A K-BROWSER screenshot of the cystic fibrosis gene region (CFTR). (Top panel) Human annotations (April 2003); (middle panel) mouse annotations (February 2003); and (bottom panel) rat annotations (June 2003). The gray bars indicate gaps (arising from insertions or deletions) in the sequences. The alignment for this region can be downloaded in PHYLIP or multiFasta format, and it is possible to navigate using zoom buttons, gene name searching, and position jumping (buttons not shown).
