Variant profiles of genes mapping to chromosome 16q loss in Wilms tumors reveals link to cilia-related genes and pathways.

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
backgroundWilms tumor is the most common pediatric renal tumor and the fourth most common malignancy in children. Chromosome 16q deletion(del) or loss of heterozygosity (LOH) has been correlated with recurrence and overall poor prognosis, such that patients with 16qLOH and 1p allelic loss are treated with more aggressive chemotherapeutic regimens.
methodsIn the present study, we have compared the variant profiles of Wilms tumors with and without 16q del/LOH using both data available from the TARGET database (42 samples) and tumors procured from our legacy collection (8 samples). Exome-Seq data was analyzed for tumor specific variants mapping to 16q. Whole exome analysis was also performed. An unbiased approach for somatic variant analysis was used to detect tumor-specific, somatic variants.
resultsOf the 72 genes mapping to 16q, 42% were cilia-related genes and 28% of these were found to carry somatic variants specific to those tumors with 16qdel/LOH. Whole exome analyses further revealed that 30% of cilia-related genes across the genome carried alterations in tumors both with and without 16qdel/LOH. Additional pathway analyses revealed that many cilia-related pathway members also carried deleterious variant in these tumors including Sonic Hedgehog (SHh), Wnt, and Notch signaling pathways.
conclusionsThe data suggest that cilia-related genes and pathways are compromised in Wilms tumors. The genes on chromosome 16q that carry deleterious variants in cilia-related genes may account for the more aggressive nature of tumors with 16q del/LOH.
