Targeting Lysine α-Ketoglutarate Reductase to Treat Pyridoxine-Dependent Epilepsy.
Article in The Journal of neuroscience : the official journal of the Society for Neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Pyridoxine-dependent epilepsy (PDE), a rare autosomal recessively inherited metabolic disease, results from mutations in ALDH7A1, a gene crucial for lysine metabolism. Although early high-dose pyridoxine treatment can control seizures, ∼75% of PDE patients still have intellectual disabilities. In this study, we test the hypothesis of substrate reduction therapy for PDE by genetically perturbing lysine α-ketoglutarate reductase (LKR), an enzyme upstream of the defective ALDH7A1, in male and female laboratory mice. A homozygous mutation in LKR completely abolishes the accumulation of toxic lysine catabolism intermediates (α-aminoadipic-δ-semialdehyde and its cyclic form, δ-1-piperideine-6-carboxylate), ends the epileptic state, and restores the defective brain development and cognitive impairments in ALDH7A1-deficient mice. Therefore, these genetic data prove the concept of the effectiveness of substrate reduction therapy for PDE via LKR inhibition.
