Regional assignment of EST sequences on human chromosome 13. 1996

We have used a panel of somatic cell hybrids carrying structural rearrangements of human chromosome 13 to regionally localise 10 expressed sequence tags (ESTs) from this chromosome. Three of these genes were not present in the somatic cell hybrid PGME, which contains chromosome 13 as its major human component. Using a panel of somatic cell hybrids, two of these genes were localised to chromosome 8 and one to chromosome 16. Using the PCR primers as published, it was impossible to map one EST; consequently, a YAC containing this gene was isolated, and fluorescence in situ hybridisation was used to map the gene to 13q14. The distribution of the remaining six chromosome 13-specific ESTs was nonrandom; one mapped to 13q14 and the remaining five to 13q12, with three mapping within the proximal portion and two mapping within the distal portion of this region.

D016133 Polymerase Chain Reaction In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D016324 Sequence Tagged Sites Short tracts of DNA sequence that are used as landmarks in GENOME mapping. In most instances, 200 to 500 base pairs of sequence define a Sequence Tagged Site (STS) that is operationally unique in the human genome (i.e., can be specifically detected by the polymerase chain reaction in the presence of all other genomic sequences). The overwhelming advantage of STSs over mapping landmarks defined in other ways is that the means of testing for the presence of a particular STS can be completely described as information in a database.
