Genotype-Phenotype Correlations and Sex Differences in ZC4H2-Associated Rare Disorder.
Article in Pediatric neurology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundZC4H2-associated rare disorder (ZARD) is caused by pathogenic variations in the ZC4H2 gene on the X chromosome. This gene codes for a zinc finger protein involved in neural development. ZARD is characterized by highly variable symptoms, potentially influenced by the sex of the individual.
methodsThe ZC4H2-Associated Rare Disorder Natural History Study is a prospective natural history study conducted among individuals with ZARD that consists of standardized interviews, developmental assessments, and neurological examinations conducted every six months for two years. In this article, we present data from baseline visits with 40 participants, the largest ZARD cohort studied thus far, focusing on genotype-phenotype correlations and sex differences. Fisher exact, maximum likelihood χ
resultsMales tended to have maternally inherited ZC4H2 pathogenic variations, whereas females tended to have de novo variations (P < 0.001). Female participants were more likely to have contractures at birth (P < 0.01), arthrogryposis multiplex congenita (P < 0.001), spasticity on examination (P < 0.1), and lower limb muscle atrophy (P < 0.05). Male participants were more likely to have seizures (P < 0.1), intermittent pain (P < 0.01), severe vision impairment (P < 0.05), dysphagia for solids (P < 0.01), and generalized muscle atrophy (P < 0.05).
conclusionsOur study suggests there is significant overlap in severity and range of symptoms between males and females, although several symptoms are more common in one sex than the other. Further analysis is needed to better understand how pathogenic variation type affects phenotype.
