Association Study of Alcoholism Subtypes with a Functional Promoter Polymorphism in the Serotonin Transporter Protein Gene

Abstract

Variable findings in the literature in relation to the association of 5'-HTTLPR alleles to alcohol dependence seem to be due to factors other than the composition of study samples in terms of univariate typologies based on sex, comorbid drug dependence, or age of onset of alcohol dependence.
