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

backgroundSpinocerebellar ataxia type 28 (SCA28) is related to mutations of the ATPase family gene 3-like 2 gene (AFG3L2). To date, 13 private missense mutations have been identified in families of French, Italian, and German ancestry, but overall, the disorder seems to be rare in Europe. Here, we report a kindred of German ancestry with four affected family members presenting with slowly progressive ataxia, mild pyramidal tract signs and slow saccades.

methodsAfter excluding repeat expansions in the genes for SCA1-3, 6-8, 10, 12, and 17, Sanger sequencing of the coding regions of TTBK2 (SCA11), KCNC3 (SCA13), PRKCG (SCA14), FGF14 (SCA27) and AFG3L2 (SCA28) was performed. The 17 coding exons of AFG3L2 with flanking intronic sequences were amplified by PCR and sequenced on both strands.

resultsSequencing detected a novel potential missense mutation (p.Y689N) in the C-terminal proteolytic domain, the mutational hotspot of AFG3L2. The online programme "PolyPhen-2" classifies this amino acid exchange as probably damaging (score 0.990). Similarly to most of the published SCA28 mutations, the novel mutation is located within exon 16. Mutations in exon 16 alter the proteolytic activity of the protease AFG3L2 that is highly expressed in Purkinje cells.

conclusionsGenetic testing should be considered in dominant ataxia with pyramidal tract signs and saccadic slowing.
