ES/WGS 'Get Personal'

In the American Journal of Medical Genetics this week, the University of Washington's Holly Tabor and colleagues discuss how they say "exome and whole-genome sequencing challenge the ethical framework of human genetics research," provide "broad guidance about interim ways to contend with these issues, and make broad recommendations for areas for novel resource and policy development." Among the ethical challenges the authors discuss, Tabor et al. say that exome and whole-genome sequencing raise unique issues regarding informed consent. These include:


▪ whether the aims of ES/WGS research are different from more conventional genetic research
▪ if the risks and benefits of ES/WGS are unique and therefore require explanation in order for participants to make informed decisions about participation
▪ whether participants should be told specifically about ES/WGS during informed consent in order to maintain transparency and trust in the research enterprise

Tabor and her colleagues say that because "the last few years have witnessed a shift toward increased sharing of human genetic and phenotypic data as a means to facilitate and accelerate genomics research," use of exome and whole-genome sequencing in human research poses data-sharing challenges. Compared with genome-wide association studies, the authors say it'd be ostensibly simpler to identify research participants involved in studies in which "individuals, families, and populations will be sequenced to discover genes for both rare monogenic disorders and common, complex diseases." This, they add, necessitates that researchers "assess the specific risk of identifying study participants from ES/WGS data," especially when data found might be stigmatizing.

Finally, Tabor and her colleagues discuss the challenges of returning exome and whole-genome sequencing results to research participants, a problem that they say is compounded since "the details of how 'clinically utility' and 'actionable' are defined, and by whom, remain under dispute."

The Scan

LINE-1 Linked to Premature Aging Conditions

Researchers report in Science Translational Medicine that the accumulation of LINE-1 RNA contributes to premature aging conditions and that symptoms can be improved by targeting them.

Team Presents Cattle Genotype-Tissue Expression Atlas

Using RNA sequences representing thousands of cattle samples, researchers looked at relationships between cattle genotype and tissue expression in Nature Genetics.

Researchers Map Recombination in Khoe-San Population

With whole-genome sequences for dozens of individuals from the Nama population, researchers saw in Genome Biology fine-scale recombination patterns that clustered outside of other populations.

Myotonic Dystrophy Repeat Detected in Family Genome Sequencing Analysis

While sequencing individuals from a multi-generation family, researchers identified a myotonic dystrophy type 2-related short tandem repeat in the European Journal of Human Genetics.
