    My husband and I are respectively CT and CC.

    But how about the DAO SNPs? We both are +/+ for one of them.

    rs10156191 Histamine/DAO is DAO I think.

    23andMe says it is ABP1.

    How do you find this histamine gene on 23andMe through Genetic Genie? Does it have a different name? Sorry for another dumb question!

    Click on Gondwanaland's link, and log in to 23andme.com, and it will show you the SNP's for the histamine gene.

    I'm CC. And on the link from @Gondwanaland, I have 11, of which 9 are homozygous. Is this the source of my histamine issues??

    Can you see it on the Genetic Genie print out? I have never logged into 23andMe and not sure what you do?

    Apparently not - I think +/+ MAO-A is enough reason ;)
    Nope.
    Username, password, raw data, then paste rs10156191 into SNP box or ABP1 into gene box.
    Easier if just clicking the link on post #4 and logging in from there.

    rs10156191 TT is pretty common: about 10% of people have that genotype, going up to 40% in some ethnic groups. It's a bit interesting, because according to the research at http://onlinelibrary.wiley.com/doi/10.1111/j.1398-9995.2011.02548.x/full it's associated with down-regulation of the gene, but not associated with histamine intolerance at all.

    It would seem to suggest that the down-regulation of the AOC1 gene caused by rs10156191 TT isn't sufficient to cause any problems. It's not too uncommon for that to happen on various genes.

    Thanks val. Do you base the SNP mainly on prevalence? I'm just wondering because I'm working with someone who is basing their research on the correlation with the SNP's in literature (pub med, etc), and not prevalence.

    9 out 11 seems like quite a bit.

    No, the research is more important. But it's unlikely a genotype for a SNP is causing much mayhem when it's present in 10% of the world's population :p

    Being homozygous or heterozygous doesn't mean anything at all, in itself. You have to look them up to see if there's research saying if they cause a problem or not.

    How about for the other 10 SNP's of ABP1?
