There are many different genetic cluster for each of the commonly used 'races' and thus there isn't a one to one match. Thus there is a difference.
You are correct when you mention diseases that effect certain groups of people, but what the latest genetic reseach shows is these do NOT line up by what one defines as 'race' but by these more specific genetic clusters.
Take the sickle cell disease. Now the common understanding, even by doctors, is that this is a disease that effects 'blacks' but that really isn't true. When DNA is used to classify people into genetic clusters and since 'blacks' fall into many different clusters, some of these clusters have a lot higher rate of sickle cell and others do NOT.
This has major ramifications in treating the disease. Instead of just giving every 'black' the same diagnostic test just because they look 'black' they can use their DNA to target those individuals in the specific genetic cluster that are most likely to get the disease.
Very soon doctors will have a DNA profile for all their patients and these will pay a major role in how a doctor treats a patient (e.g. the odds one will get a heart attack, stroke, cancer, etc...).
Now I agree that in areas like schools this isn't going to happen. But if one is going to do a research study, it isn't difficult to ask those in this study to provide a DNA sample and to use that in the study.
And if based on this approach those culturally are defined as black do worst than so be it. At least then we will have something that the NAACP cannot say is a bias study!
