Genetics research often pushes the boundaries of science, and by the far-reaching nature of genetic information, pushes us out of our comfort zones to consider new psychosocial, ethical, and legal scenarios. Conducting genetic testing on children arguably pushes our boundaries most. Yet, there can be medical benefits for some children, who may then be offered tailored medical care to match their risks. Children can also be indirectly affected by genetic testing, when they learn genetic information about themselves because a family member has had a genetic test. Read More

Should a patient have a right not to know genetic information about him or herself?

By Benjamin E. Berkman, JD, MPH

While promising to eventually revolutionize medicine, the capacity to cheaply and quickly generate an individual’s entire genome has not been without controversy.  Producing information on this scale seems to violate some of the accepted norms governing how to practice medicine, norms that evolved during the early years of genetic testing when a targeted paradigm dominated.  One of these widely accepted norms was that an individual had a right not to know (“RNTK”) genetic information about him or herself.  Prompted by evolving professional practice guidelines, the RNTK has become a highly controversial topic.  The medical community and bioethicists are actively engaged in a contentious debate about the extent to which individual choice should play a role (if at all) in determining which clinically significant findings are returned.

In a recent paper published in Genetics in Medicine, my coauthors and I provide some data that illuminates this and other issues. Our survey of 800 IRB members and staff about their views on incidental findings demonstrates how malleable views on the RNTK can be.  Respondents were first asked about the RNTK in the abstract: “Do research participants have a right not to know their own genetic information?  In other words, would it be acceptable for them to choose not to receive any GIFs?”  An overwhelming majority (96%) endorsed the right not-to-know.  But when asked about a case where a specific patient has chosen not to receive clinically beneficial incidental findings, only 35% indicated that the individual’s RNTK should definitely be respected, and 28% said that they would probably honor the request not to know.  Interestingly, the percentage of respondents who indicated that they do not support the RNTK increased from 2% at baseline to 26% when presented with the specific case.  The percentage of people who are unsure similarly jumps, from 1% to 11%.

How broad can consent be?

By Nanibaa’ A. Garrison, Ellen Wright Clayton and Ingrid A. Holm

Based on today’s publication of the paper A systematic literature review of individuals’ perspectives on broad consent and data sharing in the United States in Genetics in Medicine. 

The recent Notice of Proposed Rule Making (NPRM) issued by the Office of Human Research Protections proposes to require researchers to obtain informed consent from virtually every patient and research participant for use of biospecimens for research. The proposed regulations also permit obtaining broad consent for future uses, without any IRB oversight unless individual results are going to be returned so long as an elaborate consent form is signed. The NIH Genomic Data Sharing Policy, which went into effect earlier this year, requires almost all investigators who receive NIH funding to seek broad consent from participants to allow their data to be shared with other investigators. Thus, in a short period of time, two major policies promoted broad consent for biobank research, changes in the practice of recruiting participants for research that make us take notice. They also raise new questions, including: What do research participants think about having their biospecimens and data shared, and about giving broad consent to do so?

Who is comfortable with Broad Consent?
The Electronic Medical Records and Genomics (eMERGE) Network’s Consent, Education, Regulation, and Consultation (CERC) working group set out to find some answers. As a part of this effort, we conducted a systematic review, which revealed that males, whites, older individuals, and more affluent individuals are generally pretty comfortable with broad consent that can be found here. By contrast, Asian and African American individuals are less comfortable with broad consent. Will these different levels of concern create a divide between those who will and will not participate? The consequences of lack of participation are clear – we will know less about how genetic variation in groups that do not take part affects health and less about how to provide optimal care. Read More
