rs1800449

What is the rs1800449 variant?

rs1800449 is a SNP (single nucleotide polymorphism) in the LOX (Lysyl Oxidase) gene. It belongs to the Connective Tissue category and is part of the Coagulation & Microcirculation biological cluster. LOX encodes lysyl oxidase, the enzyme that cross-links collagen and elastin fibers to provide tensile strength to connective tissues.

Biological role and pathway

This variant sits within the LOX gene, which is involved in the collagen and elastin crosslinking 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.
