When looking for SNPs in GN2, the gene annotations (and, I think, the SNPs) of the results do not match the query. Searching for a gene gives correct coordinates in the search box at http://www.genenetwork.org/snp_browser, but the results are for the same coordinates in mm9 (see screenshot).
The example is for a search for 'Snx6' (chr12 54.746356 - 54.795662).
