Abstract
Background Newborn genetic screening (NBGS) based on next-generation sequencing offers enhanced disease detection and better detection rates than traditional newborn screening. However, challenges remain, especially around reporting the NBGS carrier results. Therefore, we aimed to investigate the NBGS carrier parents' views on NBGS and NBGS reports in China. Methods We distributed a survey querying demographic information, knowledge and perceptions of NBGS, the impact of NBGS on a total of 2930 parents, and their decision-making to parents of newborns reported as carriers in NBGS in Nanjing, China in 2022. Results The average age of the survey respondents was 30.7 years (standard deviation = 3.6). Most (68.38%) felt informed about NBGS, especially women, the highly educated, and high earners. Nearly all (98.74%) saw NBGS as crucial for early disease detection, with 73.18% believing it positively impacts their future. However, 19.16% felt it might cause anxiety, especially among the less educated. Concerns included potential discrimination due to exposed genetic data and strained family ties. Many suggested NBGS coverage by medical insurance to ease financial burdens. Conclusions Through our study, we gained insights into parents' perspectives and concerns regarding the NBGS carrier result reporting, thus providing relevant information for further refinement and clinical promotion of the NBGS project.

Abstract
Glycogen storage diseases (GSDs) are a group of rare, monogenic disorders that share a defect in the synthesis or breakdown of glycogen. This Primer describes the multi-organ clinical features of hepatic GSDs and muscle GSDs, in addition to their epidemiology, biochemistry and mechanisms of disease, diagnosis, management, quality of life and future research directions. Some GSDs have available guidelines for diagnosis and management. Diagnostic considerations include phenotypic characterization, biomarkers, imaging, genetic testing, enzyme activity analysis and histology. Management includes surveillance for development of characteristic disease sequelae, avoidance of fasting in several hepatic GSDs, medically prescribed diets, appropriate exercise regimens and emergency letters. Specific therapeutic interventions are available for some diseases, such as enzyme replacement therapy to correct enzyme deficiency in Pompe disease and SGLT2 inhibitors for neutropenia and neutrophil dysfunction in GSD Ib. Progress in diagnosis, management and definitive therapies affects the natural course and hence morbidity and mortality. The natural history of GSDs is still being described. The quality of life of patients with these conditions varies, and standard sets of patient-centred outcomes have not yet been developed. The landscape of novel therapeutics and GSD clinical trials is vast, and emerging research is discussed herein.

Abstract
Predictive models in neuroimaging are increasingly designed with the intent to improve risk stratification and support interventional efforts in psychiatry. Many of these models have been developed in samples of children school-aged or older. Nevertheless, despite growing evidence that altered brain maturation during the fetal, infant, and toddler (FIT) period modulates risk for poor mental health outcomes in childhood, these models are rarely implemented in FIT samples. Applications of predictive modeling in children of these ages provide an opportunity to develop powerful tools for improved characterization of the neural mechanisms underlying development. To facilitate the broader use of predictive models in FIT neuroimaging, we present a brief primer and systematic review on the methods used in current predictive modeling FIT studies. Reflecting on current practices in more than 100 studies conducted over the past decade, we provide an overview of topics, modalities, and methods commonly used in the field and under-researched areas. We then outline ethical and future considerations for neuroimaging researchers interested in predicting health outcomes in early life, including researchers who may be relatively new to either advanced machine learning methods or using FIT data. Altogether, the last decade of FIT research in machine learning has provided a foundation for accelerating the prediction of early-life trajectories across the full spectrum of illness and health.

Abstract
Inborn errors of immunity (IEI) are a group of over 450 genetically distinct conditions associated with significant morbidity and mortality, for which early diagnosis and treatment improve outcomes. Newborn screening for severe combined immunodeficiency (SCID) is currently underway in several countries, utilising a DNA-based technique to quantify T cell receptor excision circles (TREC) and kappa-deleting recombination excision circles (KREC). This strategy will only identify those infants with an IEI associated with T and/or B cell lymphopenia. Other severe forms of IEI will not be detected. Up-front, first-tier genomic-based newborn screening has been proposed as a potential approach by which to concurrently screen infants for hundreds of monogenic diseases at birth. Given the clinical, phenotypic and genetic heterogeneity of IEI, a next-generation sequencing-based newborn screening approach would be suitable. There are, however, several ethical, legal and social issues which must be evaluated in detail prior to adopting a genomic-based newborn screening approach, and these are discussed herein in the context of IEI.

Abstract
Newborn screening for treatable disorders is one of the great public health success stories of the twentieth century worldwide. This commentary examines the potential use of a new technology, next generation sequencing, in newborn screening through the lens of the Wilson and Jungner criteria. Each of the ten criteria are examined to show how they might be applied by programmes using genomic sequencing as a screening tool. While there are obvious advantages to a method that can examine all disease-causing genes in a single assay at an ever-diminishing cost, implementation of genomic sequencing at scale presents numerous challenges, some which are intrinsic to screening for rare disease and some specifically linked to genomics-led screening. In addition to questions specific to routine screening considerations, the ethical, communication, data management, legal, and social implications of genomic screening programmes require consideration.

Abstract
PURPOSE There are, currently, conflicting opinions about the adoption of exome sequencing (ES) into the standard newborn screening program. This study aimed to explore the views of pregnant Latinas, a hard-to-reach, underserved, and understudied population, about pursuing ES for their newborns. METHODS We conducted semistructured interviews with 32 pregnant Latinas who predominately lived in rural areas and had low levels of income and education. An emergent coding approach was used to analyze the qualitative data collected. RESULTS Our entire sample believed that ES should be offered as a part of newborn screening, which could empower pregnant Latinas to better understand their children's health and take early treatment actions. Although some participants were concerned about potentially bad ES results and had questions about the accuracy of ES results, nearly all interviewees reported that they would be willing to have their newborns undergo ES. The main reasons given were to be informed of diseases that the baby may have, and the perception that ES is a procedure that involves minimal risk. CONCLUSION Pregnant Latinas in this study had favorable attitudes toward newborn ES. Their perspectives should be considered when decisions are made about incorporating ES into newborn screening.

Soc Sci Med 2022; 301:114972.

Abstract
As whole genome sequencing is being considered as a tool to deliver expanded newborn screening (NBS) globally, the range of equivocal results it could produce are gaining increased attention. For cystic fibrosis (CF) screening, the use of next generation sequencing within existing UK NBS programmes would increase the number of uncertain designations returned within results, including that of Cystic Fibrosis Screen Positive Inconclusive Diagnosis (CFSPID). However, the experiences of families already living with this designation have been under-explored. This study uses in-depth interviews to explore the perspectives of sixteen parents who received positive results from CF NBS, with varying degrees of prognostic un/certainty; parents with a child diagnosed with CF (n = 6), CF carrier status (n = 3) and those with the CFSPID designation (n = 7). The biographically disruptive nature of positive NBS results-regardless of immediate relevance to the child-dominated early experiences of positive results across all groups. For those with CF, biographical reparation involved becoming 'a CF family', underscoring biological kinship bonds and reinforcing familial identity. For those with uncertain results, biographical re-calibration was more complex. Diagnostic and prognostic uncertainty posed a barrier to entry for both the 'CF world' and the 'healthy kid' world, leading parents to attempt to minimise its role, either through rejection, or re-interpretation of their child's result. Other parents, however, experienced biographical reparation more dynamically. The concept of 'genetic nomadism' captures accounts of oscillation between the two worlds; movements that were responsive to evolving health experiences, as well as social, environmental and temporal factors. Through the concept of genetic nomadism, this paper delineates both the productive, as well as divisive, nature of uncertainty for biographical reparation in the aftermath of NBS, as well as the strategies parents use to harness it, in order to successfully navigate the world with a child with an ambiguous genetic future.

Abstract
In Austria, newborns have been screened for cystic fibrosis (CF) by analyzing immunoreactive trypsinogen (IRT) from dried blood spots (DBS)s for nearly 20 years. Recently, pancreatitis-associated protein (PAP) analysis was introduced as a second-tier test with the aim of reducing recalls for second DBS cards while keeping sensitivity high. For 28 months, when IRT was elevated (65–130 ng/mL), PAP was measured from the first DBS (n = 198,927) with a two-step cut-off applied. For the last 12 months of the observation period (n = 85,421), an additional IRT×PAP cut-off was introduced. If PAP or IRT×PAP were above cut-off, a second card was analyzed for IRT and in case of elevated values identified as screen-positive. Above 130 ng/mL IRT in the first DBS, newborns were classified as screen-positive. IRT analysis of first DBS resulted in 1961 (1%) tests for PAP. In the first 16 months, 26 of 93 screen-positive were confirmed to have CF. Two false-negatives have been reported (sensitivity = 92.8%). Importantly, less than 30% of families compared to the previous IRT-IRT screening scheme had to be contacted causing distress. Adding IRT×PAP caused a marginally increased number of second cards and sweat tests to be requested during this period (15 and 3, respectively) compared to the initial IRT-PAP scheme. One case of confirmed CF was found due to IRT×PAP, demonstrating an increase in sensitivity. Thus, the relatively simple and economical algorithm presented here performs effectively and may be a useful model for inclusion of CF into NBS panels or modification of existing schemes.
