Variability in the PRDM9 gene in Sindhi cattle.
Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSindhi is a dual-purpose breed adapted to tropical environments. However, this breed has the smallest total population among indicine breeds in Brazil and the smallest effective number. In addition, the inbreeding coefficient is higher than 6.25% in ~ 60% of the population. Therefore, alternatives to increase genetic diversity are important. Within this context, the PRDM9 gene is particularly interesting since it is involved in meiotic recombination events, consequently enhancing genetic variability in the population by increasing the number of circulating haplotypes. Each allele of the gene induces recombination at a different hotspot. The larger the number of circulating alleles, the higher the recombination rate and the greater the genetic variability.
methodsThe aim of this study was to characterize alleles of the PRDM9 gene in Sindhi cattle. The region of the zinc finger domains of the gene was amplified by PCR, genotyped, and sequenced for allele identification in 50 Sindhi animals.
resultsThree alleles (A-cattle1, B-cattle14, and C-cattle19) and six genotypes (AA, BB, CC, AB, AC, and BC) were identified.
conclusionThe allele variation of the PRDM9 gene in the Sindhi breed enables to guide the mating of animals with different genotypes/alleles and to promote genetic variability by recombination if there is intralocus variability.
