ALOX12 Gene

What is the ALOX12 gene?

ALOX12 encodes arachidonate 12-lipoxygenase, a protein involved in 12-HETE platelet and immune cell signaling. It belongs to the Immune Signaling category and is part of the Histamine & MCAS biological cluster. ALOX12 encodes 12-lipoxygenase, which converts arachidonic acid to 12-HETE, a lipid mediator affecting platelet function and pain signaling.

Biological role and pathway

ALOX12 is involved in the 12-HETE platelet and immune cell signaling pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Histamine & MCAS 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.

Known genetic variants

The following variants (SNPs) in the ALOX12 gene have been studied in relation to immune signaling and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs434473— ALOX12 variant
• rs1126667— ALOX12 variant

Conditions studied in relation to ALOX12

Research into ALOX12 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that ALOX12 causes or treats any condition.

Genetic insights from DNA data

Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may include ALOX12 and related genes in the histamine & mcas pathway.

The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. Results are presented in plain English with appropriate scientific context, no medical jargon, no scare tactics. All results should be discussed with a qualified healthcare provider.
