This study is being conducted to learn more about family communication of genetic risk information. Semi-structured interviews lasting up to one hour will be conducted with three populations: parent/child pairs at risk for Huntington's Disease, parent/child pairs at risk for hereditary cancer, and genetic counselors.

The investigators currently lack an adequate understanding of how parents and children feel about genetic risk/status, how it is communicated, and how it influences wellbeing and family relationships. This understanding is vital in order for genetic counselors and other health care professionals to provide the best guidance possible to families. However, little research has been conducted on the impact of genetic risk information or testing on children from the perspective of the child. The research proposed here is uniquely positioned to help fill this gap.

For this study, the investigators will interview 15-20 parent/child pairs who are at risk for Huntington's Disease (HD), 15-20 parent/child pairs who are at risk for hereditary cancer, and 15-20 certified genetic counselors. Interviews will last no more than one hour and will be conducted at a time and place that is convenient for the participant. The investigators will offer participants a choice of conducting the interview in a private conference room at the Berman Institute of Bioethics, or remotely by Skype or telephone. Parents and children will be interviewed separately. Parents will be asked about the decision process behind how and when they disclosed genetic information to their child, style of family communication, advice for other parents in similar situations, and other questions related to the subject of communication of genetic information to minors. Children will be asked about their experience learning genetic risk information, style of family communication, how they felt, advice for other kids in similar situations, and other questions related to the subject of communication of genetic information to minors.

Inclusion Criteria:

• Parents at-risk for HD, affected by HD, or be the spouse/partner of someone living who at risk for or affected by HD.
• Parents who have or have had a diagnosis of hereditary cancer, or the spouse/partner of someone living who has or has had had a diagnosis of hereditary cancer.
• Children ages 15-17 who are at risk for either HD or hereditary cancer

Exclusion Criteria:

• Parents and children who have not yet communicated about genetic risk
• Children younger than age 15

The study population will include individuals who reside in the USA, speak English, and are able to participate in one interview either in person, via phone, or via Skype.
