FGF2 Gene

Fibroblast Growth Factor 2 (Basic FGF) (FGF2) is a gene involved in FGF receptor / angiogenesis / tissue repair that has been studied in relation to immune function, metabolism, and chronic illness. Variants in FGF2 may influence how the body responds to infection, inflammation, and long-term recovery.

What is the FGF2 gene?

FGF2 encodes fibroblast growth factor 2 (basic fgf), a protein involved in FGF receptor / angiogenesis / tissue repair. It belongs to the Signaling category and is part of the Coagulation & Microcirculation biological cluster. FGF2 encodes basic FGF, a potent angiogenic and tissue repair factor that promotes endothelial cell proliferation.

Biological role and pathway

FGF2 is involved in the FGF receptor / angiogenesis / tissue repair pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Coagulation & Microcirculation 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.

FGF2 and Long COVID / ME-CFS research

FGF2 drives angiogenesis and tissue repair after injury; variants may affect vascular repair and tissue regeneration in Long COVID-related organ damage.

Known genetic variants

The following variants (SNPs) in the FGF2 gene have been studied in relation to signaling and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

Conditions studied in relation to FGF2

Research into FGF2 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that FGF2 causes or treats any condition.

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 FGF2 and related genes in the coagulation & microcirculation 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.
