They analyzed more than 1, 400 singlenucleotidepolymorphisms, or SNPs for short, to see if any particular SNPs were more frequently carried by schizophrenia patients than unaffected people.
Two singlenucleotidepolymorphisms (SNPs), both located onthe chromosomal region 2p35, had the highest degree of associationwith alcohol dependence in a relatively homogenous patient population.
