What is the rs1929992 variant?
rs1929992 is a SNP (single nucleotide polymorphism) in the IL33 (Interleukin 33) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. IL33 encodes interleukin-33, an alarmin cytokine released by damaged cells that activates mast cells, ILC2s, and T cells via the ST2 receptor.
Biological role and pathway
This variant sits within the IL33 gene, which is involved in the alarmin / IL-33-ST2 signaling pathway. 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 — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs1929992 and Long COVID / ME-CFS research
IL-33 is an alarmin released upon tissue damage; elevated IL-33 signaling may contribute to mast cell activation, type-2 inflammation, and MCAS-like features in Long COVID.

Frequently asked questions
What is the rs1929992 variant in the IL33 gene?
rs1929992 is a single nucleotide polymorphism (SNP) located in the IL33 (Interleukin 33) gene, which is involved in alarmin / IL-33-ST2 signaling. IL33 encodes interleukin-33, an alarmin cytokine released by damaged cells that activates mast cells, ILC2s, and T cells via the ST2 receptor.
How may the rs1929992 variant relate to Long COVID or ME/CFS?
IL-33 is an alarmin released upon tissue damage; elevated IL-33 signaling may contribute to mast cell activation, type-2 inflammation, and MCAS-like features in Long COVID.
Can a consumer DNA test detect the rs1929992 variant?
Many consumer DNA tests such as 23andMe, AncestryDNA, and MyHeritage genotype common SNPs. ChronicDNA analyses your raw DNA file and reports on variants studied in relation to chronic illness, immune function, and metabolism. This is not a diagnostic service — results are informational and educational only.
