Congenital Mirror Movements in A Family with TUBB2B Mutation.
Article in Movement disorders clinical practice, 2026. 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
backgroundCongenital mirror movements (CMM) are involuntary movements on one side of the body that mirror intentional movements on the opposite side, which persist in adult life. While mutations in DCC, RAD51, NTN1 and other genes have been associated with CMM, recent evidence suggests tubulinopathies, including TUBB3 mutations, may also contribute. CASES: An 11-year-old girl with developmental delay and CMM was evaluated, along with her mother and sibling via clinical assessments, neuroimaging, and genetic analysis. Diffusion tensor imaging (DTI) was used to assess corticospinal tract abnormalities. A heterozygous TUBB2B variant was identified in all three affected individuals. DTI revealed reduced corticospinal tract decussation, similar to findings in other genetic causes of CMM.
conclusionsThis study highlights new phenomenology of congenital mirror movements associated with TUBB2B-related tubulinopathy, highlighting the role of TUBB2B mutations in neuronal migration, expanding the genetic spectrum of congenital mirror movements.
