What are the fastest programs to becoming a doctor?

I want to become a Clinical Geneticist. Since that training is another two years after becoming a doctor, I want to know what is the fastest way I can become a doctor. Does anyone know of any programs that fast tract your way into becoming a doctor?|||That is actually a few more years than just 2 after med school as that would be a fellowship on top of a general residency (so more like 5+ years). ANd no one wants to be seen by some one "fast tracked" through med school. Med school is 4 years because there is too much to learn. Don't want you to miss out on something critical.|||You can take extra summer classes to speed your way through the academic process, but other than that, there is no way.
