The ethics of polygenic scores in psychiatry: minefield or opportunity for patient-centered psychiatry?
Recent advancements in psychiatric genetics have sparked a lively debate on the opportunities and pitfalls of incorporating polygenic scores into clinical practice. Yet, several ethical concerns have been raised, casting doubt on whether further development and implementation of polygenic scores would be compatible with providing ethically responsible care. While these ethical issues warrant thoughtful consideration, it is equally important to recognize the unresolved need for guidance on heritability among patients and their families. Increasing the availability of genetic counseling services in psychiatry should be regarded as a first step toward meeting these needs. As a next step, future integration of novel genetic tools such as polygenic scores into genetic counseling may be a promising way to improve psychiatric counseling practice. By embedding the exploration of polygenic psychiatry into the supporting environment of genetic counseling, some of the previously identified ethical pitfalls may be prevented, and opportunities to bolster patient empowerment can be seized upon. To ensure an ethically responsible approach to psychiatric genetics, active collaboration with patients and their relatives is essential, accompanied by educational efforts to facilitate informed discussions between psychiatrists and patients
Cancer patients' intentions towards receiving unsolicited genetic information obtained using next-generation sequencing
Next-generation sequencing (NGS) can be used to generate information about a patient's tumour and personal genome. This powerful diagnostic tool provides solicited and unsolicited hereditary genetic (risk) information that could have consequences for cancer patients and their quality of life. A well-defined approach for returning appropriate genetic risk information is needed in personalized cancer care. A qualitative design with semi-structured interviews was used. We conducted interviews with 24 Dutch patients with different types of cancer, both NGS-experienced and NGS-inexperienced, to learn their intentions, needs and preferences towards receiving unsolicited genetic information obtained using NGS. Almost all participants had a positive attitude towards receiving unsolicited findings. After receiving comprehensive background information on NGS, including a binning model of four categories of unsolicited findings, most participants preferred to receive only subsets of genetic information. Their main concern was their own and others' (including family members) ability to cope with (the increased risk of having) a genetic disorder. Providing background information gave cancer patients the opportunity to select subsets of findings and increased their ability to make an informed choice. Special attention is needed for social and emotional factors to support the patients themselves and when communicating test results with their family members
Am I my Family's Keeper? : Disclosure Dilemmas in Next Generation Sequencing
Ever since genetic testing is possible for specific mutations, ethical debate has sparked on the question of whether professionals have a duty to warn not only patients but also their relatives that might be at risk for hereditary diseases. As next generation sequencing swiftly finds its way into clinical practice, the question who is responsible for conveying unsolicited findings to family members becomes increasingly urgent. Traditionally, there is a strong emphasis on the duties of the professional in this debate. But what is the role of the patient and her family? In this article, we discuss the question of whose duty it is to convey relevant genetic risk information concerning hereditary diseases that can be cured or prevented to the relatives of patients undergoing NGS. We argue in favor of a shared responsibility for professionals and patients and present a strategy that reconciles these roles: a moral accountability nudge. Incorporated into informed consent and counseling services such as letters and online tools, this nudge aims to create awareness on specific patient responsibilities. Commitment of all parties is needed to ensure adequate dissemination of results in the NGS era. This article is protected by copyright. All rights reserved

Parents' experiences with large-scale sequencing for genetic predisposition in pediatric renal cancer: A qualitative study
Objective: In pediatric oncology, large-scale genetic sequencing contributes to the identification of cancer predisposition, which can facilitate surveillance and family counseling. Our qualitative study explores families' motives, knowledge, and views regarding germline genetic sequencing to improve future counseling and support. Methods: Semi-structured interviews were conducted with parents of children with renal tumors participating in a national center, germline sequencing study. An inductive thematic analysis approach was used. Twenty nine parents participated, 17 mothers and 12 fathers. The median age of the affected children was 4Â years. Results: Parents were generally positive about sequencing and reported a combination of individual and altruistic motives to participate. Some families counseled about sequencing shortly after cancer diagnosis felt overwhelmed. Many parents had difficulties distinguishing between panel and exome-wide analysis. Families in which no predisposition was identified felt reassured. Most families did not experience distress after a predisposition was disclosed, although sometimes stress following disclosure of a predisposition added to pre-existing (cancer-related) stress. Conclusions: Even though families reported positive experiences with germline genetic sequencing to detect cancer predisposition, timing of consent for sequencing as well as parents' understanding of genetic concepts can be further improved
Nationwide analysis of hospital variation in preoperative radiotherapy use for rectal cancer following guideline revision
Introduction: The revised Dutch colorectal cancer guideline (2014), led to an overall decrease in preoperative radiotherapy (RT) use. This study evaluates hospital variation in RT use for resectable rectal cancer and the influence of guideline revision, including the nationwide impact of changing RT application on short term outcomes. Methods: Data of surgically resected rectal cancer patients registered in the Dutch ColoRectal Audit were extracted between 2011 and 2017. Patients were divided into groups based on time of guideline revision (<2014 and ≥ 2014). Primary outcome was guideline adherence at hospital level regarding RT application, stratified for three stage groups. Secondary outcomes included positive circumferential resection (CRM+) and 30-day complicated postoperative course. Results: The groups consisted of 7364 and 12,057 patients, respectively. In total, 6772 patients did not receive RT (17.6% (<2014) vs. 45.7% (≥2014), p < 0.001). The largest increase of surgery alone was observed for cT1-2N0 stage rectal cancer (35.1% vs. 91.8%, p < 0.001), with a substantial decrease in hospital variation (IQR 22.2–50.0% vs. IQR 87.6–98.0%). For cT1-3N1MRF- stage rectal cancer, a substantial amount of hospital variation in short course RT remained after guideline revision (IQR 26.8–54.1% vs. IQR 26.2–50.0%). A significant decrease in CRM+ (5.8% vs. 4.2%, p < 0.001) and complicated course (22.5% vs. 18.5%, p < 0.001) was observed. Conclusions: Radiotherapy for early-stage rectal cancer was uniformly abandoned after guideline revision, while substantial hospital variation remained for intermediate risk resectable rectal cancer in the Netherlands. The substantial nationwide decrease in the use of RT for rectal cancer treatment did not negatively impact CRM involvement
Identification of an Amino Acid Motif in HLA–DRβ1 That Distinguishes Uveitis in Patients With Juvenile Idiopathic Arthritis
Objective: Uveitis is a visually debilitating disorder that affects up to 30% of children with the most common forms of juvenile idiopathic arthritis (JIA). The disease mechanisms predisposing only a subgroup of children to uveitis are unknown. This study was undertaken to identify genetic susceptibility loci for uveitis in JIA, using a genome-wide association study in 522 children with JIA. Methods: Two cohorts of JIA patients with ophthalmologic follow-up data were genotyped. Data were then imputed using a genome-wide imputation reference panel, and an HLA-specific reference panel was used for imputing amino acids and HLA types in the major histocompatibility complex (MHC). After imputation, genome-wide and MHC-specific analyses were performed, and a reverse immunology approach was utilized to model antigen presentation at 13 common HLA–DRβ1 alleles. Results: Presence of the amino acid serine at position 11 (serine 11) in HLA–DRβ1 was associated with an increased risk of uveitis in JIA patients (odds ratio [OR] 2.60, P = 5.43 × 10−10) and was specific to girls (Pfemales = 7.61 × 10−10 versus Pmales = 0.18). Serine 11 resides in the YST motif in the peptide-binding groove of HLA–DRβ1; all 3 amino acids in this motif are in perfect linkage disequilibrium and show identical association with disease. Quantitative prediction of binding affinity revealed that HLA–DRβ1 alleles with the YST motif could be distinguished on the basis of discernable peptide-binding preferences. Conclusion: These findings highlight a genetically distinct, sexually dimorphic feature of JIA with uveitis as compared to JIA without uveitis. The association could be indicative of the potential involvement of antigen presentation by HLA–DRβ1 in the development of uveitis in JIA. The results of this study may advance our progress toward improved treatments for, and possible prevention of, the sight-threatening complications of uveitis in children with JIA
