Genetic Variations in Vitamin D Metabolism Linking Epigenetic Regulation and Microbiota Interactions: From Phenotype to Genotype.

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
backgroundVitamin D deficiency is a global health concern affecting all age groups, despite the implementation of supplementation strategies. This study aimed to investigate the roles of genetic polymorphisms, epigenetic mechanisms, and microbiota interactions in vitamin D metabolism, as well as their potential contributions to allergies, autoimmune thyroiditis, and autism spectrum disorder.
methodsThis retrospective, descriptive study analyzed data from 60 individuals (16 males and 44 females) who underwent nutrigenetic testing between 2022 and 2024 at Epigenetic Coaching, Istanbul, Turkey. Genetic analyses focused on the cytochrome P450 family 2 subfamily R member 1 (CYP2R1) gene, group-specific component (GC) gene, and vitamin D receptor (VDR) polymorphisms. Inclusion criteria included the presence of allergic symptoms, a diagnosis of autism spectrum disorder, or a diagnosis of Hashimoto's thyroiditis, along with prior genetic testing for the selected variants. Individuals with any known genetic disorder other than the studied variants were excluded.
resultsCYP2R1, GC, and VDR polymorphisms associated with vitamin D insufficiency were found at higher frequencies in patients with autism, Hashimoto's thyroiditis, and allergic conditions. When examining the associations between genetic variants and diseases, VDR FokI, VDR ApaI, and VDR BsmI variants were more frequently observed in patients with Hashimoto's thyroiditis, while the VDR TaqI variant was more common in individuals with autism. In the allergy group, BsmI, FokI, ApaI, and TaqI variants were identified at higher frequencies.
conclusionGenetic variants and epigenetic modifications may disrupt vitamin D metabolism and alter gut microbiota diversity, contributing to the development of various diseases. Evaluating vitamin D deficiency together with its genetic, epigenetic, and microbiota determinants is essential for developing effective prevention and treatment strategies. These findings emphasize the necessity of personalized, nutrigenetic-based approaches to optimize vitamin D function and support overall health.
