I have not currently pursued the field of clinical genetics as a profession because I am just graduating medical school, but I do have clinical experience in the matter as a medical student. It is also a career consideration of mine. However, some basic things are a must: a) Going to college and choosing a major with biology/medical sciences in mind. b) Postgraduate studies are also going to be required if you choose to actively engage in the field of clinical genetics. Most frequently, getting admission and graduating from a medical school is the best bet, after which specialization can be focused on genetic diseases.
