Microarray analysis was used to identify genes showing alcohol-induced differential expression between inbred strains C57BL/6J and DBA/2J. These genes were then correlated to alcohol-related QTLs to identify potential candidate genes. The experiment involved identifying genes expressed differentially in alcohol-induced and non-induced animals but the following list of candidate genes are only for alcohol-induced states.
On mouse Chromosome 2, several candidate genes were identified for Actre2 at 48 cM,Actre3 at 63 cM, Actre4 at 65 cM, and Alcp1 at 37 cM. Candidate genes for Actre2 are Dlx1 (44 cM), Frzb (49.75 cM), D2Ertd391e, and Kai1 (49.6 cM). Candidate genes for Actre3 and Actre4 are Bdnf (62 cM) and Actc1 (64 cM), respectively. Candidate genes forAlcp1 are Pbx3 (22 cM), Hspa5 (22.5 cM), Rprm, Pkp4, and March7 (formerly Axot).
