Still Chasing Ghosts: A New Genetic Methodology Will Not Find the “Missing Heritability”

Search for the missing heritability

By Evan Charney, Duke Institute for Brain Science, Duke University

One of the hopes and promises of the Human Genome Sequencing Project was that it would revolutionize the understanding, diagnosis, and treatment of most human disorders. It would do this by uncovering the supposed “genetic bases” of human behavior. With a few exceptions, however, the search for common gene variants -“polymorphisms” – associated with common diseases has borne little fruit. And when such associations have been found the polymorphisms seem to have little predictive value and do little to advance our understanding of the causes of disease. In a 2012 study, for example, researchers found that incorporating genetic information did not improve doctors’ ability to predict disease risk for breast cancer, Type 2 diabetes, and rheumatoid arthritis [1]. … Continue Reading

Science and Social Control: Political Paralysis and the Genetics Agenda

NIH_1crop2

By Jonathan Latham, PhD (Originally posted July 31st and lost after a DDOS (electronic) attack).

Variations in individual “educational attainment” (essentially, whether students complete high school or college) cannot be attributed to inherited genetic differences. That is the finding of a new study reported in Science magazine (Rietveld et al. 2013). According to this research, fully 98% of all variation in educational attainment is accounted for by factors other than a person’s simple genetic makeup.

This implies that most of student success is a consequence of potentially alterable social or environmental factors. This is an important and perhaps surprising observation, of high interest to parents, teachers, and policymakers alike; but it did not make the headlines.

The likely reason is that the authors of the study failed to mention the 98% figure in the title, or in the summary. Nor was it mentioned in the accompanying press release. … Continue Reading

‘Phantom Heritability’ Indicates Poor Predictive Value of Gene Tests

Last week, a paper on “phantom heritability” was published by a research group led by Eric Lander, one of the leading contributors to understanding the implications of the Human Genome Project (HGP) for common, complex diseases such as heart disease and cancer (1). The paper has created excitement amongst scientists who have been critical of the claims made for the likely impacts of the HGP on health and medicine. This is not because the paper makes a startling new discovery, but because it is an important step towards recognition of these long standing criticisms. … Continue Reading

23andMe disproves its own business model

July 7, 2011 Health, News 2 Comments

Jonathan Latham

Online gene testing company 23andMe last week published its first genetic research study into Parkinson’s Disease. The study was funded by the participants (many of whom are customers of 23andMe), the company itself, and Google-founder Sergei Brin, who is married to 23andMe’s CEO and founder, Anne Wojcicki (1). Wojcicki is also personally subsidising the company and is a co-author on the paper.

23andMe’s study shows that two new genes it has discovered, plus all known existing genes linked to the disease, are not much better than random selection for predicting who will get Parkinson’s Disease. … Continue Reading

The Great DNA Data Deficit: Are Genes for Disease a Mirage?

Are Genes for Disease a Mirage?

Jonathan Latham and Allison Wilson

Just before his appointment as head of the US National Institutes of Health (NIH), Francis Collins, the most prominent medical geneticist of our time, had his own genome scanned for disease susceptibility genes. He had decided, so he said, that the technology of personalised genomics was finally mature enough to yield meaningful results. Indeed, the outcome of his scan inspired The Language of Life, his recent book which urges every individual to do the same and secure their place on the personalised genomics bandwagon.

Neoliberal Ebola: The Agroeconomic Origins of the Ebola Outbreak

Guinea Forest Region in 2014

by Rob Wallace The notion of a neoliberal Ebola is so beyond the pale as to send leading lights in ecology and health into apoplectic fits. Here’s one of bestseller David Quammen’s five tweets denouncing my hypothesis that neoliberalism drove the emergence of Ebola in West Africa. I’m an “addled …

Ruthless Power and Deleterious Politics: From DDT to Roundup

DDT, Time Magazine, 1947

By Evaggelos Vallianatos Morton Biskind, a physician from Westport, Connecticut, was a courageous man. At the peak of the cold war, in 1953, he complained of maladies afflicting both domestic animals and people for the first time. He concluded that the popular insect poison DDT was the agent of their …

Monsanto’s Worst Fear May Be Coming True

Chipotle Mexican Grill

by Jonathan Latham, PhD The decision of the Chipotle restaurant chain to make its product lines GMO-free is not most people’s idea of a world-historic event. Especially since Chipotle, by US standards, is not a huge operation. A clear sign that the move is significant, however, is that Chipotle’s decision …

Anthropocene Boosters and the Attack on Wilderness Conservation

White Cloud Mountains, Idaho, George Wuerthner

by George Wuerthner A growing debate has serious consequences for our collective relationship to Nature. Beginning perhaps twenty years ago, a number of academics in disciplines such as history, anthropology, and geography, began to question whether there was any tangible wilderness or wild lands left on Earth. These academics, and …
