1 · What the graph read from 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.

2 · The registry

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

Episodic ataxia type 2 (EA2) is an autosomal dominant inherited neurological disorder that is characterized by paroxysmal episodes of ataxia. The causative gene for EA2 is CACNA1A which codes for the alpha 1A subunit of the voltage-gated P/Q-type calcium channel (Cav2.1). We detected a novel point mutation in the CACNA1A gene in a large Austrian family. All ten affected family members harbored a heterozygous c.3089+2T>C nucleotide exchange in intron 19. In silico modeling demonstrated a loss of the splice site of exon 19 by the mutation, which most likely results in exon skipping without frameshifting or use of an alternative splice site.Clinically, the family exhibited frequent ataxic episodes accompanied by headache in some individuals, which showed a good treatment response to acetazolamide or aminopyridine. Interictal phenotype variability was high ranging from an unremarkable clinical examination to a progressive cerebellar syndrome. Detailed cognitive testing with standardized neuropsychological tests revealed specific deficits in various domains including memory,executive functions and visual abilities. Moreover, a striking coincidence of socio-phobic behavior and anxiety disorders was detected within this family, which interfered with activities of daily living and has to be taken in consideration in EA2 patient management. We here characterize the phenotype of this novel CACNA1A mutation,review the respective literature and discuss implications on diagnosis and patient management.
