 <H2>Description</H2>
 
 <P>
 This composite track contains information about single nucleotide polymorphisms (SNPs)
 and small insertions and deletions (indels) &mdash; collectively Simple
 Nucleotide Polymorphisms &mdash; from
 <A HREF="https://www.ncbi.nlm.nih.gov/SNP/" target=_blank>dbSNP</A>, available from
 <A HREF="ftp://ftp.ncbi.nih.gov/snp/organisms" target=_blank>ftp.ncbi.nih.gov/snp</A>.
 You can click into each track for a version/subset-specific description.</P>
 <P>
 This collection includes numbered versions of the entire dbSNP datasets
 (All SNP) as well as three tracks with subsets of the items in that version. 
 Here is information on each of the subsets:
 <UL>
+<LI><B>dbSNP 153:</B> The dbSNP build 153 is composed of 5 subtracks. Click the track for
+    a description of the subtracks.</LI>
 <LI><B>Common SNPs:</B> SNPs that have a minor allele frequency
     of at least 1% and are mapped to a single location in the reference
     genome assembly.  Frequency data are not available for all SNPs,
     so this subset is incomplete.</LI>
 <LI><B>Flagged SNPs:</B> SNPs flagged as clinically associated by dbSNP, 
     mapped to a single location in the reference genome assembly, and 
     <em>not</em> known to have a minor allele frequency of at least 1%.
     Frequency data are not available for all SNPs, so this subset may
     include some SNPs whose true minor allele frequency is 1% or greater.</LI>
 <LI><B>Mult. SNPs:</B> SNPs that have been mapped to multiple locations
     in the reference genome assembly.</LI>
