Impact of the increased adoption of prenatal cfDNA screening on non-profit patient advocacy organizations in the United States

Never "totally prepared": Support groups on helping families prepare for a child with a genetic condition

A rapid increase in the reach and breadth of prenatal genetic screening and testing has led to an expanding need for prenatal support of families receiving this genetic information. As part of a larger study investigating prenatal preparation for a child with a genetic condition, we interviewed representatives of patient advocacy groups (PAGs) who support parents post-diagnosis. Groups supporting families with Down syndrome were often local or regional, while other groups were often national or international in scope. Groups varied in their willingness or ability to support families prior to making a pregnancy continuation decision, and participants reflected on ways they addressed these needs with individual counseling and referrals, if needed. Participants described supporting parents with information about conditions and a range of lived experiences for families, while referring families to healthcare professionals for technical questions and additional medical needs. PAGs also prioritized connecting parents experiencing a new diagnosis with other families for peer support and community-building, both in person and on social media. Participants discussed limitations, such as a lack of racially-concordant support, ability to offer resources in languages other than English, and a lack of funding to meet the expressed needs of families post-diagnosis. Overall, participants emphasized that the parenting experience of each child is unique, irrespective of a genetic diagnosis, an experience for which parents can never be "totally prepared."

From late fatherhood to prenatal screening of monogenic disorders: evidence and ethical concerns

BACKGROUND

With the help of ART, an advanced parental age is not considered to be a serious obstacle for reproduction anymore. However, significant health risks for future offspring hide behind the success of reproductive medicine for the treatment of reduced fertility associated with late parenthood. Although an advanced maternal age is a well-known risk factor for poor reproductive outcomes, understanding the impact of an advanced paternal age on offspring is yet to be elucidated. De novo monogenic disorders (MDs) are highly associated with late fatherhood. MDs are one of the major sources of paediatric morbidity and mortality, causing significant socioeconomic and psychological burdens to society. Although individually rare, the combined prevalence of these disorders is as high as that of chromosomal aneuploidies, indicating the increasing need for prenatal screening. With the help of advanced reproductive technologies, families with late paternity have the option of non-invasive prenatal testing (NIPT) for multiple MDs (MD-NIPT), which has a sensitivity and specificity of almost 100%.

OBJECTIVE AND RATIONALE

The main aims of the current review were to examine the effect of late paternity on the origin and nature of MDs, to highlight the role of NIPT for the detection of a variety of paternal age-associated MDs, to describe clinical experiences and to reflect on the ethical concerns surrounding the topic of late paternity and MD-NIPT.

SEARCH METHODS

An extensive search of peer-reviewed publications (1980-2021) in English from the PubMed and Google Scholar databases was based on key words in different combinations: late paternity, paternal age, spermatogenesis, selfish spermatogonial selection, paternal age effect, de novo mutations (DNMs), MDs, NIPT, ethics of late fatherhood, prenatal testing and paternal rights.

OUTCOMES

An advanced paternal age provokes the accumulation of DNMs, which arise in continuously dividing germline cells. A subset of DNMs, owing to their effect on the rat sarcoma virus protein-mitogen-activated protein kinase signalling pathway, becomes beneficial for spermatogonia, causing selfish spermatogonial selection and outgrowth, and in some rare cases may lead to spermatocytic seminoma later in life. In the offspring, these selfish DNMs cause paternal age effect (PAE) disorders with a severe and even life-threatening phenotype. The increasing tendency for late paternity and the subsequent high risk of PAE disorders indicate an increased need for a safe and reliable detection procedure, such as MD-NIPT. The MD-NIPT approach has the capacity to provide safe screening for pregnancies at risk of PAE disorders and MDs, which constitute up to 20% of all pregnancies. The primary risks include pregnancies with a paternal age over 40 years, a previous history of an affected pregnancy/child, and/or congenital anomalies detected by routine ultrasonography. The implementation of NIPT-based screening would support the early diagnosis and management needed in cases of affected pregnancy. However, the benefits of MD-NIPT need to be balanced with the ethical challenges associated with the introduction of such an approach into routine clinical practice, namely concerns regarding reproductive autonomy, informed consent, potential disability discrimination, paternal rights and PAE-associated issues, equity and justice in accessing services, and counselling.

WIDER IMPLICATIONS

Considering the increasing parental age and risks of MDs, combined NIPT for chromosomal aneuploidies and microdeletion syndromes as well as tests for MDs might become a part of routine pregnancy management in the near future. Moreover, the ethical challenges associated with the introduction of MD-NIPT into routine clinical practice need to be carefully evaluated. Furthermore, more focus and attention should be directed towards the ethics of late paternity, paternal rights and paternal genetic guilt associated with pregnancies affected with PAE MDs.

The Emergence and Global Spread of Noninvasive Prenatal Testing

Since its introduction in 2011, noninvasive prenatal testing (NIPT) has spread rapidly around the world. It carries numerous benefits but also raises challenges, often related to sociocultural, legal, and economic contexts. This article describes the implementation of NIPT in nine countries, each with its own unique characteristics: Australia, Canada, China and Hong Kong, India, Israel, Lebanon, the Netherlands, the United Kingdom, and the United States. Themes covered for each country include the structure of the healthcare system, how NIPT is offered, counseling needs and resources, and cultural and legal context regarding disability and pregnancytermination. Some common issues emerge, including cost as a barrier to equitable access, the complexity of decision-making about public funding, and a shortage of appropriate resources that promote informed choice. Conversely, sociocultural values that underlie the use of NIPT vary greatly among countries. The issues described will become even more challenging as NIPT evolves from a second-tier to a first-tier screening test with expanded use.

Culpable Ignorance, Professional Counselling, and Selective Abortion of Intellectual Disability

In this paper I argue that selective abortion for disability often involves inadequate counselling on the part of reproductive medicine professionals who advise prospective parents. I claim that prenatal disability clinicians often fail in intellectual duty-they are culpably ignorant about intellectual disability (or do not disclose known facts to parents). First, I explain why a standard motivation for selective abortion is flawed. Second, I summarize recent research on parent experience with prenatal professionals. Third, I outline the notions of epistemic excellence and deficiency. Fourth, I defend culpable ignorance as the best explanation of inadequate disability counselling. Fifth, I rebut alternative explanations. My focus is pregnancies diagnosed with mild or moderate intellectual disability.

Epistemic Virtue, Prospective Parents and Disability Abortion

Research shows that a high majority of parents receiving prenatal diagnosis of intellectual disability terminate pregnancy. They have reasons for rejecting a child with intellectual disabilities-these reasons are, most commonly, beliefs about quality of life for it or them. Without a negative evaluation of intellectual disability, their choice makes no sense. Disability-based abortion has been critiqued through virtue ethics for being inconsistent with admirable moral character. Parental selectivity conflicts with the virtue of acceptingness (the commitment to welcome whatever child comes naturally) and exhibits the vice of wilfulness (the project of picking and choosing what children one will take). In this paper I claim that, beyond failures of moral virtue, disability abortion often involves failures of epistemic virtue on the part of parents. I argue two things: parents believe something false, or at least contested, about life with intellectual disability-and they do so because they are not epistemically conscientious. I first explain why a central motivation for disability abortion-that it prevents harm to the child-is mistaken. I next give a brief account of intellectual virtue and culpable ignorance. I then indicate why many parents fail to be intellectually virtuous when choosing to terminate pregnancy. I focus on elimination of intellectual disability and have little to say about physical and sensory impairments.

What education, background, and credentials are required to provide genetic counseling?

Technological advances in genetics have resulted in an increase in the number and complexity of screening and diagnostic tests in the prenatal clinical arena. It is critical that patients are provided with appropriate counseling to enable them to make educated decisions. During this workshop session participants discussed the education, background and credentials required to provide counseling regarding prenatal genetic testing options. The participants agreed that prenatal care providers may have limited time and training to adequately address prenatal genetic testing. Telemedicine and online education may help to address this challenge. Workshop participants agreed that educational and certifying organizations should work together to develop standards for the certification and maintenance of certification processes.
