Unusual presentations and intrafamilial phenotypic variability in infantile onset Alexander disease.

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
Alexander disease is an hereditary leukodystrophy related to mutations of GFAP. Classically AxD was divided in infantile, juvenile, and adult subgroups. Recent data suggested considering only two subtypes: type I (infantile onset with lesions extending to the cerebral hemispheres); type II (adult onset with primary involvement of subtentorial structures). We report two related and one unrelated patients presenting with a peculiar association of clinical and neuroradiological features. GFAP analysis disclosed the presence of one novel and two previously reported mutations. Our patients underline the importance of considering AxD in patients with bulbar symptoms and autonomic dysfunction even if MRI shows only posterior fossa abnormalities, supporting the hypothesis of a third type of AxD sharing features of both type I and type II. The evidence of an intrafamilial phenotypic variability suggests the possible role of still unknown factors influencing the effect of GFAP mutation and determining the phenotype.
