What is the rs1793953 variant?

rs1793953 is a SNP (single nucleotide polymorphism) in the COL2A1 (Collagen Type II Alpha 1 Chain) gene. It belongs to the Connective Tissue category and is part of the Coagulation & Microcirculation biological cluster. COL2A1 encodes type II collagen, the major structural component of cartilage and vitreous body.

Biological role and pathway

This variant sits within the COL2A1 gene, which is involved in the cartilage ECM / structural integrity 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.

rs1793953 and Long COVID / ME-CFS research

Type II collagen integrity is important for joint function; COL2A1 variants may affect cartilage resilience and contribute to musculoskeletal symptoms in Long COVID.
