Heterozygous PNPT1 Variants Cause a Sensory Ataxic Neuropathy.
Article in European journal of neurology, 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
backgroundBiallelic variants in polyribonucleotide-nucleotidyltransferase-1 (PNPT1) have been associated with a range of phenotypes from syndromic hearing loss to Leigh's syndrome. More recently, heterozygous variants in PNPT1, have been reported in three families with cerebellar ataxia and prominent sensory neuropathy.
methodsWhole genome sequencing was performed in two families with autosomal dominant sensory ataxic neuropathy (SAN).
resultsSegregating heterozygous splice site (c.2014-3C>G) and nonsense (p.Arg715Ter) variants were detected in both families. All patients initially presented with an isolated SAN clinically and neurophysiologically with subsequent variable cerebellar involvement.
conclusionWe report two heterozygous PNPT1 variants in two families with a predominant SAN, including the novel p.Arg715Ter. This strengthens the argument of PNPT1 causing dominant disease and highlights a new cause for dominantly inherited SAN.
