For centuries, the colonial governments used a combination of race and ethnic characteristics to subjugate and control people of color, and scientists of the day provided evidence of the “natural order of things” to support national policies of domination, segregation and control. There have been many examples of events in the past 70 years to suggest that achievements by ethnic peoples are not genetically determined and that race and ethnicity are merely terms to describe external features, language, culture, social mores and folklore. BiDil was the first drug in this country approved by the FDA for use in a single “race” after a clinical trial that enrolled only members of that race. Thus arose the question of the efficacy of doing race-based research in humans. In order for this kind of research to have any scientific basis, each individually defined or self-declared race would have to have a 100% pure gene pool, and the data show that the gene pool among whites, blacks and Hispanics in America is very heterogeneous. This makes for far greater similarities among U.S. citizens than any perceived differences, and genomic science has failed to support the concept of racial categories in medicine.Scientists involved with the first mapping of the human genome have noted that there is no basis in the genetic code for race. That being the case, there appears to be no justification for race-based research among human beings.

Although the United States has experienced enormous improvements in its healthcare system over the past half-century, there are still widening disparities in most disease processes between whites and blacks/Hispanics.’ There has been much debate as to how these disparities can be eliminated, but simple, logical programs that could be tailored to specific minority communities in different geographical locations have not proven to be practical for a variety of reasons. To be sure, disparities in healthcare, like anything else, are a function of a variety of factors, including education, environment, income and culture, among others. Race and ethnicity are important determinants of some of these functions, thus raising the question as to whether these parameters may, in fact, be determinants of outcome in some of these disease processes based upon genetics as well as the aforementioned risk factors.

Modern-day science has amassed enough evidence to suggest that there is very little biological difference between the various races. In order for race-based research to have any scientific basis, each individually defined or self-declared race would have to have a 100% pure and homogeneous gene pool. Some racial and ethnic groups have a very heterogeneous gene pool, such as whites and Hispanics. The same scientific data show that approximately 80% of American blacks have some degree of white ancestry, and although not so nearly well publicized is the fact that many whites also have black and Hispanic ancestry. This would make for far greater similarities in the U.S. black/white gene pool than any perceived differences, and genomic science has failed to support the concept of racial categories in medicine and further purports that there is more genetic diversity within a “racial cohort” than any differences between two such cohorts.” Craig Venter, who helped produce the first map of the human genome, noted that there is no basis in the genetic code for race.’ That being the case, race then becomes rather meaningless in scientific research. This would obviously include race-based pharmaceutical research that resulted in the drug BiDil. This is not to be confused with the fact that race indeed affects both access and outcomes in our healthcare system, as it most certainly does. Even black medical professionals do not enjoy the same access to highly specialized services as their white counterparts, such as coronary artery bypass grafting, but the basis is not biological and by extension, not genetically determined…
