rs11575939

What is the rs11575939 variant?

rs11575939 is a SNP (single nucleotide polymorphism) in the CD163 (CD163 Molecule) gene. It belongs to the Immune Signaling category and is part of the Immune System & Inflammation biological cluster. CD163 encodes a scavenger receptor on alternatively activated (M2) macrophages, regulating hemoglobin-haptoglobin clearance.

Biological role and pathway

This variant sits within the CD163 gene, which is involved in the anti-inflammatory macrophage (M2) marker pathway. Genes within the Immune System & Inflammation 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.
