Genetic Predisposition to Autoimmune Diabetes Mellitus

Area of Science:

• Immunology
• Genetics
• Endocrinology

Background:

• Type 1 diabetes mellitus (T1DM) is a multifactorial autoimmune disease with increasing global incidence.
• Genetic predisposition combined with environmental factors triggers T1DM, but specific triggers remain elusive.
• Identifying at-risk populations is challenging due to the lack of a single identifiable cause.

Purpose of the Study:

• To review current data on the genetic and epigenetic factors contributing to autoimmune diabetes.
• To analyze regional and ethnic variations in T1DM incidence.
• To explore the potential of clinical-genetic models for disease prediction and personalized therapy.

Main Methods:

• Systematic review of existing literature on T1DM genetics and epigenetics.
• Analysis of epidemiological data on T1DM incidence globally and within the Russian Federation.
• Assessment of bioinformatics and epigenetic research advancements.

Main Results:

• T1DM exhibits significant genetic and epigenetic heterogeneity.
• Environmental factors play a crucial role in activating genetic predispositions.
• Regional and ethnic disparities in T1DM incidence are evident.

Conclusions:

• Bioinformatics and epigenetic research provide novel opportunities for T1DM early diagnosis and prevention.
• Understanding molecular pathways can lead to algorithms for early diagnosis, prognosis, and personalized treatment.
• Clinical-genetic models hold promise for predicting T1DM risk and guiding therapeutic strategies.
