The following information was provided to me from another non Mwo member
"Hey Coalfire,
I'm not a geneticist so forgive me if I use the wrong terminology, but the gene associated with nal response is located at Rs1799971 and is called OPRM1. The possible genotypes are AA, AG, and GG. AA is normal. AGs have a better chance of responding to nal than AAs. And GGs have an even better chance of responding to nal, but have an increased likelihood of developing alcoholism, and an increased aversion to social rejection. There is a much more in depth description of this at Rs1799971 - SNPedia
Here is a chart from the above website of the percentage of each genotype in different sample populations.

Orange is AA, Green, AG and Blue GG. Most on this board will be interested in CEU, which is a sampling of a western and northern European population. I probably relate most to HCB, which is a Chinese population (I'm Vietnamese) Most people are AA and that group has about a 55% positive nal response. If you have at least one G then your chances go up to 87%. You can see the GGs are on average, less than 10% of the population. I am GG."
If anyone is interested in this test you can have it done here https://www.23andme.com/
It is a saliva home test kit which costs $199 or Euro 142 approx.
