rs10421768

What is the rs10421768 variant?

rs10421768 is a SNP (single nucleotide polymorphism) in the HAMP (Hepcidin Antimicrobial Peptide) gene. It belongs to the Vitamin Metabolism category and is part of the Vitamin & Nutrient Metabolism biological cluster. HAMP encodes hepcidin, the master regulator of iron homeostasis that inhibits intestinal iron absorption and macrophage iron release.

Biological role and pathway

This variant sits within the HAMP gene, which is involved in the iron homeostasis regulation pathway. Genes within the Vitamin & Nutrient Metabolism 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.
