Specificities of Atypical Non AutoImmune Diabetes (ANAID) in the French West Indies (DiAGeNA)

May 4, 2026 updated by: Centre Hospitalier Universitaire de la Guadeloupe

Epidemiological, Clinical, Biological and Genetic Specificities of Atypical Non-AutoImmune Diabetes (ANAID) in the French West Indies

Genetics variants could be involved in atypical non-autoimmune diabetes revealed by ketoacidosis. The objective of this research will be to determine the relationships between the genetic variants already described in known monogenic diabetes or identified as involved in glucose metabolism and its regulation, in insulin signaling pathways or in insulin secretion itself in subjects of African and Indian ancestry with atypical forms of non autoimmune diabetes.

Detailed Description

In the French West Indies, the prevalence of diabetes is twice as high as that reported at the national level with a clinical and biological phenotype which seems different, undoubtedly linked to genetic polymorphisms sometimes correlated with specific environmental exposures in these territories. The two most common forms of diabetes are type 1 diabetes (T1D), which accounts for around 5 - 10% of all diabetes, and type 2 diabetes (T2D), which is much more common (around 90 - 95 %). However, in practice, forms of atypical diabetes are described more and more frequently in young subjects, without an autoimmune context, occurring in a family context or not, without the classic phenotype of common type 2 diabetes with the observation in certain populations episodes of ketoacidosis which can be life-threatening. Genetic variants involved in glucose metabolism and its regulation, in insulin signaling pathways, or insulin secretion itself could explain the occurrence of this type of diabetes or episodes of ketoacidosis in these subjects with an evolution towards more or less early insulin withdrawal. The genetic sampling, which is part of the routine etiological diagnosis of these atypical forms, will be carried out with clinical and metabolic evaluation carried out as part of routine care. Unfortunately, this genetic research is not always done systematically. This is a multicenter prospective observational study. This research will be cross-sectional in order to identify in subjects presenting forms of atypical non-autoimmune diabetes (DNAI) found in subjects of African and Indian ancestry in the French West Indies, the presence of known pathogenic mutations described in monogenic diabetes of the MODY type (GCK, HNF1A, HNF4A, PDX1, HNF1B, NEUROD1, CEL, INS, ABCC8, KCNJ11, GATA6, WFS1, TRMT10A, PCBD1, GATA4, APPL1, RFX6, MAFA, SLC19A2, ONECUT1, m.3243A>G, KCNK16) but also new mutations in genes involved in glucose metabolism and its regulation, in insulin signaling pathways, or insulin secretion and this thanks to a molecular screening of the entire exome. A longitudinal follow-up is secondarily planned in order to determine the appearance of complications according to the presence of pathogenic genetic mutations that will have been identified.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
