Description

Yong Zeng and co-authors present a new way to find genes whose activity is steered jointly by a DNA variant and a chemical tag on the DNA, in a 2023 paper. Standard studies link variants to gene activity but ignore methylation, the tag in question. The team had earlier verified one case where the tag changed a variant's effect, and now they test how common the pattern is.

Their method, called memo-eQTL mapping, was applied to 128 healthy prostate samples. It surfaced 1,063 variant-gene pairs governed this way, most of them invisible to standard mapping. The tag can strengthen the variant's grip on the gene or shield the gene from it, by reshaping how the DNA folds in three dimensions around a key structural protein. The authors argue this hidden layer points to new causal genes behind traits and diseases tied to DNA variants.
