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

Autosomal-recessive primary microcephaly (MCPH) is a rare congenital disorder characterized by intellectual disability, reduced brain and head size, but usually without defects in cerebral cortical architecture, and other syndromic abnormalities. MCPH is heterogeneous. The underlying genes of the seven known loci code for centrosomal proteins. We studied a family from northern Pakistan with two microcephalic children using homozygosity mapping and found suggestive linkage for regions on chromosomes 2, 4, and 9. We sequenced two positional candidate genes and identified a homozygous frameshift mutation in the gene encoding the 135 kDa centrosomal protein (CEP135), located in the linkage interval on chromosome 4, in both affected children. Post hoc whole-exome sequencing corroborated this mutation's identification as the causal variant. Fibroblasts obtained from one of the patients showed multiple and fragmented centrosomes, disorganized microtubules, and reduced growth rate. Similar effects were reported after knockdown of CEP135 through RNA interference; we could provoke them also by ectopic overexpression of the mutant protein. Our findings suggest an additional locus for MCPH at HSA 4q12 (MCPH8), further strengthen the role of centrosomes in the development of MCPH, and place CEP135 among the essential components of this important organelle in particular for a normal neurogenesis.
