rs4898

What is the rs4898 variant?

rs4898 is a SNP (single nucleotide polymorphism) in the TIMP1 (TIMP Metallopeptidase Inhibitor 1) gene. It belongs to the Connective Tissue category and is part of the Coagulation & Microcirculation biological cluster. TIMP1 encodes the primary endogenous inhibitor of matrix metalloproteinases, regulating ECM degradation and tissue remodeling.

Biological role and pathway

This variant sits within the TIMP1 gene, which is involved in the MMP inhibition / ECM homeostasis 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.
