Database Description

PolyDoms is an integrated database of human coding SNPs and related data. Unlike other databases of similar nature, apart from integrating several cSNP and protein-related information resources, we predict the implications of the non-synonymous SNPs using two well known algorithms (SIFT and PolyPhen). All these results are presented in an intuitive visualization that depicts the cSNPs mapped onto protein domains and highlights those nsSNPs that are potentially damaging/deleterious or have been reported as disease allelic variants (based on OMIM). The query interface also supports searching for a list of proteins associated with any gene ontology term, pathway, disease term, or gene family. Results can also be downloaded as a spreadsheet. The visualization page also provides links to several other related sources and dynamic links to literature references. We strongly believe that the nsSNPs that are predicted to be functional upon evolutionary conservation analysis and are located in functional protein domains and/or motifs constitute an excellent resource for specific molecular studies to elucidate the direct consequences of these variations on protein function and interaction, which could also eventually help the molecular epidemiology and genetic studies aiming to reveal the genetic variationdisease risk association.
