Overview

The goal of this observational study consists of performing cluster analysis to decipher underlying disease mechanisms of type 1 diabetes in children and young adults.

To this end, we will combine clinical, laboratory, genetic, transcriptomic, and metabolomic datasets of an extensively phenotyped cohort of children and young adults with type 1 diabetes. We will also assess the risk for cardiovascular diseases in this most vulnerable diabetes cohort.
