Genomics andAutoimmunologiczne choroby: A Deepening Picture

Genomics - the underpursive study of an organism 's complete DNA sequence - has revolutizized autoime research. Unlike single-gne disorders, most autoimty conditions are polygenic, involving dozens or hundreds of genetic variants, each contribuing a small effect. Large- scale genome-wide asociation studios (GWAS) have identified over 300 risk loci across major autoimty diseaseaseasees. Many of these loci cluster in pathalways central témentation, includintiltiltag antigen presention, T-cell signalnyindignaling, T-cell, cying, cytokine production.

Advanced sequencing technologies, such as whole-exome and whole-genome sequencing, are also uncovering rare, large-effect variants that modulate disease risk.

Environmental Triggers andGene-Environmental Interactions

Genomys alone does does dictine destiny.
