Late-Onset Krabbe Disease: Case Report of Two Patients in a Chinese Family and Literature Review.
Review in Molecular genetics & genomic medicine, 2025. 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
backgroundKrabbe disease (KD; globoid cell leucodystrophy) is a rare autosomal recessive lipid storage disorder that affects the white matter of the peripheral and central nervous. Late-onset KD is less frequently diagnosed and often presents with milder symptoms, making accurate diagnosis challenging, especially when distinguishing it from peripheral neuropathy. In this report, we present two cases of late-onset KD in a Chinese family. The first case involves a 25-year-old female who sought treatment due to long-standing spastic gait and deformities in her lower limbs. A muscle biopsy revealed muscle atrophy, and electromyography indicated neurogenic damage. Her 27-year-old sister (Case 2) exhibited similar lower limb weakness, along with more severe central and peripheral neurological symptoms.
methodsThe patients' peripheral blood was retained for galactocerebrosidase (GALC) enzyme activity assaying and whole exome gene sequencing.
resultsGALC enzyme activity assaying showed decreased GALC activity and gene sequencing revealed homozygous mutation of p.L634S (c.1901T>C) in the two cases.
conclusionThis study broadens the scope for considering of KD in the diagnosis of patients presenting with muscle weakness and deformities in the lower limbs.
