a sodium/bile acid cotransporter, also replicated; expression of SLC10A2 is regulated in part by retinol (Neimark et al., 2004). Three other SNPs replicated when the subgroup with early-onset alcoholism was analyzed: rs35164 just downstream of CDH11 (a type II classical cadherin), rs1927384, which lies between FGF14 (fibroblast growth factor 14) and TPP2 (tripeptidyl peptidase II), and rs6729553 in DNAH6 (axonemal dynein heavy chain 6, a microtubule-associated motor protein important in retrograde axonal organelles (Schnapp and Reese, 1989)).
