Genetic and Environmental Risk Factors of Type 1 Autoimmune Diabetes and Its Early Complications (ISIS-DIAB)

Read time: 1 mins
Last updated:6th Aug 2014

The aim of this study is to complete the identification of genetic factors (G) and to undertake the search of environmental factors (E) predisposing to type 1 diabetes (T1D) by constituting a cohort of 3500 T1D patients and a control cohort. We will use the base of G analysis (whole genome genotyping done once a patient using methods conually updated at Centre National de Genotype) and innovative E analysis to develop the following long term objectives :

- Identify G and E factors influencing the process of remaining beta cells' destruction during the first 3 years after diagnosis (subgroup of T1D patients with a 0-3 years diabetes duration);

- Identify G factors (pharmacogenomics) of the individual response to insulin using the effective insulin dose as a phenotype over a period of 2 years (subgroup of T1D patients with negative C-peptide and well managed diabetes);

- Undertake a prospective research of G and E risk factors of "death in bed" syndrome in diabetic adolescents;

- Undertake a prospective research of G and E risk factors of incipient glomerular microangiopathy (regule measurement of microalbuminuria).
