Through an examination of the International Haplotype Map , this paper explores some of the ways in which relationships among categories of race and genetic variation are being reconfigured in contemporary genetic research.

In 2000, researchers from the Human Genome Project proclaimed that the initial sequencing of the human genome definitively proved, among other things, that there was no genetic basis for race. The genetic fact that most humans were 99.9% the same at the level of their DNA was widely heralded and circulated in the English-speaking press, especially in the United States. This pronouncement seemed proof that long-term antiracist efforts to de-biologize race were legitimized by scientific findings. Yet, despite the seemingly widespread (...) acceptance of the social construction of race, post-HGP genetic science has seen a substantial shift toward the use of race variables in genetic research and, according to a number of prominent scholars, is re-invoking the specter of earlier forms of racial science in some rather discomfiting ways. During the past seven years, the main thrust of human genetic research, especially in the realm of biomedicine, has shifted from a concern with the 99.9% of the shared genome — what is thought to make humans alike — towards an explicit focus on the 0.1% that constitutes human genetic variation. Here I briefly explore some of the potential implications of the conceptualization and practice of early 21st century genetic variation research, especially as it relates to questions of race.

The role of the major histocompatibility complex (MHC) in mate choice in humans is controversial. Nowadays, the availability of genetic variation data at genomic scales allows for a careful assessment of this question. In 2008, Chaix et al. reported evidence for MHC‐dependent mate choice among European American spouses from the HapMap 2 dataset. Recently, Derti et al. suggested that this observation was not robust. Furthermore, when Derti et al. applied similar analyses to the HapMap 3 European American samples, (...) they did not see a significant effect. Although some of the points raised by Derti et al. are relevant, we disagree with the reported absence of evidence for MHC‐dependent mate choice within the HapMap samples. More precisely, we show here that the MHC dissimilarity among HapMap 3 European American spouses is still extreme in comparison to the rest of the genome, even after multiple testing correction. This finding supports the hypothesis of MHC‐dependent mate choice in some human populations. (shrink)

Public engagement in science and technology has grown in importance as developments in science and technology make increasingly significant impacts on people's lives. Now, efforts to engage publics in social decision-making or consensus-building regarding science and technology involve participation, learning or deliberation opportunities, as well as interactive or coproductive efforts among various sectors in society based on the recognition of scientific activities as a part of social operations - even those performed by scientific communities. We have conducted a community engagement (...) program in the HapMap project, the international human genome program, in Japan since 2002. Consequent upon our various approaches to engage Japanese publics, a range of observations were made, such as that: public engagement is not yet recognized or institutionalized in Japan; there is a wide gap between science and society; and the implications of public engagement in a Japanese context have not been examined enthusiastically, especially from the perspectives of political decision making, social consensus-building or self-determination. In this paper, we provide an overview of public engagement in Japan, and discuss issues and challenges raised by the HapMap community engagement project. We also discuss the implications of public engagement for social decision-making and self-determination, and explore the prospects for public engagement in science and technology in Japan. (shrink)

Many common human traits are believed to be a composite reflection of multiple genetic and non‐genetic factors and the genetic contribution is consequently often difficult to characterise. Recent advances suggest that subtle variation in the regulation of gene expression may contribute to complex human traits. In two reports,1,2 Cheung and colleagues scale up human genetics analysis to an impressive level in a genome‐wide search for the regulators of gene expression. They perform linkage analysis on expression profiles for over 3,500 genes (...) and then employ the HapMap resource3 to take positive findings through to association studies at the genome‐wide level. This work gives new insights into the complexities of gene regulation and the plausibility of genome‐wide study design. BioEssays 28: 968–972, 2006. © 2006 Wiley Periodicals, Inc. (shrink)

This paper explores the intersections between national identity and the production of medical/population genomics in Mexico. The ongoing efforts to construct a Haplotype Map of Mexican genetic diversity offers a unique opportunity to illustrate and analyze the exchange between the historic-political narratives of nationalism, and the material culture of genomic science. Haplotypes are central actants in the search for medically significant SNP’s (single nucleotide polymorphisms), as well as powerful entities involved in the delimitation of ancestry, temporality and variability ( www. (...) class='Hi'>hapmap.org ). By following the circulation of Haplotypes, light is shed on the alignments and discordances between socio-historical and bio-molecular mappings. The analysis is centred on the comparison between the genomic construction of time and ethnicity in the laboratory (through participant observation), and on the public mobilisation of a “Mexican Genome” and its wider political implications. Even though both: the scientific practice and the public discourse on medical/population genomics are traversed by notions of “admixture”, there are important distinctions to be made. In the public realm, the nationalist post-revolutionary ideas of Jose Vasconcelos, as expressed in his Cosmic Race ( 1925 ), still hold sway in the social imaginary. In contrast, admixture is treated as a complex, relative and probabilistic notion in laboratory practices. I argue that the relation between medical/population genomics and national identity is better understood as a process of re-articulation (Fullwiley Social Studies of Science 38:695, 2008 ), rather than coproduction (Reardon 2005 ) of social and natural orders. The evolving process of re-articulation conceals the novelty of medical/population genomics, aligning scientific facts in order to fit the temporal and ethnic grids of “Mestizaje”. But it is precisely the social and political work, that matches the emerging field of population genomics to the pre-existing projects of national identity, what is most revealing in order to understand the multiple and even subtle ways in which population genomics challenges the historical and identitarian frames of a “Mestizo” nation.
