Description
Genome-wide association studies have established statistical associations between various diseases and a large number of single-nucleotide polymorphisms (SNPs). However, they provided no simple explanation of the mechanisms underlying this association.
Following the idea that 3D genome organization and its variations may have a functional role in gene regulation, we investigated the distribution of these SNPs with respect to topologically-associating domains (TADs) and their borders. Our computational analyses show that for some specific diseases, including many cancers, disease-associated SNPs are over-represented in TAD borders.
To analyze further this enrichment, its determinants and its consequences, we have selected candidate loci and started an experimental study using two techniques (HRS-seq and 3C-qPCR) developed in the group at IGMM.
Work in collaboration with Thierry Forné (IGMM, Montpellier, France), Julien Mozziconacci (MNHN & LPTMC , Paris, France), Marc-Torsten Hütt (Jacobs University, Bremen, Germany) and their students Marina Villaverde, Coralie Compare, Leopold Carron (now at LCQB, Paris) and Kim Philipp Jablonski (now at ETH, Zürich).
