rs1802458

What is the rs1802458 variant?

rs1802458 is a SNP (single nucleotide polymorphism) in the CDH5 (Cadherin 5 (VE-Cadherin)) gene. It belongs to the Vascular category and is part of the Coagulation & Microcirculation biological cluster. CDH5 encodes VE-cadherin, the primary component of endothelial adherens junctions that regulates vascular permeability.

Biological role and pathway

This variant sits within the CDH5 gene, which is involved in the endothelial adherens junction / vascular permeability 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.
