GSTM1 copy number variation in the context of single nucleotide polymorphisms in the human GSTM cluster.
Article in Molecular cytogenetics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
backgroundGSTM1 gene deletion is one of the most known copy number polymorphisms in human genome. It is most likely caused by homologous recombination between the repeats flanking the gene. However, taking into account that the deletion has no crucial effects on human well-being, and the ability of other GSTMs to compensate for the lack of GSTM1, a role for additional factors affecting GSTM1 deletion can be proposed. Our goal was to explore the relationships between GSTM1 deletion polymorphism and single nucleotide polymorphisms (SNPs) in the region of the GSTM cluster that includes GSTM2, GSTM3, GSTM4, and GSTM5 in addition to GSTM1.
resultsReal-time polymerase chain reaction was used to quantify the number of GSTM1 copies. Fourteen SNPs from the region were tested and their allelic patterns were compared in groups of Russian individuals subdivided according to their GSTM1 deletion genotypes. Linkage disequilibrium-based haplotype analysis showed substantial differences of haplotype frequencies between the groups, especially between individuals with homozygous GSTM1 -/- and +/+ genotypes. Exploration of the results of phasing of GSTM1 and SNP genotypes revealed unequal segregation of GSTM1 + and - alleles at different haplotypes.
conclusionsThe observed differences in haplotype patterns suggest the potential role of genetic context in GSTM1 deletion frequency (appearance) and in the determination of the deletion-related effects.
