 <h2>Data Access</h2>
 <p>
 Since dbSNP has grown to include approximately 700 million variants, the size of the All dbSNP (153)
 subtrack can cause the
 <a href="../../cgi-bin/hgTables" target=_blank>Table Browser</a> and
 <a href="../../cgi-bin/hgIntegrator" target=_blank>Data Integrator</a>
 to time out, leading to a blank page or truncated output,
-unless queries are restricted to a chromosomal region or
-to a specific set of rs# IDs (which can be pasted/uploaded into the Table Browser),
+unless queries are restricted to a chromosomal region, to particular defined regions, to a specific set 
+of rs# IDs (which can be pasted/uploaded into the Table Browser),
 or to one of the subset tracks such as Common (~15 million variants) or ClinVar (~0.5M variants).
