rs1495965
Variant in the IL23R gene (Interleukin 23 Receptor)
rs1495965 is a single nucleotide polymorphism (SNP) in the IL23R gene, involved in IL-23 / Th17 axis. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs1495965 variant?
rs1495965 is a SNP (single nucleotide polymorphism) in the IL23R (Interleukin 23 Receptor) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. IL23R encodes the receptor for IL-23, a cytokine critical for Th17 cell maintenance and effector function.
Biological role and pathway
This variant sits within the IL23R gene, which is involved in the IL-23 / Th17 axis 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.
rs1495965 and Long COVID / ME-CFS research
IL23R variants are the strongest genetic determinants of susceptibility to Th17-mediated autoimmune diseases (IBD, psoriasis); these pathways may contribute to the autoimmune features of Long COVID.

The following variants in IL23R are also studied in relation to chronic illness and may be analysed together for a more complete picture.
Frequently asked questions
What is the rs1495965 variant in the IL23R gene?
rs1495965 is a single nucleotide polymorphism (SNP) located in the IL23R (Interleukin 23 Receptor) gene, which is involved in IL-23 / Th17 axis. IL23R encodes the receptor for IL-23, a cytokine critical for Th17 cell maintenance and effector function.
How may the rs1495965 variant relate to Long COVID or ME/CFS?
IL23R variants are the strongest genetic determinants of susceptibility to Th17-mediated autoimmune diseases (IBD, psoriasis); these pathways may contribute to the autoimmune features of Long COVID.
Can a consumer DNA test detect the rs1495965 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.
