Clinical characteristics and induced pluripotent stem cells (iPSCs) disease model of Fabry disease caused by a novel GLA mutation.
Article in QJM : monthly journal of the Association of Physicians, 2024. 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
backgroundFabry disease (FD) is a rare X-linked inherited disease caused by mutations in the galactosidase alpha (GLA) gene. We established a cohort of FD patients and performed whole-exome sequencing to identify some novel mutations.
aimThe aim of this study is to investigate the etiology of the novel mutation (c.72G > A, p. Trp24*)in the GLA gene in affected patients by using induced pluripotent stem cells (iPSCs) as a valuable tool.
methodsWe explored the clinical implications of this proband and examined the deleteriousness and conservation of the mutation site through bioinformatics analysis. Simultaneously, we collected the peripheral blood mononuclear cells of the affected patient, then reprogrammed them into iPSCs and assessed their enzymatic activity to confirm the function of lysosomal enzyme α-galactosidase A (α-Gal A).
resultsClinical examination of the patient demonstrated a classical FD, such as neuropathic pain, gastrointestinal disorders, deficiency of α-Gal A activity and accumulation of Lyso-Gb-3. The novel mutation located on the N-terminal region, leading to a truncation of the protein and remaining only 24 amino acids. The α-Gal A activity of the patient-specific iPSC (iPS-FD) was significantly lower (60%) than that of normal iPSCs derived from healthy donors (iPS-B1).
conclusionThis work not only elucidated the etiology of novel mutations in affected patients but also highlighted the utility of iPSCs as a valuable tool for clarifying the molecular mechanisms and providing new insights into the therapy of FD.
