Susceptibility genes for the development of SLE during treatment of IBD

A potential and very serious side effect of treating IBD with antiTNFa therapies (the current gold standard) is the development of systemic lupus erythematosis (SLE). This side effect is rare and unpredictable. Out of several thousand cases having received treatment, the University of Calgary have accumulated 12 individuals with full phenotyping and novel serological antibody discovery panel data. We propose to exome sequence these samples in an effort to identify rare highly-penetrant variants that could be underlying this severe phenotype.EGA study EGAS00001000387
