Unraveling MECP2 structural variants in previously elusive Rett syndrome cases through IGV interpretation.
Article in NPJ genomic medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Rett syndrome (RTT) is a severe neurodevelopmental disorder, with MECP2 mutations accounting for 90-95% of classic and 50-70% of atypical cases. However, many clinically diagnosed RTT patients remain without molecular diagnoses. While point mutations and large rearrangements in MECP2 are well studied, the role of small-intermediate structural variants (SVs) remains mostly elusive. Using standard short-read whole genome sequencing, we identified novel de novo SVs in three out of three previously unresolved RTT cases: a complex SV with two deletions ( ~ 5Kbp and ~60Kbp) and a ~105Kbp inversion; a ~200Kbp translocation; and a ~3Kbp deletion. These findings suggest that such elusive SVs might be a common cause for "MECP2-negative" RTT. Incorporating SV detection into routine genetic testing through bioinformatic analysis of short-read sequencing or manual review using IGV could improve diagnostic rates and expand our understanding of RTT and similar disorders.
