High-resolution array comparative genomic hybridization analysis reveals unanticipated complexity of genetic deficiencies on chromosome V in Caenorhabditis elegans.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Genomic rearrangements are widely used in Caenorhabditis elegans research but many remain incompletely characterized at the physical level. We have used oligo-array comparative genomic analysis to assess the physical structure of 20 deficiencies and a single duplication of chromosome V. We find that while deletions internal to the chromosome appear simple in structure, terminal deletions are complex, containing duplications in addition to the deletion. Additionally, we confirm that transposon-induced deficiencies contain breakpoints that initiate at Tc1 elements. Finally, 13 of these deficiencies are known to suppress recombination far beyond the extent of the deletion. These deficiencies fall into two classes: strong and weak suppressors of adjacent recombination. Analysis of the deleted regions in these deficiencies reveals no common physical sites to explain the observed differences in recombination suppression. However, we find a strong correlation between the size of the rearranged chromosome and the severity of recombination suppression. Rearranged chromosomes that have a minor effect on recombination fall within 2% of normal chromosome size. Our observations highlight the use of array-based approaches for the analysis of rearranged genomes, revealing previously unidentified deficiency characteristics and addressing biologically relevant questions.
