The 100,000 Genomes Project (100kGP)-a hybrid clinical-research initiative-was set up to analyse whole genome sequences (WGS) from patients living with a rare disease or cancer. The project positioned participant consent as being of central importance, but consent in the context of genomic testing raises challenging issues. In this mixed-method study, we surveyed 1,337 100kGP participants regarding their experiences of taking part in the project and conducted in-depth interviews with 24 survey respondents to explore these findings further. Survey responses were analysed using descriptive statistics and interview data were analysed thematically. The consent approach of the 100kGP resulted in a proportion of our study's participants not understanding the complexities of the project and what types of results they might receive; for example, 20% of participants in the cancer arm did not recall what decisions they had made regarding additional findings. It is not surprising that a project such as this, with such diverse aims and participant groups, would throw up at least some challenges. However, participants reported being satisfied with their experience of the project to date. Our study highlights that in the context of consent for more complex endeavours, such as the 100kGP, it is important to assess (and document) an agreement to take part, but complicated decisions about what and when to communicate may need revisiting over time in response to changing contexts. We discuss the implications of our findings with reference to participants of the 100kGP and the newly formed NHS Genomic Medicine Service.

Technological advances have seen the offer of genome sequencing becoming part of mainstream medical practice. Research has elicited patient and health professional views on the ethical issues genome sequencing raises, however, we know little about the general public's views. These views offer an insight into people's faith in such technologies, informing discussion regarding the approach to consent in clinic. We aimed to garner public views regarding genome sequencing, incidental findings (IFs), and sharing genetic information with relatives. Participants (n = 1954) from the British general public completed a survey, distributed via email. Overall, the public had a positive view of genomic sequencing, choosing 'informative' as the most popular word (52%) and 'family legacy' as the most popular analogy (33%) representing genomic sequencing for them. Fifty-three percent agree that their relative had the right to be told about genetic information relevant to them. Fifty-four percent would expect to be told about IFs whether they had asked for them or not. Clinical practice needs to acknowledge these perspectives and expectations in order to facilitate meaningful discussion during the consent process for genomic tests. We suggest that: (a) optimistic perspectives on the usefulness of genomic tests need to be tempered by discussion in clinic about the likelihood that genomic results might be uninformative, uncertain or unexpected; (b) discussions regarding the familial nature of results are needed before testing: the majority of patients will welcome this and any concerns can be explored further; and (c) a wider discussion is required regarding the consent approach for genomic testing.

Challenges in SRS during childhood and adolescence were central to the psychosocial impact of SRS, and were not limited to height. These challenges, as well as symptoms such as pain and fatigue for women, have not previously been documented. To help individuals with SRS develop strategies to manage psychosocial issues, we recommend clinicians incorporate psychological services as an integral part of multidisciplinary teams managing individuals with SRS during childhood, adolescence and adulthood.

BackgroundSilver-Russell syndrome is an imprinting disorder that restricts growth, resulting in short adult stature that may be ameliorated by treatment. Approximately 50% of patients have loss of methylation of the imprinting control region (H19/IGF2:IG-DMR) on 11p15.5 and 5%–10% have maternal uniparental disomy of chromosome 7. Most published research focuses on the childhood phenotype. Our aim was to describe the phenotypic characteristics of older patients with SRS.MethodsA retrospective cohort of 33 individuals with a confirmed molecular diagnosis of SRS aged 13 years or above were carefully phenotyped.ResultsThe median age of the cohort was 29.6 years; 60.6% had a height SD score (SDS) ≤−2 SDS despite 70% having received growth hormone treatment. Relative macrocephaly, feeding difficulties and a facial appearance typical of children with SRS were no longer discriminatory diagnostic features. In those aged ≥18 years, impaired glucose tolerance in 25%, hypertension in 33% and hypercholesterolaemia in 52% were noted. While 9/33 accessed special education support, university degrees were completed in 40.0% (>21 years). There was no significant correlation between quality of life and height SDS. 9/25 were parents and none of the 17 offsprings had SRS.ConclusionHistorical treatment regimens for SRS were not sufficient for normal adult growth and further research to optimise treatment is justified. Clinical childhood diagnostic scoring systems are not applicable to patients presenting in adulthood and SRS diagnosis requires molecular confirmation. Metabolic ill-health warrants further investigation but SRS is compatible with a normal quality of life including normal fertility in many cases.
