this is a nice scenario, but... you're patient is NOT going to be able to run out and get her genome sequenced (and as a genetic counselor you are not going to be able to order this test and insurance cover it). it does NOT cost about $1K for a clinic patient to get their genome sequenced right now. not even close. there is a contest right now for scientists to develop a technology that will allow sequencing of a genome for $1000K. No one has done it yet. And even once someone comes up with the technology, that doesn't mean that it costs $1K to the patient. Someone has to produce the kit, deal with getting it FDA approved, figure out a way to do it on a LARGE scale production, how to deliver the results, how to store them, accuracy-what about false positives and negatives and the liability this entails? etc., etc. while it is true that genetic testing will in our lifetimes become a reality there are a lot of hurdles: scientifically, economically and ethically that will come into play before the genetic counselor is writing orders for every patient who walks through the door to have their genome sequenced. while i think there is a need for genetic counselors, especially in taking the time-which many doctors don't have, to explain the risk of transmission for parents with risk alleles who are trying to conceive, the scenario isn't quite as peaches and cream as you suggest. you seem to knock on pre-meds for glamorizing medicine, but you might want to do some reality check as well about your chosen career.
There is a lot of responsibility and a lot of emotions that can take place during a genetic counseling session. For instance, lets look at the following example.
A 35 year old female calls on the phone wanting to know if she inherited her breast cancer from her mother and if she can pass it on to a child. So the counselor recommends that the person come into the clinic to have a counseling session done. An assessment has to be done regarding if a test for BRCA1 and 2 should be done (will insurance cover the cost) and if the patient is psychological stable enough to handle a positive test. Maybe the BRCA gene is not the cause of her breast cancer. Maybe it was the ATM gene leading to her breast cancer. So after a family history is done, the counselor finds out that the patient has an increased risk of breast cancer because of her ethnicity.
It turns out that the 35 year old female is single but wants to marry but has had her breast removed to help prevent her breast cancer from coming back. So now the patient finds out that she is positive for a mutation in the BRCA1 gene that can leads to breast cancer and the counselor describes how the mutation can lead to developing breast cancer and explains that there is a 50 percent chance of her passing on the gene to a child for developing breast cancer. However, even if her child was to develop breast cancer it might not actually be a result of the mutation she inherited. Since there are several ways a person can develop breast cancer, the counselor can explain that even if the child was to be tested and found positive to have the mutation that the mother passed on, does not mean that the child will develop breast cancer. Even though the risk of developing breast cancer is higher. Therefore, when the child gets to be around 35 or so years old, the child should be getting checked for breast cancer. So now comes into play personalized medicine. Lets say the child was found positive for the mutation leading to breast cancer and latter develops is at age 37, the child already has her genome screened because the counselor recommend that the parents child have her genome screened so effective therapy can be done if her child were to develop breast cancer. Thus, if the breast cancer is found early, then there is a better chance of the child not getting to ill because of better therapy that COULD result from her genome being sequenced (only cost $1,000 these days and will only get cheaper) and cancer being found early and already have a positive test for the mutation.
So now comes the emotions of the parent because she has had her breast removed and still wants to have a family and having a 50 percent chance her children developing breast cancer as well.
This is only a small portion of what the counseling session will entail.
I really enjoy this type of work. That is why Im becoming a genetic counselor. Im not interested in the other type of medical care (i.e., repairing a broken bone, doing heart surgery, putting a balloon in, and so forth Im not interested in doing that type of work). I would rather have a role in helping the clinical geneticist in the management of the genetic disease and do counseling. I really enjoy this and I am really excited for having the chance to do it.
My advice is to have someone start a RT forum and spend your time there. There is no need to keep bashing me for what I like.
