A Novel Mutation in CNTNAP1 Gene Causes Disorganization of Axonal Domains, Hypomyelination and Severe Neurological Deficits.
Article in Journal of neuroscience research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
CNTNAP1 encodes the contactin-associated protein 1 (Cntnap1) which localizes to the paranodal region in all myelinated axons and is essential for axonal domain organization and the propagation of action potentials. To date, close to 45 reported human CNTNAP1 variants have been identified that are associated with dysregulation and disorganization of the axonal domains, resulting in various forms of congenital hypomyelinating neuropathies in children. Currently, no treatments are available for neuropathies caused by CNTNAP1 variants, highlighting the importance of fully characterizing these mutations and their impact on Cntnap1 functions. To understand the importance of a novel human CNTNAP1 likely pathogenic variant that changes glycine at position 349 to valine in a child who also carries a CNTNAP1 truncation and displayed severe neurological deficits, we used CRISPR/Cas9 methodology and introduced a single nucleotide substitution in the mouse Cntnap1 gene, resulting in glycine at 350 to valine (Cntnap1
