1 · What the graph read from it

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.

2 · The registry

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

backgroundMarfan syndrome (MFS) is a genetic disorder affecting connective tissue, with variable incidence rates. A significant portion of cases stems from novel genetic variants, while others inherit it from affected parents.

objectiveThis study focuses on identifying the genetic cause of MFS in a specific family, using whole-exome sequencing (WES).

methodsA 15-year-old male with confirmed MFS was examined, showing symptoms of palpitations and severe mitral valve regurgitation. WES was performed, followed by confirmation with Sanger sequencing. Variants were assessed for pathogenicity using bioinformatics tools and the American College of Medical Genetics and Genomics (ACMG) guidelines.

resultsOne potentially novel pathogenic variant was found in exon 14 of the FBN1 gene: c.1676delCinsAAT, p.Ala559GlufsTer21. In silico analysis suggested a deleterious impact on protein structure and function, supporting their pathogenic classification.

conclusionThe identification of this novel variant highlights the importance of the FBN1 gene in MFS, especially its cardiovascular manifestations. Early intervention can improve patient outcomes, while ongoing research holds promise for further advancements in treatment for Marfan syndrome.
