Genetic health professionals and the communication of genetic information in families: Practice during and after a genetic consultation.

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. (c) 2010 Wiley-Liss, Inc.
