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

Arthrogryposis multiplex congenita (AMC) is an important birth defect with a significant genetic contribution. Many syndromic forms of AMC have been described, but remain unsolved at the molecular level. In this report, we describe a novel syndromic form of AMC in two multiplex consanguineous families from Saudi Arabia and Oman. The phenotype is highly consistent, and comprises neurogenic arthrogryposis, microcephaly, brain malformation (absent corpus callosum), optic atrophy, limb fractures, profound global developmental delay, and early lethality. Whole-exome sequencing revealed a different homozygous truncating variant in SCYL2 in each of the two families. SCYL2 is a component of clathrin-coated vesicles, and deficiency of its mouse ortholog results in a severe neurological phenotype that largely recapitulates the phenotype observed in our patients. Our results suggest that severe neurogenic arthrogryposis with brain malformation is the human phenotypic consequence of SCYL2 loss of function mutations.
