The health care needs of racial and ethnic groups are similar in virtually all respects, but in some cases diseases or drug responsiveness based on genotypic variation may correlate with race or ethnicity. Knowing that those variations exist, when to test for them, and when to take them into account in clinical decisions will require research directed at uncovering genotypic differences that correlate with race or ethnicity. 

Although it may often be permissible for health reasons to classify patients by race or ethnicity, some uses of race in the health area would not be acceptable, for example, unfounded negative stereotypes about the need of African Americans for pain relief or other medical procedures. (Institute of Medicine, 2002). The impermissibility of some uses of race, however, does not negate their permissibility in other areas. As we will see, the impermissible uses are more likely to involve health delivery issues, are less closely tied to the health effects of biological or genotypic differences, and are only indirectly connected with minority health care. In addition, another person is often excluded or hurt by the racial classification at issue.

In an effort to find a biological process that may identify a specific genotype, differences in various enzymes (e.g., monoamine oxidase, dopamine b-hydroxylase, and catechol-O-methyltransferase) have also been investigated.

There are no conclusive evidences between genotype and phenotype, although some phenotype or genotype differences are detected in the population.
