amazing thread. when i saw the dopamine and alcohol words together in the title, i knew its going to be interesting and boy what a trip it is to read it.
chadwick, i find it amazing how when you started this thread you were still figuring out whats wrong with you and by the end of the thread, not only did you find out and fix yourself, now you are like a teacher to the rest of us! which is amazing. most people start threads and cry all the time asking for answers and usually people cannot give them any. i have noticed no thread ever gives a topic starter their best solutions EVER but its like a road down the thread to find out whats best yourself and you suprised me to do just that contrary to other people on this forum. i must say, you are a pretty smart guy, except mentioning the defects in genes associated with dopamine, did you also see any expression in genes involved in intelligence?
but i have to ask this, its main reason i reply though i love the thread, im not sure i have the same problem to follow your regime and im not sure what problem i have anyway so this is why i reply now to ask this; if order the gene test from 23andMe, how much do they really tell you and explain in detail to you whats wrong and right with you ? i have never done this gene test, i have no clue how to read it! and you are smart enough to have figured it out by yourself without them telling you i assume ? i have to take this test but if they cannot help me with information, ill waste money on something i dont even really understand at all. but i assume you can read those tests and help me out ? i dunno if you self taught yourself all that biochemistry and knowledge on genetical problems, but you know what you are talking about so i put trust in you. perhaps you even have a job related to this ?
anyway any help much appreciated!!
I took me two years of medical school as well as a lot of thinking and reading on my own to figure out what my own problem really was. And now than I've done that and learned how to treat it, I can tell you that it was so, so worth it. I changed my life for the better, and I would be glad if I could help other people with similar problems to do the same.
I'm curious about how you see your problem subjectively - is it lack of motivation, depression, fatigue, or how would you describe them?
23and me will tell you some basic information about disease risks, but if you want to find out about you're genes relating to neurotransmission I'm afraid you'll have to download the raw data and analyze it yourself.
The easiest way to do this is to use Promethease (
https://promethease....ondemandlicense) which is an easy analytic tool, GeneticGenie Methylation Analysis (
https://geneticgenie...ation-analysis/) which will give some info about genes relating to methylation, and SNPedia (
http://www.snpedia.c...dex.php/SNPedia) which is a wiki-site that explains various genes. The easies ways to see your polymorphisms (gene variations) is to download your raw data from 23andme and upload it to Promethease, and then download the files you get from them. In the "report_ui2.html" file you can then search for certain SNPs (point mutations), that have names like Rs123456 and so on below. For the genes with many important SNPs you can just search for the gene name in Promethease and it will tell you if it finds something unusual.
These are the genes and SNPs I believe are the most important to look at when it comes to dopamine:
MTHFR - A gene involved in producing the active form of folate, which is needed to make several neurotransmitters.
Rs1801133 aka C677T. C is good to have, T is bad.
Rs1801131 aka A1298C. A is good, T is bad.
DHFR - Another gene involved in folate metabolism AND BH4 recycling. Not quite as important but still relevant. It's not know which SNPs are important here. Personally I'm homozygous
Rs1650697 which is somewhat uncommon. C is good to have here, and T is bad.
GCH1 - Involved directly in BH4 synthesis. Many SNPs that are important, see
http://snpedia.com/index.php/GCH1.
PCBD1 - Involved in BH4 synthesis. Many SNPs, see
http://snpedia.com/index.php/PCBD1.
PTS - Involved in BH4 synthesis. Many SNPs, see
http://snpedia.com/index.php/PTS.
QDPR (aka DHPR) - Involved in BH4 synthesis. This enzymes uses NADH, which I believe is the reason that NADH can raise BH4. Many SNPs, see
http://snpedia.com/index.php/QDPR.
SPR - Involved in BH4 synthesis. Many SNPs, see
http://snpedia.com/index.php/SPR.
TH (tyrosine hydroxylase) - Converts tyrosine to L-DOPA, which then is used to make dopamine. TH is an iron-containing enzyme, which is the reason that iron deficiency can lead to lower dopamine levels. Many importants SNPs, see
http://snpedia.com/index.php/THDDC (aka AADC, dopa decarboxylase) - Turns L-DOPA into dopamine, and 5-HTP into serotonin. Several important SNPs, see
http://www.snpedia.com/index.php/DDC.
COMT - Breaks down dopamine and other neurotransmitters.
Rs4680 aka the warrior/worrier SNP. The Met version (A) will give you lower COMT activity and therefore more dopamine. This will lead to higher pleasure response and higher extraversion, but also lower threshold for stress. The Val version (G) will give you higher COMT activity and therefore less dopamine. This will lead to lower pleasure response, lower extraversion but also higher threshold for stress. Val will make you calm and collected while Met will make you motivated and outgoing.
MAO - Breaks down dopamine and several other neurotransmitters.
Rs6323 - G will lead to higher enzyme activity and lower dopamine, and T to lower activity and higher dopamine.
DAT (aka SLC6A3, dopamine transporter) - removes dopamine from the synapse so it can't bind its receptors.
Rs27072 is onvolved in alcohol withdrawal as well as ADHD. C increases risk for ADHD and alcohol withdrawal, T lowers it.
DRD1 (dopamine receptor D1) - Involved in neuronal development and various behavioural responses. Several semi-important SNPs, see
http://www.snpedia.com/index.php/DRD1.
DRD2 (dopamine receptor D2) - Involved in social functioning, extraversion and social status. Low D2 binding
correlate with social phobia.
Rs1800497 aka Taq1a polymorphism. C is good to have, T is bad.
DRD3 (dopamine receptor D3) - Low activation is involved in cognitive problems and depression. See
http://www.snpedia.com/index.php/DRD3.
DRD4 (dopamine receptor D4) - Links to lots of psychiatric conditions, including ADHD.
Rs1800955 is linked to personality. T is the normal variant, and C increases novelty seeking.
DRD5 (dopamine receptor D5)http://en.wikipedia.org/wiki/DRD5 - Not sure if it's involved in anything unique.
See http://en.wikipedia.org/wiki/DRD5.
If you're main focus is how low dopamine connects to social phobia or lack of social drive/motivation, I believe that MTHFR, DHFR, MAO, COMT and DRD2 are the most important. And yeah - I personally have bad versions of them all.
