A novel compound heterozygous mutation in AARS2 gene (c.965 G > A, p.R322H; c.334 G > C, p.G112R) identified in a Chinese patient with leukodystrophy involved in brain and spinal cord.
Article in Journal of human genetics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Leukodystrophies are genetic disorders leading to progressive white matter degeneration in the central nervous system. Mitochondrial aminoacyl tRNA synthase protein is encoded by the nuclear gene AARS2. An autosomal recessive mutation in this gene has been linked to AARS2 mutation-related adult-onset leukodystrophy (AARS2-L) or infantile mitochondrial cardiomyopathy. To date, only 16 AARS2-L cases have been reported in English literature. Thus, the clinical and genetic characteristics of this disease remain to be defined. Through whole-exome sequencing, we identified a Chinese patient with leukodystrophy related to two novel compounds heterozygous mutation in AARS2 (c.965 G > A, p.R322H; c.334 G > C, p.G112R). These two compounds heterozygous variants in AARS2 gene co-segregated with disease in his family. And pyramidal tracts in the spinal cord were involved. Our findings have important implications on genetic counseling for any case with leukodystrophy and extend the mutational spectrum in AARS2 gene.
