What is the rs28931588 variant?
rs28931588 is a SNP (single nucleotide polymorphism) in the THBD (Thrombomodulin) gene. It belongs to the Coagulation category and is part of the Coagulation & Microcirculation biological cluster. THBD encodes thrombomodulin, an endothelial surface protein that binds thrombin and converts it to an activator of protein C, switching from procoagulant to anticoagulant.
Biological role and pathway
This variant sits within the THBD gene, which is involved in the anticoagulation / protein C activation 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.
rs28931588 and Long COVID / ME-CFS research
Thrombomodulin shedding from endothelium occurs in COVID-19 and Long COVID, impairing anticoagulation; THBD variants may affect the balance between coagulation and anticoagulation.

Frequently asked questions
What is the rs28931588 variant in the THBD gene?
rs28931588 is a single nucleotide polymorphism (SNP) located in the THBD (Thrombomodulin) gene, which is involved in anticoagulation / protein C activation. THBD encodes thrombomodulin, an endothelial surface protein that binds thrombin and converts it to an activator of protein C, switching from procoagulant to anticoagulant.
How may the rs28931588 variant relate to Long COVID or ME/CFS?
Thrombomodulin shedding from endothelium occurs in COVID-19 and Long COVID, impairing anticoagulation; THBD variants may affect the balance between coagulation and anticoagulation.
Can a consumer DNA test detect the rs28931588 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.
