How do I know if I have a gene?
Specifically, I know I have the gene in low activity COMT allele homozygotes. It seems that this combined gene with the use of cannabinoids, while in adolescence (18 years) causes unusual dopamine in the hypothalamus, which could be related to a much greater risk shizophreniform disorders. The COMT gene contains some results from a valine allele activity changes in methionine codon 158, which represents over 95% of the variation population in the activity. Approximately 25% white Caucasian and 3.9% of black and Asian populations are homozygous for the low activity allele (Met158). He is homozygous low-activity form of the gene that has this link. The high activity form heterozygous and homozygous gene present no such risk. So how I can know how the gene that I have?
I would like to start by asking my doctor to refer to a genetic counselor. Who can deal with you as a human being with a greater emphasis on the possibility of going crazy because smoked marijuana as a child, and refer to someone who can be tested and the risk factor in perspective for you. If it were me, working in a research lab as I do, I'll try to find a way to use my budget ethics for PCR, PCR and make my own DNA to see if I was worried. The primers are cheap today. In fact, if it were me, would probably be on the real risks, the strength of research is that you speak, and probably conclude that the risk was very low, there was nothing to do about it at this stage anyway, or both, and just live my life and figure if they have a disorder now, you probably would not. And if you've done, I have to try, but it was an unlikely event.
