Book excerpt: For this project, 22 Expressed Sequence Tags (ESTs) were fine mapped to regions of human chromosome 19. An EST is a short DNA sequence that occurs once in the genome and corresponds to a single expressed gene. 32P-radiolabeled probes were made by polymerase chain reaction for each EST and hybridized to filters containing a chromosome 19-specific cosmid library. The location of the ESTs on the chromosome was determined by the location of the ordered cosmid to which the EST hybridized. Of the 22 ESTs that were sublocalized, 6 correspond to known genes, and 16 correspond to anonymous genes. These localized ESTs may serve as potential candidates for disease genes, as well as markers for future physical mapping.
