A Rare Recurrent 4q25 Proximal Deletion Not Involving the PITX2 Gene: A Genomic Disorder Distinct from Axenfeld-Rieger Syndrome.

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
Haploinsufficient microdeletions within chromosome 4q25 are often associated with Axenfeld-Rieger syndrome. A de novo 4q25 deletion, 675 kb proximal to PITX2, has previously been reported once in an adult patient. The patient did not have Axenfeld-Rieger anomaly, but instead had intellectual disability and a complex behavioral phenotype with withdrawn, stereotypic, and ritualistic behavior. Array comparative genome hybridization demonstrated a smaller, overlapping 4q25 deletion in a 2-year-old patient and his mother, both having significant phenotypic overlap with the initially reported patient. All 3 patients have distinct facial features (including mild hypotelorism and subtle mandibular asymmetry), developmental delay, and complex behavioral difficulties. A genotype-phenotype correlation narrows the shared phenotype to a common COL25A1 gene aberration and proposes that the concurrent EGF gene loss has a significant impact on the phenotypic severity. Overall, our patients provide data to support the existence of a novel 4q25 proximal deletion syndrome.
