How do women talk about self-funded breast cancer genetic testing?: Small stories and stance-taking strategies.

Genetic testing for breast cancer genes is an experience which is inextricably linked with health communication practices and the broader social context in which it occurs. Linguistic approaches can provide perspective on how women seeking self-funded BRCA1/2 gene testing represent their experiences, knowledge, roles, choices and emotions through the way they talk. A discursive constructionist epistemology and narrative theoretical framework informed the applied linguistics methodology. Analysis of 'small stories' and stance-taking was performed on eight transcripts of audio-recorded telephone interviews with women at low to moderate risk of carrying BRCA1/2 pathogenic variants who self-funded genetic testing. We found a high prevalence of 'small stories' including accounts of events, hypotheticals, habitual narratives, and stories which combined multiple genres. Stance-taking was a means by which participants constructed personal identities in the conversational context, such as that of a responsible person. Via stance-taking strategies, participants also actively negotiated the conversational agenda, for example expressing different degrees of alignment with the interviewer's orientation towards emotions. This study provides a basis for recognizing linguistic markers in genetic counseling interactions about genetic testing for breast cancer genes. Enhanced awareness of client language choice, and the ways in which small stories and stance can signify the client's evaluation of experience and choices, alignment with the genetic counselor's questions/statements, and investment in the conversation, has potential to improve the therapeutic interaction.

An incidental finding in prenatal exome sequencing-A case study and review of the clinical and ethical considerations.

The introduction of genomic testing into prenatal care has come at a rapid pace and has been met with significant clinical and ethical challenges, specifically when dealing with incidental findings. We present the case of a couple in their first pregnancy who were referred to our institution with isolated fetal cataracts on morphology scan. After an unremarkable infectious disease workup and microarray on an amniocentesis sample, the couple opted for fetal whole-exome sequencing to investigate the cataracts further. This investigation did not find any cause for the cataracts but yielded an incidental finding of a de novo pathogenic variant in the SCN1A gene unrelated to the cataracts. Pathogenic variants in the SCN1A gene are strongly associated with severe myoclonic epilepsy of infancy, or Dravet syndrome. After extensive genetic counseling, the couple decided to terminate the pregnancy at 28 weeks' gestation based on this finding. This case highlights some of the important clinical and ethical considerations in prenatal genetic diagnosis, particularly in the group of patients in which there is no phenotypic evidence in-utero of the incidental finding. The case demonstrates the value of frameworks and guidelines to guide management decisions for both clinicians and patients.

Suicide in frontotemporal dementia and Huntington disease: analysis of family-reported pedigree data and implications for genetic healthcare for asymptomatic relatives.

OBJECTIVE: Genomic testing for early-onset dementia is becoming more accessible, along with predictive testing for at-risk relatives; however, complex counselling issues are important to address. The topic of suicide often has stigma associated, and thoughts or experiences may not be volunteered without prompting. Little has been published with consideration to suicide rates in the context of family experiences and their significance in genetic counselling for relatives of people with Huntington disease and frontotemporal dementia. DESIGN: This study included pedigree information for 267 symptomatic individuals with frontotemporal dementia or Huntington disease, provided via genetic counselling clinics. MAIN OUTCOME MEASURES: Descriptive statistics and suicide rate calculations based on family reported pedigree data. RESULTS: The suicide rate was 2996 per 100,000 compared with the population rate of 10 per 100,000. Approximately one in 15 families reported suicide of an affected family member, and file notes indicated that one in five families had experienced suicide, suicidal thoughts or suicide attempts in one or more affected, unaffected or pre-symptomatic relative. CONCLUSION: Health professional awareness of family experiences, including suicide of a relative, is vital in facilitating client decisions about genetic testing, and in providing adequate psychosocial support during the process of genetic testing and adaption to results.

"It wasn't just for me": Motivations and implications of genetic testing for women at a low risk of hereditary breast and ovarian cancer syndrome.

OBJECTIVE: Genetic testing for hereditary breast and ovarian cancer (HBOC) due to pathogenic variants in BRCA1 or BRCA2 is why most women present to familial cancer centers. Despite being assessed as low risk for HBOC, many women proceed with genetic testing. This study explored the genetic testing experiences of unaffected women at low risk of HBOC to clarify what motivates these women to have testing, and what are the implications of the results. METHODS: A qualitative approach was taken. Participants included women who had genetic testing for HBOC from 2016-2018 at the Parkville Familial Cancer Centre in Melbourne, Australia. In-depth, semi-structured interviews were conducted, and thematic analysis was undertaken on transcripts; transcripts were coded, codes were organized into a hierarchical system of categories/subcategories, and key themes were identified. RESULTS: Analysis of 19 transcripts identified five themes: family underpinned all motivators for HBOC genetic testing; health professionals were influential throughout the process; participants were planning for a positive result; results influenced screening-anxiety and frequency; and negative results gave participants relief in many different ways. The three participants with positive results reported feeling shocked at the results and empowered giving this information to family members. CONCLUSIONS: Women at low HBOC risk may be motivated to seek genetic testing, and access to this is increasingly offered through non-genetic health professionals. Professionals can support clients through genetic testing by recognizing familial experiences, providing accurate information, addressing risk perceptions, and understanding cancer anxiety felt by many women.
