ATP-binding cassette (ABC) genes encode a family of transport proteins known to be involved in a number of human genetic diseases. In this study, we characterized the ABC superfamily in Mus musculus through in silico gene identification and mapping and phylogenetic analysis of mouse and human ABC genes. By querying dbEST with amino acid sequences from the conserved ATP-binding domains, we identified and partially sequenced 18 new mouse ABC genes, bringing the total number of mouse ABC genes to 34. Twelve of the new ABC genes were mapped in the mouse genome to the X chromosome and to 10 of the 19 autosomes. Phylogenetic relationships of mouse and human ABC genes were examined with maximum parsimony and neighbor-joining analyses that demonstrated that mouse and human ABC orthologs are more closely related than are mouse paralogs. The mouse ABC genes could be grouped into the seven previously described human ABC subfamilies. Three mouse ABC genes mapped to regions implicated in cholesterol gallstone susceptibility.
