Brief Summary:
G (guanine nucleotide binding) proteins associating with G protein-coupled receptors (GPCR) are key players in the pathogenesis of obesity and diabetes and are targets of pharmacotherapeutic inter-ventions. In addition, G proteins binding to GPCRs either directly or permissively determine the efficacy of lifestyle interventions and drugs aiming at weight management and diabetes treatment. Polymor-phisms of the fat mass and obesity-related protein (FTO) gene have been also well characterised and linked to energy intake, body fat mass as well as CVD risk and the susceptibility to weight-reducing interventions. Stratifying patients according to G protein and FTO-related genotyping may enable a more accurate prediction of individual disease courses and responses to therapeutic interventions in terms of safety and tolerability as well as efficacy. Although the objectives primarily refer to the analysis of G pro-tein and FTO-related genotypes, also other genes of potential relevance for the evolution of obesity and/ or diabetes and the response to lifestyle and pharmacological interventions may be analysed.

Group/Cohort
Healthy volunteers
Considered generally healthy based on medical history and physical examination as per discretion of the investigator
Type 1 Diabetes
T1DM diagnosed clinically prior to start of trial examinations
Type 2 Diabetes
T2DM diagnosis prior to the start of trial examinations



Primary Outcome Measures :
  1. Association of defined G protein- and FTO-related genotypes with the presence of T2DM or T1DM from a blood sample; also other genes of potential relevance for the evolution of obesity and/or diabetes. [ Time Frame: day 1 ]

Secondary Outcome Measures :
  1. Association of defined G protein- and FTO-related genotypes with the T2DM risk of healthy volunteers from a blood sample. [ Time Frame: day 1 ]

Biospecimen Retention:   Samples With DNA
whole blood samples
