HMOX1 (rs2071746) is a single nucleotide polymorphism located in the promoter region of the HMOX1 gene, which encodes the enzyme heme oxygenase‑1 (HO‑1). As a regulatory variant, rs2071746 has been studied for its effects on gene expression and on how cells respond to biochemical stressors. HO‑1 catalyzes the breakdown of heme into biliverdin, carbon monoxide, and free iron. Through these products and related signaling, HO‑1 contributes to antioxidant defenses, modulation of inflammatory responses, and protection against cellular stress. Research into promoter variants like rs2071746 focuses on how inherited differences shape these adaptive responses under oxidative or metabolic strain.

Genotypes linked to higher HO‑1 expression or activity may be associated with a stronger inducible antioxidant response, altered iron handling, and shifts in inflammatory signaling; in a test panel this pattern can help explain lower measured oxidative markers relative to expected stress. Conversely, genotypes associated with lower HO‑1 expression may indicate reduced inducible antioxidant capacity and different patterns of heme or iron metabolism, which can correlate with higher oxidative markers or slower recovery from cellular stress. Interpretation depends on the full Cellular Zoomer profile: genetic tendencies alone do not define function. Combine genotype with urine and saliva oxidative, mitochondrial, and detoxification markers to understand actual biochemical balance and resilience.

HMOX1 (rs2071746) is included in the Cellular Zoomer’s antioxidant genetics set to link inherited regulation of HO‑1 with real‑time oxidative damage and detoxification markers. This pairing helps providers distinguish whether measured redox patterns reflect genetic predisposition, current oxidative load, or both, supporting more precise interpretation of cellular stress and resilience.
