Abstract

Understanding how genetic variation affects the molecular function of gene products is an emergent area of bioinformatic research. Here, we present updates to MutDB (http://www.mutdb.org), a tool aiming to aid bioinformatic studies by integrating publicly available databases of human genetic variation with molecular features and clinical phenotype data. MutDB, first developed in 2002, integrates annotated SNPs in dbSNP and amino acid substitutions in Swiss-Prot with protein structural information, links to scores that predict functional disruption and other useful annotations. Though these functional annotations are mainly focused on nonsynonymous SNPs, some information on other SNP types included in dbSNP is also provided. Additionally, we have developed a new functionality that facilitates KEGG pathway visualization of genes containing SNPs and a SNP query tool for visualizing and exporting sets of SNPs that share selected features based on certain filters.

SNP query tool snapshot highlighting SNP filtering. Multiple filtering options include: validation (T/F), HapMap (31) (T/F), Location, avHet, avHetSE, HapMap Frequency (CEU, CHB, JPT, YRI), SIFT score and UCSC conservation. Users can preview current filtering criteria by scrolling over pop-up window link. Once SNPs are selected, Haploview like images can be rendered showing HapMap LD structure (lower right).
