Hi Ann,

I think so.  Many publications estimate the number of moue genes to be 
around 25,000-30,000, which is about the number we show in the Genome 
Browser (in the UCSC Genes and RefSeq Genes tracks, at least).

I took a brief look at the STS Markers track alongside the UCSC Genes 
track, and the STS Markers generally looked much smaller than the genes. 
  Each DMit locus covering an entire gene seems like a dubious result.
