Incorporating multiracial and multiethnic experiences into genetic counseling practice and research: A necessary opportunity.

Abstract

The conflation of race and genetic ancestry can have harmful consequences. Biological conceptualizations of race have long been used to justify inequities and distract from social structures that afford opportunities to some that are unjustly denied to others. Despite recent efforts within the scientific community to distinguish between the sociopolitical constructs of race and ethnicity and the biological constructs of genetic ancestry and genetic similarity, their conflation continues to influence genomic research and its translation into clinical care. One overlooked aspect of this problematic conflation is the extent to which discrete monoracial and monoethnic categorization systems persist and perpetuate unequal benefit-sharing in the clinical translation of genomic technologies. In genetic service delivery, reliance on discrete racial and ethnic categories undermines the clinical translation of genomic technologies for large segments of the global population. For multiracial and multiethnic individuals, who have complex identities that defy discrete categorization systems, the potential benefits of genomic discoveries are especially elusive. Scholars have recently begun to call for the inclusion of multiracial, multiethnic, and admixed individuals in race, ethnicity, and ancestry frameworks in genetics and genomics. However, little work has been done to explore and address the unique challenges and opportunities posed by multiracial/multiethnic individuals in genetic counseling specifically. We discuss how conceptualizing diversity along discrete racial and ethnic lines perpetuates inequitable patient care and limits efforts to increase inclusion and belonging within genetic counseling. Moreover, we argue that ongoing efforts to mitigate racial inequity must actively challenge the paradigm of monoracial and monoethnic categories to accomplish their goal.
