No association of alcohol dependence with SLC6A5 and SLC6A9 glycine transporter polymorphisms
Addiction Biology Early View 24 July 2009

To determine whether glycine transporter polymorphisms are associated with alcoholism, three genetic variants of SLC6A5 and two polymorphisms of SLC6A9 were genotyped in 463 German non-alcoholic controls and 644 German alcohol-dependent subjects.

There was a significant association between the SLC6A5 polymorphism (rs1443547) and alcohol dependence as alcoholic individuals had a lower rate of AG-allele (χ2 = 6.048, P = 0.049, d.f. = 2), which did not remain significant after correction for multiple testing.

There was no association between SLC6A9 glycine transporter polymorphisms and alcohol dependence, and also none in haplotype analysis.
