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

Chromosome 22q11-13 is one of the most consistent linkage regions for schizophrenia (SCZ) and bipolar disorder (BPAD). The SYNGR1 gene, which is associated with presynaptic vesicles in neuronal cells, is located on 22q13.1. We have previously identified a novel nonsense mutation in the SYNGR1 gene in a SCZ pedigree. In the present study, a detailed analysis of this gene was performed in a case-control cohort (198 BPAD, 193 SCZ and 107 controls from southern India) to test for association with SCZ and BPAD. Sequence analysis of all exonic and flanking intronic regions of the SYNGR1 gene in 198 BPAD and 193 SCZ cases revealed a novel mutation Lsy99Glu (in one BPAD patient) and two other novel common polymorphisms [synonymous single nucleotide polymorphism (SNP--Ser97Ser) and an Asn ins/del] in the SYNGR1 gene. We also validated 9 out of 14 dbSNPs in our population. Case-control analysis revealed allelic (P = 0.028-0.00007) association of five polymorphisms with SCZ and/or BPAD cases. Further, 3-SNP (with LD block 1 SNPs) and 2-SNP (with LD block 2 SNPs) haplotype analyses did not show any association with either SCZ or BPAD. Our results support SYNGR1 as a probable susceptibility gene for SCZ and BPAD. Also, the observed association of SYNGR1 with both SCZ and BPAD suggests the likely involvement of a common pathway in the etiology of these disorders.
