The frequency of known germline LGR4 missense variant in the ethnic groups of West Siberia.
Article in Molecular biology reports, 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
backgroundHereditary breast cancer is an autosomal dominant disease caused by variants in genes such as BRCA1/2, RAD51, ATM, BRIP1, and others. In a previous study using whole exome sequencing, we identified a germline variant of the LGR4 gene (rs34804482, NM_018490.5(LGR4):c.2531 A > G (p.Asp844Gly)) in a young Tuvan breast cancer patient (belonging to the Turkic-speaking tribes of Central Asia). The aim of this study was to determine the frequency of the variant of the LGR4 gene NM_018490.5(LGR4):c.2531 A > G (p.Asp844Gly) in ethnic groups of West Siberia using the PCR-RT method.
methodsThe study involved 735 breast cancer patients from ethnic groups in Siberia, median age at diagnosis of 43 ± 15.6 years. The control group consisted of 727 healthy women from Siberia, median age of 43.05 ± 13.5 years.
resultsThe frequency of this variant (rs34804482) was 0.015 in Russian, 0.022 in Buryat, and 0.069 in Tuvan breast cancer patients. In Tuvan women with breast cancer, the frequency of the LGR4 gene variant was significantly higher than in Russian BC patients (0.069 versus 0.015, X
conclusionsWe found no statistically significant differences in the rs34804482 frequency between breast cancer patients and healthy individuals in the ethnic groups studied. The highest frequency of this missense germline variant was observed among Tuvans.
