-Many rare developmental disorders are caused by variants in genes that write, read or erase
+Many rare developmental disorders are caused by variants in genes that write, read, or erase
 DNA methylation, and such a variant leaves a reproducible pattern of altered methylation across
 the genome of the affected person. A pattern of this kind is called an episignature, and because
 it can be measured in a blood sample it is used in diagnostics to decide whether a variant of
 uncertain significance is really the cause of a patient's condition.
 </p>
 
 <p>
 This collection holds the CpG positions that published episignatures are built from. It
 currently contains two tracks:
 </p>
 
 <table class="stdTbl">
   <tr><th>Track</th><th>Description</th></tr>
   <tr><td><a href="hgTrackUi?g=methaDory">MethaDory</a></td>
       <td>CpG probes of the published episignatures compiled for the MethaDory classifier,
           covering more than 100 disorders from 74 studies</td></tr>
   <tr><td><a href="hgTrackUi?g=epigenCentral">EpigenCentral</a></td>
       <td>CpG probes of the 24 episignatures curated by the EpigenCentral portal,
           covering 23 disorders</td></tr>
 </table>
 
 <p>
 The two sets were compiled independently and overlap heavily but neither contains the other,
-so a CpG site can appear in one, the other or both.
