CNTN6 Modulates Slit-Robo Signaling in Cortical GABAergic Interneuron Migration.
Article in Neuroscience bulletin, 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
Contactin-6 (CNTN6) is a membrane protein that belongs to the contactin subgroup of the immunoglobulin (Ig) superfamily. Substantial evidence supports a significant role of its encoding gene, CNTN6, in neurodevelopment and psychiatric disorders, including autism spectrum disorders and schizophrenia. Further studies are required to clarify the role of CNTN6 in the etiology of these disorders. Here, we show that the first three Ig domains of the extracellular region of CNTN6 compete with Robo2 for binding to the leucine-rich repeat (LRR) domain of Slit2 and inhibit Slit-Robo signaling, thereby regulating neurite outgrowth in cortical neurons. The repulsive effect of Slit2 on the migration of GABAergic neurons was attenuated by the interaction between CNTN6 and Slit2, both in vitro and ex vivo. Male mice deficient in Cntn6 exhibited a significant reduction in the number of calbindin-positive GABAergic neurons in the motor cortex. Cntn6-null male mice also exhibited impaired social recognition and disrupted self-grooming behavior. These findings suggest that CNTN6 inhibits Slit-Robo signaling and modulates the migration of a subset of GABAergic neurons, thereby contributing to the development of autism-related behaviors associated with CNTN6 dysfunction.
