ARC : Deciphering the genetic architecture from oligo- to poylygenic in neurodevelopmental diseases.
Category
Genomics and Genetic BioinformaticsAbout This Project
Even when only one causal mutation is involved, additional genetic variants in small (oligogenic) or large numbers (polygenic) contribute to the disease. Innovative bioinformatics tools are required to decipher this genetic architecture in the complete genome sequencing data.
In this project, the IB2 Bioinformatics Institute and the laboratories of experimental neurology and genetics of the ULB joined forces to detect oligo to polygenic inheritance in abnormalities of brain development, including familial focal epilepsy, childhood epileptic encephalopathies and primary microcephaly, three phenotypes for which researchers have extensive collections of sequencing data. Detected gene interactions will be validated in zebrafish as well as in patients’ iPS cells and in mouse ES cells, using, if necessary, genome engineering technologies.
