“…Scientific practices involved in research on race and ethnicity in health and genomics have been shown to be situated in and shaped by various specific national, sociopolitical, and historical contexts (Hinterberger, 2012;Epstein, 2010;Tsai, 2010;Olarte Sierra and Díaz Del Castillo Herná ndez, 2014). These national, sociopolitical, and historical contexts shape the ways in which ethnicity and race are enacted in research by prescribing, for example, the (official) categories which must be used in research -a process referred to as ''categorical alignment'' (Epstein, 2007) -or by defining which groups are and are not considered to be ethnic and racial minorities (Gissis, 2008;Helberg-Proctor et al, 2016, 2017Proctor et al, 2011). Scientific practices involved in research on race and ethnicity in health and genomics have also been shown to be situated in the specific dynamics of a ''research situation'' (Shim et al, 2014), whereby dynamics unique to a specific research situation, such as the availability of data and sufficient sample sizes per ethnic and or racial group and the specific aims of a project, shape the manner in which ethnicity and race are enacted (Shim et al, 2014;Helberg-Proctor et al, 2016).…”
