Activity


The Inserm U1245, composed of 2 teams “Cancer genetics” and “Neurogenetics”, is focused on the study of hereditary predisposition to colorectal cancer and pediatric tumours, somatic genetics and targeted therapies of colorectal cancer, genetics and physiopathology of dementias and RNA diseases (splicing and microARNs). The projects are based on national recruitment of patients and strong interactions with many French and European groups. The unit has a strong commitment in the translational research and technological transfer with the development of new methods to detect and interpret genetic variations.


Main Contributions


  •  Development of the QMPSF method allowing routine detection of germline and somatic quantitative genomic alterations
  • Development of ex vivo splicing assays allowing to reclassify unclassified genetic variations as splicing mutations
  • Characterisation of the molecular bases of hereditary non polyposis colorectal cancer and of the genetic predisposition to childhood cancers
  • Identification of molecular markers of resistance or sensitivity to targeted therapies in colorectal cancer
  • Detection of the APP duplication in Alzheimer disease
  • Identification by genetic screen in Drosophila of modifiers of tau-induced neurotoxicity
  • Role of hyperprolinemia in psychoses and mental retardation
  • Role of gene dosage variation in psychoses and mental retardation
  • Development in collaboration with the Interactive Biosftware company of the Alamut software suite for the analysis of nucleotide variations
