Genetic and Environmental Contributors for Celiac Disease

Area of Science:

• Immunology
• Gastroenterology
• Genetics

Background:

• Celiac disease (CD) is an autoimmune disorder triggered by gluten ingestion.
• Genetic predisposition and environmental factors are key to CD development.
• The interplay between genetics, microbiome, and environmental exposures is crucial in CD pathogenesis.

Purpose of the Study:

• To review the primary genetic and environmental factors contributing to celiac disease (CD) pathogenesis.
• To synthesize current knowledge on the complex etiology of CD.
• To explore potential avenues for personalized medicine in CD management.

Main Methods:

• Review of current scientific literature on CD genetics and environmental triggers.
• Analysis of findings from genome-wide association studies (GWAS).
• Examination of recent research on the role of the microbiome and infant feeding practices.

Main Results:

• Genome-wide association studies (GWAS) identified several non-HLA genes implicated in CD.
• HLA haplotype influences infant microbiome composition, and dysbiosis contributes to gluten intolerance.
• Observational studies suggest a protective role for breastfeeding against CD onset.

Conclusions:

• Celiac disease (CD) etiology is multifactorial, involving a complex interaction of genetic and environmental factors.
• Further understanding of these components is essential for elucidating mechanisms of gluten intolerance.
• Insights gained can facilitate the development of personalized medicine strategies for CD.
