Microbiome influences multiple human systems, but its effects on gene methylation is unknown. We investigated the relations between gene methylation in blood and the abundance of common gut bacteria profiled by 16s rRNA gene sequencing in two population-based Dutch cohorts: LifeLines-Deep (LLD, n = 616, discovery) and the Netherlands Twin Register (NTR, n = 296, replication). In LLD, we also explored microbial pathways using data generated by shotgun metagenomic sequencing (n = 683).

(Epi)genomic studies identified SNPs associated with DZ twinning and DNA methylation sites with MZ twinning. To find molecular biomarkers of twinning, we compared transcriptomics and metabolomics data from MZ and DZ twins.

Here, we examined the association of Type D traits with 230 (predominantly) lipid metabolites and metabolite ratios.
Methods: Four Dutch cohorts were included, comprising 10,834 individuals.
Article Synopsis
- * A large study involving nearly 10,000 DCM cases and close to a million controls identified 70 significant genetic locations linked to the disease, revealing the importance of heart muscle cells in its development.
- * The research also indicates that factors like higher body weight and blood pressure may contribute to DCM, and genetic risk scores can help predict the condition across different populations.
