Although professional guidelines recommend against testing minors for adult-onset genetic conditions, the genetic testing of minors for BRCA1/2 alterations has been debated in the literature. To better understand the opinions of BRCA mutation carriers regarding the genetic testing of minors and the cognitive and affective processes underlying these opinions, we interviewed BRCA mutation carriers and their adult offspring who had learned of their parent's BRCA mutation. Semi-structured interviews were conducted with 53 parents and 22 offspring. In response to a closed-ended question, 52% (n = 39) of participants were opposed to the testing of minors. Responses to an open-ended question indicate that many participants (24%, n = 18) feel that testing could be permitted for some minor offspring. Psychological risks and the insufficient maturity of minors were frequent concerns of participants opposed to testing minors. The potential to impact health behaviors was frequently cited as a reason to support the genetic testing of minors. These preliminary results suggest that many BRCA mutation carriers and their adult offspring have concerns about, or are opposed to the genetic testing of minors. However, a significant minority in our study would support testing minors. Greater support for testing among offspring could indicate increasing requests for early genetic diagnosis. Further research is necessary to explore the risks and benefits of providing genetic testing to minors for adult-onset hereditary cancer syndromes in order to inform clinical practice and public policy and to ensure optimal psychosocial and medical outcomes for all members in families at risk for genetically determined disease.
尽管专业指南不建议对未成年人进行成人发病型遗传病检测,但文献中已对未成年人进行BRCA1/2基因改变检测展开了讨论。为了更好地了解BRCA突变携带者对未成年人基因检测的看法以及这些看法背后的认知和情感过程,我们采访了BRCA突变携带者及其已得知父母BRCA突变的成年子女。对53名父母和22名子女进行了半结构式访谈。在回答一个封闭式问题时,52%(n = 39)的参与者反对对未成年人进行检测。对一个开放式问题的回答表明,许多参与者(24%,n = 18)认为可以允许对一些未成年子女进行检测。反对检测未成年人的参与者经常担心心理风险和未成年人不够成熟。影响健康行为的可能性经常被引为支持对未成年人进行基因检测的理由。这些初步结果表明,许多BRCA突变携带者及其成年子女对未成年人基因检测存在担忧或反对。然而,我们研究中有相当一部分人会支持对未成年人进行检测。子女中对检测的更大支持可能表明对早期基因诊断的需求增加。有必要进一步研究为患有成人发病型遗传性癌症综合征的未成年人提供基因检测的风险和益处,以便为临床实践和公共政策提供信息,并确保有遗传疾病风险的家庭中所有成员获得最佳的心理社会和医疗结果。
