L5Jcs13 maps to a gene desert. Shown are adaptations of UCSC browser displayed with selected tracks (July 2007 NCBI37/mm9 assembly). On top is the entire critical region to which L5Jcs13 maps (289 kb) with all annotated mouse and non-mouse ESTs. A graph of mammalian conservation (30-way Multiz alignment and conservation track) is indicated. The bottom half of the figure is a view of a larger region of Chr 5 in which the L5Jcs13 critical region is embedded. RefSeq genes are shown.
