Sex chromosome-wide association analysis suggested male-specific risk genes for alcohol dependence

Alcohol dependence is more common among men than among women. Potential
explanations for this include the role of genes in sex chromosomes (X and Y). In
the present study, we scanned the entire Y chromosome and its homologs on the X
chromosome in men to identify male-specific risk genes for alcohol
dependence.
