Using data for more than a million individuals with or without insomnia, two independent research teams tracked down associated risk loci and explored their functional effects.
Researchers used fine mapping and other approaches to prioritize proposed coding and non-coding causal variants at rheumatoid arthritis- and type 1 diabetes-linked loci.
These differentially variable positions appear to implicate stress response in rheumatoid arthritis development and possibly in other autoimmune conditions.
A heterozygous variant upstream of the BRCA1 translation start site was uncovered in all individuals in these two families with hypermethylated BRCA1 promoters.
An integrated analysis of 30 soil microbiome datasets suggests that common bacterial taxa may be less useful ecological indicators compared to much rarer taxa.
