Genetic Discrimination: Does It Exist, and What Are Its Implications?

Does genetic discrimination exist? Thus far, there have been no cases other than Burlington Northern and maybe a couple of other cases which have been filed by plaintiffs in either federal or state court. Notwithstanding all of the statutes, there haven't been a tremendous amount of charges coming in, people coming to the EEOC (Equal Employment Opportunity Commission), or to respective state agencies and even filing charges. This fact confuses me, because I actually believe that genetic discrimination, as we've been talking about it, is happening more often in the real world than this charge flow would indicate.
