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

PIEZO2 is the principal mechanosensory channel for proprioception, touch, and many interoceptive processes, yet key details of how PIEZO channels convert force into electrochemical signals remain unclear. Here, we report fraternal twins with proprioceptive ataxia and scoliosis who carry an unreported PIEZO2 missense variant (N2434K) in compound heterozygosity with a null variant. Gene-edited mice confirm that N2434K is disease-causing, with in vivo recordings demonstrating deficits in sensory neuron mechanical responses. Despite normal membrane expression, the variant has severely reduced mechanically evoked current, which is suggestive of defective gating. N2434 is conserved between PIEZO1 and PIEZO2 and resides in the cap-pore linker, which bridges the extracellular cap and ion-conducting pore. Computational modeling, site-directed mutagenesis, and single-molecule imaging reveal that this region is essential for channel-wide conformational changes during gating. By explaining how a single amino acid change produces a hypomorphic PIEZO2 allele, our findings broaden the clinical spectrum of PIEZO2 disorders and offer structural insight into mechanotransduction.
