Currently includes information from dbGaP, the NHGRI GWAS Catalog, and GTeX. Displays results on the genome, on sequence, or in tables for download. Primer-BLAST The Primer-BLAST tool uses Primer3 to design PCR primers to a sequence template. The potential products are then automatically analyzed with a BLAST search against user specified databases, to check the specificity to the target intended. ProSplign A utility for computing alignment of proteins to genomic nucleotide sequence. It is based on a variation of the Needleman Wunsch global alignment algorithm and specifically accounts for introns and splice signals. Due to this algorithm, ProSplign is accurate in determining splice sites and tolerant to sequencing errors. PubChem Power User Gateway (PUG) PUG provides access to PubChem services via a programmatic interface. PUG allows users to download data, initiate chemical structure searches, standardize chemical structures and interact with the E-utilities. PUG can be accessed using either standard URLs or via SOAP. PubChem Standardization Service Standardization, in PubChem terminology, is the processing of chemical structures in the same way used to create PubChem Compound records from contributors' original structures. This service lets users see how PubChem would handle any structure they would lite to submit.

Due to this algorithm, Splign is accurate in determining splice sites and tolerant to sequencing errors. TaxPlot A tool for comparing genomes on the basis of the protein sequences they encode. To use TaxPlot, one selects a reference genome and two species for comparison. Pre-computed BLAST results are then used to plot a point for each predicted protein in the reference genome, based on the best alignment with proteins in each of the two genomes being compared. Taxonomy Browser Supports searching the taxonomy tree using partial taxonomic names, common names, wild cards and phonetically similar names. For each taxonomic node, the tool provides links to all data in Entrez for that node, displays the lineage, and provides links to external sites related to the node. Taxonomy Common Tree Generates a taxonomic tree for a selected group of organisms. Users can upload a tile of taxonomy IDs or names, or they can enter names or IDs directly. Taxonomy Statistics Displays the number of taxonomic nodes in the database for a given rank and date of inclusion. Taxonomy Status Reports Displays the current status of a set of taxonomic nodes or IDs. Variation Reporter A tool designed to search for and report human sequence variation data from dbSNP and dbVar. Individual variations or batch lies can be submitted in HGVS, GVF or BED formats. Related information will be retrieved and reported in a downloadable table containing variation identifiers, nucleotide and cytogenetic band locations on various genomic assemblies, allele type and minor allele frequencies, predicted functional consequences (missense, nonsense, fra mesh iff, splice site, etc.), reported clinical significance, and relevant citations.
