Orphanet Journal of Rare Diseases | Reproductive Decisions of NF1 Patients: The Interplay of Desire, Responsibility, and Moral Dilemma

Recommend:

This article systematically explores the psychological and ethical conflicts faced by NF1 patients when making reproductive decisions, revealing the critical role of genetic risk, personal health considerations, and medical advice in decision-making. It provides a valuable sociomedical perspective for reproductive counseling for individuals with rare diseases.

 

Literature Overview
The article, titled “To have children or not? Between desire, responsibility, luck, and guilt: reproductive decision-making in individuals with neurofibromatosis type 1,” published in Orphanet Journal of Rare Diseases, reviews and summarizes the complex psychological and ethical dilemmas experienced by individuals with neurofibromatosis type 1 (NF1) in reproductive decision-making. Based on in-depth interviews with 93 Polish NF1 patients, the study analyzes the main influencing factors in decisions regarding whether to have children or continue childbearing, including perceptions of genetic risk, personal health status, medical advice, and concerns about offspring health. The article also emphasizes the patients' deep understanding of disease phenotypic variability and its impact on family planning.

Background Knowledge
Neurofibromatosis type 1 (NF1) is a rare autosomal dominant disorder caused by mutations in the NF1 gene, which encodes neurofibromin, a protein that regulates the RAS-MAPK signaling pathway. Dysregulation of this pathway leads to a wide range of clinical manifestations, including café-au-lait spots, neurofibromas, skeletal abnormalities, and optic pathway gliomas. NF1 is inherited in an autosomal dominant pattern, with a 50% chance that an affected parent will pass the mutation to their child. The severity of the disease can vary greatly, even within the same family, and the Riccardi scale categorizes the severity into four levels. Despite the availability of prenatal and preimplantation genetic testing, many individuals with NF1 face profound emotional and ethical challenges when making decisions about parenthood. This study is among the few that explore these decisions from a sociomedical perspective, shedding light on the lived experience of NF1 and its impact on reproductive autonomy, guilt, and intergenerational responsibility. The findings highlight the importance of early diagnosis, access to accurate genetic counseling, and psychological support for individuals with NF1 considering parenthood.

Research Methods and Experiment
This study employed a qualitative research design grounded in constructivist grounded theory, conducting in-depth interviews with 93 individuals with NF1 (74% female), of which 58% were single and 49% already had children. The interviews focused on participants' subjective experiences regarding reproductive planning, including decisions to have or not have children, the ethical and emotional conflicts behind these decisions, and the influence of medical advice on family planning. Data were collected between August 2020 and April 2021, with interviews conducted via phone or online meetings in participants' homes, lasting an average of 90 minutes. All interviews were audio-recorded and transcribed, and analyzed using three-step coding (line-by-line coding, focused coding, and theoretical coding) to extract core themes.

Key Findings and Perspectives

• 50% genetic risk is a major factor influencing reproductive decisions among NF1 patients, with some choosing not to have children to avoid passing the mutation to their offspring, which they perceive as a moral responsibility.
• Some women choose not to reproduce due to personal health risks, such as worsening symptoms during pregnancy or a history of heart surgery, viewing this as a protective measure for their own life.
• Medical advice significantly impacts decision-making, sometimes overriding personal reproductive desires, especially in patients with severe symptoms or strong family disease history.
• Parents who already have children with NF1 show significant psychological burden when considering having another child, fearing resentment from their children and being unable to cope with the consequences of another pregnancy.
• Some participants reported strong feelings of guilt after their child was diagnosed with NF1, believing they might have avoided parenthood had they known about their own diagnosis earlier.
• The study reveals that reproductive decisions among NF1 patients often involve conflicts between self-identity, health responsibility, and ethical obligation. Reproduction is not only a personal choice but also a symbol of identity and responsibility.
• Despite genetic anxiety, some individuals persist in their reproductive intentions, using assisted reproductive technologies (e.g., PGT) to reduce genetic risk or relying on partner support to overcome psychological barriers.

Significance and Future Directions
This study provides a deep sociomedical perspective on reproductive decision-making among NF1 patients, emphasizing the importance of psychological support and personalized genetic counseling. Future research may further explore decision-making differences among NF1 patients in different cultural contexts and develop psychological interventions to help them make more rational reproductive choices.

Conclusion
This study demonstrates that reproductive decisions among NF1 patients are influenced by multiple factors, including genetic risk, personal health, medical advice, and ethical responsibility. Some individuals choose not to have children out of fear of passing on the condition, viewing this as a responsible decision, while others persist in their reproductive intentions with partner support or medical interventions. Notably, some participants only discovered their NF1 diagnosis after their child was diagnosed, leading to profound feelings of guilt and psychological burden. Therefore, early genetic testing, genetic counseling, and psychological support are crucial for helping NF1 individuals make informed reproductive decisions aligned with their values. The study calls on healthcare professionals to avoid one-sided narratives of risk when discussing genetic concerns and instead encourage patients to explore their own agency and life goals.
