G6PD deficiency as a underrecognized genetic risk factor for rare neurological disorders: evidence from a population-based genetic analysis.
Article in Frontiers in genetics, 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
Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is traditionally recognized as a risk factor for drug- or infection-induced hemolytic anemia. Emerging evidence implicates potential roles of G6PD in neurodevelopment, yet its association with rare neurological disorders remains underexplored in population-based genetic studies, especially within the Chinese population. Methods: We conducted a retrospective case-control study utilizing whole-exome sequencing (WES) data from a Chinese cohort. Six most prevalent pathogenic Results: After adjusting for sex, the overall carrier rate of pathogenic G6PD variants was significantly higher in patients with neurological disorders than in controls (adjusted OR = 2.44, 95% CI: 1.18-5.06, p = 0.014). Further comparisons across specific groups revealed distinct patterns: affected male patients had a higher carrier rate than their own unaffected fathers (OR = 2.30, 95% CI: 1.08-4.91, p = 0.043), and mothers of case patients showed a higher carrier rate than mothers of controls (OR = 2.03, 95% CI: 1.09-3.78, p = 0.030). The variants NM_001042351.3: c.1376G>T (G6PD Canton) and NM_001042351.3:c.1388G>A (G6PD Kaiping) were the most prevalent across all groups. Conclusion: This population-based genetic analysis provides preliminary evidence that G6PD deficiency may be a underrecognized genetic risk factor for rare neurological disorders in Chinese children. The findings suggest a potential maternal genetic contribution and indicate that the phenotypic spectrum of G6PD deficiency may extend beyond hematological manifestations to include neurodevelopmental vulnerability. Important limitations include the lack of functional validation and the use of a clinical control group. Further prospective studies incorporating G6PD enzyme activity assessment and functional investigations are warranted to elucidate the underlying mechanisms.
