rs516115

What is the rs516115 variant?

rs516115 is a SNP (single nucleotide polymorphism) in the DCN (Decorin) gene. It belongs to the Connective Tissue category and is part of the Coagulation & Microcirculation biological cluster. DCN encodes decorin, a small leucine-rich proteoglycan that organizes collagen fibril assembly and sequesters TGF-beta.

Biological role and pathway

This variant sits within the DCN gene, which is involved in the TGF-beta regulation / collagen fiber organization 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.
