Development of statistical methods to detect epistasis in Genome-Wide Association Studies.

Co-direction : Christophe Ambroise et Cyril Dalmasso



Research topics

  • Genome-Wide association studies.
  • Epistasis, gene-gene interaction.
  • Structured penalized regression models


  • Group Lasso Gene-Gene Eigen Epistasis (GGEE) :

The GGEE package implements the group lasso Gene-Gene Eigen Epistasis (G-GEE) method for detecting epistasis at the gene level. The proposed functions allow to compute interaction variables for each pair of gene and to fit a general model with a Group Lasso penalty. The package allows to generate gene structured genotype data and continuous phenotype. The package is available from github and can be installed as follows from within R:

# install.packages("devtools")
