<h2 id="-ncbi-variation-tools-"><span> NCBI Variation Tools </span></h2>
<p><span> This is a list of available NCBI Variation Tools for investigating and understanding human variation. </span></p>
<h3 id="-variation-services-"><span> <a href=""></a> Variation Services </span></h3>
<p><a href="/variation/services">Variation Services</a> is an API for processing medium volume of data (&lt;100K variants). It has functions for searching, normalizing, remapping, and annotating user's variants with dbSNP data.
Users that need a high volume of data (&gt;100K variants) can access the dbSNP by <a href="https://ftp.ncbi.nih.gov/snp/redesign/latest_release/">FTP</a>.</p>
<h3 id="-variation-viewer-"><span> <a href=""></a> Variation Viewer </span></h3>
<p><a href="/variation/view">Variation Viewer</a> is a tool for interactive examination and download of nucleotide variants for a specific locus. It supports both the <span data-scaytid="171" word="GRCh38"> GRCh38 </span> and GRCh37.p13 assemblies. Variation Viewer integrates data from all of the <span data-scaytid="172" word="NCBI"> NCBI </span> Variation databases and presents them in a coupled graphical and tabular report. The resulting list of variants can be saved locally using the download function. You can also upload their own variant data to this browser. More information can be found on the <a href="ftp://ftp/pub/factsheets/Factsheet_Variation_Viewer.pdf"><span data-scaytid="173" word="NCBI"> NCBI </span> Variation Viewer Fact sheet</a> and in an <a href="https://www.youtube.com/watch?v=rnWZ9MFBwUM">introductory video tutorial</a>.</p>
<h3 id="-ncbi-genome-remapping-service-"><span> <a href=""></a> NCBI Genome Remapping Service </span></h3>
<p>The <a href="/genome/tools/remap#tab=rsg"><span data-scaytid="189" word="NCBI"> NCBI </span> <span data-scaytid="191" word="Remap"> Genome Remapping </span> Service</a> is a tool that projects users' annotation data from one coordinate system to another. With the Assembly-Assembly remap, you can remap your variant calls between different assembly versions, while the Clinical Remap permits you to remap data between RefSeqGenes or LRGs and an assembly, using NCBI calculated alignments. More information can be found on the <a href="ftp://ftp/pub/factsheets/Factsheet_Remap.pdf"><span data-scaytid="194" word="NCBI"> NCBI </span> <span data-scaytid="195" word="Remap"> Remap </span> Service fact sheet</a>. The remapping service has a web interface as well as an <a href="/genome/tools/remap/docs/api">API</a> for bulk processing.</p>
<h3 id="-phegeni-"><span> <a href=""></a> PheGenI </span></h3>
<p>The Phenotype-Genotype Integrator (<a href="/gap/phegeni"><span data-scaytid="143" word="PheGenI">PheGenI</span></a>) is a tool that integrates the search and retrieval of associated genotype-phenotype data from National Human Genome Research Institute (NHGRI) Genome-wide Association Study (GWAS) Catalog integrated with data housed in Gene, dbGaP, OMIM, GTEx and dbSNP. It provides search by genotype and phenotype. The dbSNP Data in NCBI PheGenI is only mapped GRCh38 at this time. More information can be found on the <a href="ftp://ftp/pub/factsheets/Factsheet_PheGenI.pdf"><span data-scaytid="194" word="NCBI"> NCBI </span> Phenotype-Genotype Integrator fact sheet.</a></p>
