[MODY type diabetes: overview and recent findings]

Area of Science:

• Endocrinology
• Genetics
• Molecular Biology

Context:

• Maturity onset diabetes of the young (MODY) is the most prevalent form of monogenic diabetes, characterized by autosomal dominant inheritance.
• It presents heterogeneously worldwide, typically diagnosed before 25 years of age and is non-ketotic.
• Despite significant progress, the full genetic landscape of MODY remains incompletely understood.

Purpose:

• To provide an updated overview of MODY, incorporating recent molecular discoveries and evolving diagnostic approaches.
• To consolidate current knowledge on the molecular basis, phenotypic variations, and epidemiological distribution of MODY subtypes.
• To highlight the ongoing need for further research to identify novel genetic factors associated with MODY X.

Summary:

• MODY is a genetically diverse condition with at least seven identified genes, though subtypes 2 and 3 are most common globally.
• Molecular abnormalities underlying MODY lead to varied phenotypic consequences, necessitating precise diagnostic strategies.
• Understanding the epidemiology and molecular diagnosis of each MODY subtype is crucial for optimizing patient care.

Impact:

• Enhanced understanding of MODY's genetic architecture facilitates more accurate diagnosis and personalized treatment strategies.
• This knowledge update aids clinicians in differentiating MODY from other diabetes types, improving patient management.
• Continued research into MODY genetics promises to uncover new therapeutic targets and diagnostic markers for rare diabetes forms.
