[i] The random STS set was derived from The Whitehead physical map (Hudson et al. 1995) and consisted of 3519 markers that had been developed from random DNA fragments. Microsatellite STSs were the 5264 markers from the Généthon genetic map (Dib et al. 1996). Transcript-based STSs were a nonredundant set of 16,294 markers from the international RH consortium transcript map (Schuler et al. 1996). The genomic sequence set is the same one described in Table 1. The mRNA set consisted of all human, nonmitochondrial mRNA sequences from the GenBank PRI (primate) division. The two human EST sets were taken from the EST division, making use of information present in dbEST for the end of the clone insert that was read.
