A CRISPR activation screen reveals a cilia disassembly pathway mutated in focal cortical dysplasia.
Article in Science advances, 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
Defective assembly of primary cilia causes ciliopathies, but cilia disassembly and its role in disease remain poorly understood. From a genome-wide CRISPR activation (CRISPRa) screen for negative regulators of ciliary function, we find here that the F2R G protein-coupled receptor, sterile alpha and TIR motif-containing 1 (SARM1) hydrolase, ryanodine receptors, peri-centrosomal calcium signaling, and RhoA form a functional pathway that is necessary and sufficient for cilia disassembly. Highlighting the significance of this pathway, several components are somatically mutated in focal cortical dysplasia (FCD), a neurological disorder characterized by intractable epilepsy. Supporting the functional impact of these variants, patient-derived SARM1 and RhoA mutations potentiate cilia loss, and a RhoA variant impairs cortical development. Conversely, SARM1 inhibition restores cilia in cells with FCD-associated alterations. Together, our work identifies a pathway for cilia disassembly, implicates aberrant pathway activation as a feature of FCD-associated mutations, and illustrates the potential of CRISPRa screening to provide insight into diseases caused by somatic mutations.
