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

purposeTo identify the potential pathogenic mutation over four generations of a Chinese family with congenital anterior polar cataracts (APC).

methodsWe investigated four generations of a Chinese family who are afflicted with anterior polar cataracts. The family resides in a relatively isolated region of Northern China. Peripheral blood samples were collected from all of the family members, and genomic DNA was then extracted from the blood samples. A gene scan was performed using about 400 primers labeled with fluorescent stain. Linkage software defined the region of the diseased gene with a Linkage analysis, and Cyrillic software processed the resulting haplotypes. Mutation detection was performed in the candidate gene by sequencing amplified products.

resultsA maximum logarithm of odds score (LOD) score was obtained at marker D21S1252(LOD score [Z]=3.23, recombination fraction [θ]=0.0. Haplotype analysis traced the disease gene to an 18.47 cM region bounded by D21S263 and D21S266 on chromosome21q22.11-q22.3. Direct sequencing of the candidate alpha A crystallin (CRYAA) gene revealed a c.347G>A transition in exon 3 of CRYAA that co-segregated with the cataract in the family members and was not observed in 100 control patients. This single-nucleotide change resulted in the substitution of a highly conserved Arginine by Histidine (R116H).

conclusionsThe present study identified a missense mutation (R116H) in the CRYAA gene that causes autosomal dominant congenital anterior polar cataracts in a Chinese family. Our finding confirms the high rate of apparently independent mutations at this dinucleotide.
