HIF1A Gene

Hypoxia Inducible Factor 1 Subunit Alpha (HIF1A) is a gene involved in hypoxia response / angiogenesis / glycolysis that has been studied in relation to immune function, metabolism, and chronic illness. Variants in HIF1A may influence how the body responds to infection, inflammation, and long-term recovery.

What is the HIF1A gene?

HIF1A encodes hypoxia inducible factor 1 subunit alpha, a protein involved in hypoxia response / angiogenesis / glycolysis. It belongs to the Signaling category and is part of the Mitochondrial Energy Production & PEM biological cluster. HIF1A encodes the oxygen-sensitive alpha subunit of HIF-1, the master transcription factor for the cellular hypoxia response.

Biological role and pathway

HIF1A is involved in the hypoxia response / angiogenesis / glycolysis pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Mitochondrial Energy Production & PEM 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 in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

HIF1A and Long COVID / ME-CFS research

HIF-1alpha drives anaerobic metabolism and immune cell reprogramming under hypoxia; variants may affect the cellular response to the hypoxic microenvironments created by Long COVID vascular dysfunction.
