Investigation of an MCM8 gene variant in women with premature ovarian insufficiency.
Article in Einstein (Sao Paulo, Brazil), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe MCM8 gene is involved in the homologous recombination and repair of double-stranded DNA breaks. It maintains the meiotic process continuously. If the MCM8-9 helicase does not function, the accumulation of DNA breaks can result in cell death. Studies have reported MCM8 gene suppression with primary ovarian insufficiency. In the present study, a variant of the MCM8 gene was investigated in women with primary ovarian insufficiency to elucidate the role of MCM8 in this pathology.
objectiveTo evaluate the frequency of the NG_042869.1:g.40270G>A variant of the MCM8 gene in the study population.
methodsThe MCM8 gene variant was analyzed via real-time polymerase chain reaction using a hydrolysis probe in DNA samples from women diagnosed with primary ovarian insufficiency, with a normal karyotype and without FMR1 gene permutation, and from a Control Group, who had menopause after 50 years of age. Frequencies were compared using Fisher's exact test.
resultsA total of 100 samples from the Case Group and 100 samples from the Control Group were selected. The variant was detected in heterozygosity in a Case Group sample but was not identified in the Control Group. DISCUSSION: This variant was first described in a consanguineous Arab family. This variant is classified as pathogenic and has a prevalence of 1% in women with primary ovarian insufficiency. This study is a pioneering investigation of this variant in Brazilian women.
conclusionThese findings suggest that the rs138761187 variant of the MCM8 gene is rare in Brazilian women.
