 <p>The NCBI <strong>AL</strong>lele <strong>F</strong>requency <strong>A</strong>ggregator (<a href="https://www.ncbi.nlm.nih.gov/snp/docs/gsr/alfa/">ALFA</a>)
  pipeline is developed to compute allele frequency for variants in dbGaP
  across approved un-restricted studies and to provide the data as 
 open-access to the public through dbSNP. The goal of the ALFA project is
  to make frequency data from over 1M dbGaP subjects open-access in 
 future releases to facilitate discoveries and interpretations of common 
 and rare variants with biological impacts or causing diseases.</p>
 <p>The R4 release of 408,709 subjects included allele 
 counts and frequency for 15.5 million rs site including 959,966 ClinVar RS IDs. More information about ALFA can 
 be found at https://www.ncbi.nlm.nih.gov/snp/docs/gsr/alfa/ and any 
 questions about ALFA track data should be forwarded to 
 &lt;mailto:snp-admin@ncbi.nlm.nih.gov&gt;.</p>

 <h2>Display Conventions and Configuration</h2>
 <h3>Labels</h3>
 <p>The variant label is the dbSNP reference SNP ID (rsid).</p>
 <h3>Mouseover</h3>
 <p>The mouseover (displayed when the mouse is hovered over a variant) shows the following:</p>
 <ul>
 <li>Chromosome</li>
 <li>position</li>
 <li>Reference allele and frequency</li>
 <li>Alternate allele and frequency</li>
 </ul>
 <h3>&nbsp;</h3>
 <h3>Detail Page</h3>
 <p>The detail page contains the following:</p>
 <ul>
 <li><a>link to the dbSNP RS Page of the variation</a></li>
 <li><a>chromosome position</a></li>
 <li><a>mouseover label (allele frequencies)</a></li>
 <li><a>track hub date last updated</a></li>
 </ul>
 <p>&nbsp;&nbsp;</p>
 <h3>Variant Colors</h3>
 <p><a>The colors indicate the alternate allele frequencies</a><a>. </a></p>
 <ul>
 <li style="color: #ff0000;"><strong>red: alternate allele frequency falls in [0.5, 1]<br></strong></li>
 </ul>
 <ul>
 <li style="color: #0000ff;"><strong>blue: alternate allele frequency falls in [0.4, 0.5)<br></strong></li>
 </ul>
 <ul>
 <li style="color: #ee82ee;"><strong>violet: alternate allele frequency falls in [0.3, 0.4)<br></strong></li>
 </ul>
 <ul>
 <li style="color: #9c6597;"><strong>light violet: alternate allele frequency falls in [0.2, 0.3)<br></strong></li>
 </ul>
 <ul>
 <li style="color: #007fff;"><strong>light azure: alternate allele frequency falls in [0.1, 0.2)<br></strong></li>
 </ul>
 <ul>
 <li style="color: #a52a2a;"><strong>brown: alternate alelle frequency falls in [0, 0.1)<br></strong></li>
