The human genome teems with SNPs, single-letter changes in DNA that can increase susceptibility to diseases such as cancer and Alzheimer's. For help viewing and tracking these variations, check out the new Genewindow from the U.S. National Cancer Institute. Genewindow is a DNA browser that lets you scroll through a particular gene nucleotide by nucleotide, identifying SNPs and other landmarks, such as protein-coding segments. You can also see how each SNP changes the sequence of the gene's protein. The tool requires the free Adobe SVG viewer and can be balky with some browsers.
