IL12RB2 Gene

What is the IL12RB2 gene?

IL12RB2 encodes interleukin 12 receptor subunit beta 2, a protein involved in IL-12 / Th1 differentiation. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. IL12RB2 encodes the beta-2 subunit of the IL-12 receptor, essential for IL-12-driven Th1 differentiation and IFN-gamma production.

Biological role and pathway

IL12RB2 is involved in the IL-12 / Th1 differentiation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Immune System & Inflammation cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the IL12RB2 gene have been studied in relation to immune signaling and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs3790567— IL12RB2 variant
• rs2307148— IL12RB2 variant

Genetic insights from DNA data

Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include IL12RB2 and related genes in the immune system & inflammation pathway.

The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.
