic Fibrosis: A Multidisciplinary Approach for a New Therapeutic Era

With the advent of highly effective modulator therapies, many people with cystic fibrosis (CF) are living longer, healthier lives. Pregnancy rates for women with CF more than doubled between 2019 and 2021, reflecting increases in both planned and unplanned pregnancies. For men with CF, CF-associated infertility can be mitigated with assistive reproductive technology, yet patient knowledge of these challenges and options is variable. Preconception and prenatal counseling for individuals with CF and for parents of children with CF who wish to expand their families requires nuanced discussions to promote informed reproductive decisions, drawing from a combination of standard practice recommendations and CF-specific assessments. This review article synthesizes the current literature and practice recommendations regarding reproductive counseling and care in CF, outlining the role of genetic counseling, carrier screening, teratogen counseling, in vitro fertilization and pre-implantation genetic diagnosis, and careful assessment and management of cystic fibrosis-related diabetes when present. Via a multidisciplinary, patient-centered approach, clinicians can support adults with CF and parents of children with CF as they make informed reproductive decisions and embark on family planning.

Expressivist objections to prenatal screening and testing: Perceptions of people living with disability

The 'expressivist objection' (EO) refers to the notion that using reproductive (genetic) technologies to prevent the birth of future would-be disabled people contain, and express, a negative valuation of life with disability. Whilst the EO has received increased attention in recent years in line with rapid technological and genomic developments, there remains scant research on how EO concerns are experienced and expressed by disabled people and their families, especially within and between impairment groups. Bringing together two studies-one with adults and family members living with genetic conditions (n = 62) and one with parents of children with Down's syndrome (n = 22)-we argue that disabled people and their families variously embrace, reject or rework the EO across contexts, and yet also frequently situate it within broad support for reproductive technologies. We present three key factors that mediate responses to the EO: (1) the nature of impairment and its integration within identity; (2) social and cultural contexts relating to disability and (3) the (individual and collective) imagined futures of disabled people. In so doing, we blend the conceptual architecture of medical sociology and disability studies, arguing that this allows us to accurately illuminate the nuanced responses of disabled people and their families.

Preconception Expanded Carrier Screening: A Discourse Analysis of Dutch Webpages

Preconception expanded carrier screening (PECS) informs prospective parents about the risk of conceiving a child with a heritable genetic condition. PECS will also, for many, become an important screening test, and websites will likely play a vital role in providing information on this practice. The aim of this article is to examine rationalities in the information on PECS on Dutch websites. The method used is multimodal critical discourse analysis. This method allows an examination of norms and assumptions in the descriptions, as well as of the positions that are discursively made available. The data consist of publicly available material on websites from two genetics departments in the Netherlands. In the results, we present the three main discourses and subject positions that were identified: risk and the couple as possible mediators of severe conditions; the focus on scientific facts and rational conceivers; and severity of the conditions and the responsible couple. In this study, we highlight the importance of acknowledging the interrelation between epistemology and ethics in the discourse on PECS. Finally, it is claimed that the focus on scientific facts in information on PECS risks making existential and ethical dilemmas and choices invisible.

Views of reproductive genetic carrier screening participants regarding screening for genes associated with non-syndromic hearing loss

OBJECTIVE

Reproductive genetic carrier screening (RGCS) panels often include genes associated with non-syndromic hearing loss (NSHL) despite a lack of evidence of acceptability. Although some couples take steps to avoid having a child who is deaf, there are effective interventions for children who are deaf. There is no consensus whether deafness is considered a disabling condition.

METHOD

This study explored views of people who had RGCS, without genes for NSHL, about this topic. Online surveys were sent to 2186 people who had a low chance RGCS result and 655 completed the survey (participation rate 30%).

RESULTS

Sixty-three percent (N = 412) think deafness is a serious health condition. The majority agreed (60%, N = 391) that with support (i.e. hearing aids/cochlear implants) deafness is a minor condition in children. Most (84%, N = 545) agreed genes for NSHL should be included in RGCS. Thirty-five percent (N = 231) indicated they would make different reproductive decisions if they had an increased chance of having a child born deaf; 31% would not change their reproductive plans and 34% were unsure what they would do.

CONCLUSION

While the majority support inclusion of genes associated with NSHL in RGCS, there was uncertainty about the severity of deafness as a health condition and there was no consensus on whether it is a health condition that warrants changing reproductive decisions.
