Brief Summary

The main objective of the study is to assess the contribution of whole genome sequencing (WGS) coupled with a multidisciplinary conciliation meeting (MCM) on diagnosis of atypical forms of diabetes co...

Detailed Description

The prevalence of diabetes is 7.4% in France among people aged 20 to 79 years in 2015. We must also consider \"pre-diabetes\" (subjects with glucose intolerance), whose prevalence is equivalen...

Eligibility Criteria

Inclusion

  • Subjects ≥18 years with confirmed diabetes mellitus according to WHO criteria (World Health Organization: Definition and diagnosis of diabetes mellitus and intermediate hyperglycemia: Report of a WHO/IDF Consultation. Geneva, World Health Org., 2006.)
  • Age ≤ 45 years at diabetes diagnosis
  • Body mass index ≤ 35 kg/m² at diabetes diagnosis
  • Negative results of specific antibodies determination (GAD65, IA2, ZnT8) until the inclusion visit
  • Presenting atypical diabetes defined by at least one of the following:
  • Exocrine pancreatic disease
  • Familial history: diabetes diagnosed in first degree relatives from at least 2 generations
  • Notion of familial consanguinity
  • Syndromic clinical features (dysmorphy, developmental delay, mental retardation…) or unusual abnormalities/features that are not part of diabetic complications or co-morbidities;
  • Early occurrence of microvascular complications (≤ 5 years after diabetes diagnosis)
  • Major insulinopenia at diagnosis (C peptide \<0.2 nmol/L and/or documented ketosis)
  • Patient who conserved endogenous insulin secretion (positive C peptide value) but a need for insulin therapy initiation during the first year following diagnosis due to therapeutic failure of well conducted therapeutic intensification
  • Stated willingness to comply with all study procedures and availability for the duration of the study
  • Patient with a social security number in compliance with the French law (dispositions relatives aux recherches impliquant la personne humaine prévues aux articles L 1121-1 et suivants du Code de la Santé Publique)
  • Signed and dated informed consent form

Exclusion

  • Pregnant or breastfeeding woman,
  • Any contraindication to the study exams including known allergies or contraindication to contrasts for the scan
  • Patient with known monogenic diabetes (defined as identification of class 4 and 5 variants according to ACMG)
  • First or second-degree relatives with monogenic diabetes established by molecular genetics (class 4 and 5 variants according to ACMG)
  • Patient with known secondary diabetes (i.e. endocrine disorders such as Cushing syndrome, pancreatectomy, drug-induced diabetes)
  • Any condition which in the Investigator's opinion makes it undesirable for the subject to participate in the trial or which would jeopardize compliance with the protocol,
  • Individuals under legal protection (sauvegarde de justice).
