Comprehensive characterization of pathogenic missense CTRP6 variants and their association with cancer.
Article in BMC cancer, 2025. 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
backgroundPrevious genome-wide association studies have linked three missense single nucleotide polymorphisms (SNPs) in C1q/TNF-related protein 6 (CTRP6) to diseases such as type 1 diabetes and autoimmune diseases. However, the potential association of newly identified missense CTRP6 variants with diseases, especially cancer, remains unclear.
methodsWe used several pathogenicity prediction algorithms to identify deleterious mutations within the highly conserved C1q domain of human CTRP6, following the retrieval of all SNPs from the Ensembl database. We systematically analyzed the effects of these mutations on the protein's stability, flexibility, structural conformation, compactness, stiffness, and overall functionality using various bioinformatics tools. Additionally, we investigated the association of these mutations with different cancer types using the cBioPortal and canSAR databases.
resultsWe identified 11 detrimental missense SNPs within the C1q domain, a region critical for this protein's functionality. Using various computational methods, we predicted the functional impact of these missense variants and assessed their effects on the stability and flexibility of the CTRP6 structure. Molecular dynamics simulations revealed significant structural differences between the native and mutated structures, including changes in structural conformation, compactness, solvent accessibility, and flexibility. Additionally, our study shows a strong association between two mutations, G181S and R247W, and certain types of cancer: colon adenocarcinoma and uterine corpus endometrial carcinoma, respectively. We also found that the mutational status of CTRP6 and other cancer-related genes, such as MAP2K3, p16, TP53, and JAK1, affected each other's expression, potentially contributing to cancer development.
conclusionsOur screening and predictive analysis of pathogenic missense variants in CTRP6 advance the understanding of the functional implications of these mutations, potentially facilitating more focused and efficient research in the future.
