Behavioral genomics identifies Creld1 as a cross-modal regulator of somatosensation.
Article in Nature neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Somatosensation is mediated by dorsal root ganglion (DRG) neurons, which convert physical and chemical stimuli into electrical signals. However, the full repertoire of molecular components underlying somatosensation remains incompletely identified. Here we developed an efficient postnatal CRISPR-Cas9 knockout platform for interrogating DRG-expressed genes (such as Piezo2, Trpv1 and Scn9a) in mice using AAV9-mediated single-guide RNA delivery. Combining this approach with somatosensory behavioral assays, we performed a targeted screen of 20 genes and identified Creld1 as a cross-model regulator of somatosensation. Either single-guide RNA-mediated postnatal knockout or tamoxifen-induced Cre-mediated deletion of Creld1 in DRG neurons resulted in profound behavioral deficits in touch, temperature, pain and itch, whereas its overexpression enhanced touch and thermal responses. Mechanistically, CRELD1 functions as an auxiliary regulator of voltage-gated sodium channels (Na
