The communication of genetic information in families is an important process which can inform family members that they are at risk. However, evidence suggests that at-risk family members are often uninformed. Genetic health professionals have a role to assist consultands to communicate genetic information to their family members. Therefore, the aim of this study was to investigate genetic health professionals' practice with regard to the familial implications of a genetic diagnosis and subsequent family communication. An online survey resulted in 626 responses from genetic health professionals internationally. The results indicated that over 90% of genetic health professionals consistently counsel consultands about the familial implications of a genetic diagnosis during a consultation. Also there were no major differences in practice between clinical geneticists and genetic counselors. An average of 79% of genetic health professionals always send a summary letter to the consultand after a consultation. In contrast, 41% of genetic health professionals never write letters for at-risk family members. Other support is available to consultands after a consultation, but the availability of support relies on consultands and family members acting proactively and seeking out assistance from genetic health professionals for family communication. This may result in family members who are unaware that they are at risk of carrying and/or developing a genetic condition. This study is limited by the self-selection and self-reporting of the respondents' practice.
家族中遗传信息的交流是一个重要的过程,可以告知家庭成员他们有患病风险。然而,有证据表明,高危家庭成员往往不知情。遗传健康专业人员在协助咨询者将遗传信息传达给其家庭成员方面发挥着作用。因此,本研究旨在调查遗传健康专业人员在遗传诊断的家族影响以及随后的家庭沟通方面的实践情况。一项在线调查收到了来自国际遗传健康专业人员的 626 份回复。结果表明,超过 90%的遗传健康专业人员在咨询期间始终就遗传诊断的家族影响向咨询者提供建议。临床遗传学家和遗传咨询师之间的实践也没有重大差异。平均有 79%的遗传健康专业人员在咨询后会给咨询者寄一份总结信。相比之下,只有 41%的遗传健康专业人员从不为高危家庭成员写信。咨询者在咨询后还可以获得其他支持,但支持的可用性取决于咨询者和家庭成员是否积极主动地寻求遗传健康专业人员的帮助进行家庭沟通。这可能导致一些家庭成员不知道自己有携带和/或患上遗传疾病的风险。本研究受到受访者实践的自我选择和自我报告的限制。
