Precision medicine and Friedreich ataxia: promoting equity, beneficence, and informed consent for novel gene therapies

Friedreich Ataxia (FA) is an incurable neurodegenerative disease with systemic consequences affecting vital organs including those of the central and peripheral nervous systems. This article will use FA as an example to explore some of the practical and ethical issues emerging in precision medicine for rare diseases. It will first describe the existing management strategies available for FA patients, before considering the potential impact of gene therapy trials on the prevention and treatment of disease symptoms. Finally, ethical considerations will be discussed, including equity of access and managing resource allocation dilemmas; balancing benefits, burdens and harms; and gaining informed consent for novel treatments.

The clinical, mechanistic, and social impacts of air pollution on atopic dermatitis

Atopic dermatitis (AD) is a complex disease characterized by dry, pruritic skin and significant atopic and psychological sequelae. Although AD has always been viewed as multifactorial, early research was dominated by overlapping genetic determinist views of either innate barrier defects leading to inflammation or innate inflammation eroding skin barrier function. Since 1970, however, the incidence of AD in the United States has increased at a pace that far exceeds genetic drift, thus suggesting a modern, environmental etiology. Another implicated factor is Staphylococcus aureus; however, a highly contagious microorganism is unlikely to be the primary etiology of a noncommunicable disease. Recently, the roles of the skin and gut microbiomes have received greater attention as potentially targetable drivers of AD. Here too, however, dysbiosis on a population scale would require induction by an environmental factor. In this review, we describe the evidence supporting the environmental hypothesis of AD etiology and detail the molecular mechanisms of each of the AD-relevant toxins. We also outline how a pollution-focused paradigm demands earnest engagement with environmental injustice if the field is to meaningfully address racial and geographic disparities. Identifying specific toxins and their mechanisms can also inform in-home and national mitigation strategies.

Genomic Answers for Kids: Toward more equitable access to genomic testing for rare diseases in rural populations

Next-generation sequencing has revolutionized the speed of rare disease (RD) diagnoses. While clinical exome and genome sequencing represent an effective tool for many RD diagnoses, there is room to further improve the diagnostic odyssey of many RD patients. One recognizable intervention lies in increasing equitable access to genomic testing. Rural communities represent a significant portion of underserved and underrepresented individuals facing additional barriers to diagnosis and treatment. Primary care providers (PCPs) at local clinics, though sometimes suspicious of a potential benefit of genetic testing for their patients, have significant constraints in pursuing it themselves and rely on referrals to specialists. Yet, these referrals are typically followed by long waitlists and significant delays in clinical assessment, insurance clearance, testing, and initiation of diagnosis-informed care management. Not only is this process time intensive, but it also often requires multiple visits to urban medical centers for which distance may be a significant barrier to rural families. Therefore, providing early, "direct-to-provider" (DTP) local access to unrestrictive genomic testing is likely to help speed up diagnostic times and access to care for RD patients in rural communities. In a pilot study with a PCP clinic in rural Kansas, we observed a minimum 5.5 months shortening of time to diagnosis through the DTP exome sequencing program as compared to rural patients receiving genetic testing through the "traditional" PCP-referral-to-specialist scheme. We share our experience to encourage future partnerships beyond our center. Our efforts represent just one step in fostering greater diversity and equity in genomic studies.

Genetic research and the collective good: participants as leaders to reconcile individual and public interests

This paper problematises the notions of public or common good as weighed against individual sovereignty in the context of medical research by focusing on genetic research. We propose the notion of collective good as the good of the particular collective in which the research was conducted. We conducted documentary and interview-based research with participant representatives and research leaders concerned with participant involvement in leading genetic research projects and around two recent genetic data controversies: the case of the UK Wellcome Sanger Institute, accused of planning unauthorised commercialisation of African DNA samples, and the case of the company Genuity Science, which planned genetic research on brain tumour samples in Ireland with no explicit patient consent. We advocate for greater specificity in circumscribing the collective to which genetic research relates and for greater efforts in including representatives of this collective as research coleaders in order to enable a more inclusive framing of the good arising from such research. Such community-based participant cogovernance and coleadership in genetic research is vital especially when minorities or vulnerable groups are involved, and it centrally requires community capacity building to help collectives articulate their own notions of the collective good.
