Genetic Background of Eosinophilic Esophagitis and Esophageal Atresia in Children.
Article in Digestive diseases and sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsThe pathophysiology of eosinophilic esophagitis (EoE) is associated with a strong heritability and esophageal-specific genetic variants. Patients with esophageal atresia (EA) may be at higher risk of developing EoE considering the recently discovered genetic similarities between these disorders. This study aimed to identify genetic mutations associated with EoE, explore their potential role in susceptibility to concurrent EA, and evaluate the relationship between these mutations, clinical course, and treatment response.
methodsWhole-exome sequencing was performed to identify the potential genomic regions associated with an increased risk of these disorders, and the analysis was expanded for candidate genes.
resultsA total of 35 cases (EA + EoE +; n = 7) were included. Pathogenic mutations in genes associated with EoE were identified in 2 cases, while likely pathogenic variants were identified in 5 cases. No polymorphisms were detected in 5 cases. Variants of uncertain significance (VUS) were identified in genes associated with EoE in 18 cases and in candidate genes in 7 cases. Patients with VUS exhibited a high percentage of associated EA, increased rates of atopy, and a notable response to treatment. The duration of the clinical response was significantly longer in individuals without genetic mutations (p-value:0.006). Among the isolated EoE cases, 50% had variants in genes previously associated with EoE, whereas in EA + EoE + cases, this rate increased to 71%, suggesting a stronger genetic predisposition in EA + EoE + cases.
conclusionOur study highlights the role of genetic mutations in the etiology of EoE. The identification of novel gene variants and new insights into etiopathogenesis are anticipated to enhance diagnosis, screening, and treatment strategies.
