These studies revealed some interesting new candidate genes for alcohol dependence including cadherin 11 (CDH11) [22] and cadherin 13 (CDH13) [22, 25], GATA binding protein 4 (GATA4) [25], solute carrier family 22, member 18 (SLC22A18) [19], and potassium large conductance calcium-activated channel, subfamily M, alpha member 1 gene (KCNMA1) [23]. Here, SLC67A1 is linked to alcohol dependence.
