rs168753
Variant in the F2R gene (Coagulation Factor II Thrombin Receptor (PAR1))
rs168753 is a single nucleotide polymorphism (SNP) in the F2R gene, involved in thrombin signaling / platelet activation / endothelial. Variants at this position have been studied in relation to immune function, metabolism, and chronic illness.

What is the rs168753 variant?
rs168753 is a SNP (single nucleotide polymorphism) in the F2R (Coagulation Factor II Thrombin Receptor (PAR1)) gene. It belongs to the Coagulation category and is part of the Coagulation & Microcirculation biological cluster. F2R encodes PAR1 (protease-activated receptor 1), the main thrombin receptor on platelets and endothelial cells.
Biological role and pathway
This variant sits within the F2R gene, which is involved in the thrombin signaling / platelet activation / endothelial pathway. 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 — particularly under conditions of physiological stress such as viral infection or prolonged illness.
rs168753 and Long COVID / ME-CFS research
PAR1 mediates thrombin-driven platelet activation and endothelial inflammation; variants may affect the thrombotic and inflammatory response to coagulation dysregulation in Long COVID.

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 F2R and the rs168753 variant.
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.
Frequently asked questions
What is the rs168753 variant in the F2R gene?
rs168753 is a single nucleotide polymorphism (SNP) located in the F2R (Coagulation Factor II Thrombin Receptor (PAR1)) gene, which is involved in thrombin signaling / platelet activation / endothelial. F2R encodes PAR1 (protease-activated receptor 1), the main thrombin receptor on platelets and endothelial cells.
How may the rs168753 variant relate to Long COVID or ME/CFS?
PAR1 mediates thrombin-driven platelet activation and endothelial inflammation; variants may affect the thrombotic and inflammatory response to coagulation dysregulation in Long COVID.
Can a consumer DNA test detect the rs168753 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.
