atSNP Search

atSNP Search is a web-based tool and database for analysis of human genome motifs with reference and variant alleles. The atSNP algorithm assesses and tests the variant alteration significance. atSNP also produces graphical representations of the motif matches. Currently, the database contains over 37 billion variant-motif pairs.
