What is the rs3110697 variant?
rs3110697 is a SNP (single nucleotide polymorphism) in the IGFBP3 (Insulin-Like Growth Factor Binding Protein 3) gene. It belongs to the Neuroendocrine category and is part of the Metabolic Regulation biological cluster. IGFBP3 encodes the major carrier of circulating IGF-1, extending its half-life and modulating its bioavailability.
Biological role and pathway
This variant sits within the IGFBP3 gene, which is involved in the IGF bioavailability regulation pathway. Genes within the Metabolic Regulation 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.
rs3110697 and Long COVID / ME-CFS research
IGFBP3 regulates IGF-1 bioavailability; variants may affect the effective IGF-1 levels available for tissue repair and anabolic functions in Long COVID.

Frequently asked questions
What is the rs3110697 variant in the IGFBP3 gene?
rs3110697 is a single nucleotide polymorphism (SNP) located in the IGFBP3 (Insulin-Like Growth Factor Binding Protein 3) gene, which is involved in IGF bioavailability regulation. IGFBP3 encodes the major carrier of circulating IGF-1, extending its half-life and modulating its bioavailability.
How may the rs3110697 variant relate to Long COVID or ME/CFS?
IGFBP3 regulates IGF-1 bioavailability; variants may affect the effective IGF-1 levels available for tissue repair and anabolic functions in Long COVID.
Can a consumer DNA test detect the rs3110697 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.
