A study of 104,268 single nucleotide polymorphisms (SNPs) from 240 participants in the Collaborative Study on the Genetics of Alcoholism (COGA) has revealed 51 clusters of genetic variations that are associated with alcohol addiction. The chromosomal locations highlighted involve genes or areas near genes that play a role in cell signaling, gene regulation, and development, including the gene for cadherin 13, previously linked to methamphetamine abuse.

Sangita: You’re welcome.
thanks for the information its very helpful
Wow – thanks Hsien… that is a wonderful compliment!
Mark:
At this point, genetic info isn’t half as useful as the kind you provide at A Dozen Steps. 
Hmmm… so my “single nucleotide polymorphisms” are genetically clustered… – yep! Got it! But I can’t say what I’d like to, lol. Think – cluster &
Very interesting Hsien. “Single nucleotide polymorphisms” would never ever have entered my thoughts about it
I believe I’ll stick with that spirituality “stuff.”
