GSTP1 Gene

What is the GSTP1 gene?

GSTP1 encodes glutathione s-transferase pi 1, a protein involved in glutathione conjugation. It belongs to the Metabolism category and is part of the Pharmacogenomics biological cluster. GSTP1 is a glutathione transferase highly expressed in lung and brain that detoxifies reactive oxygen species, electrophiles, and chemotherapy agents. The Ile105Val (rs1695) variant affects substrate specificity.

Biological role and pathway

GSTP1 is involved in the glutathione conjugation pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Pharmacogenomics 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 GSTP1 gene have been studied in relation to metabolism and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.

• rs1695— GSTP1 variant
• rs1138272— GSTP1 variant
• rs947894— GSTP1 variant

Conditions studied in relation to GSTP1

Research into GSTP1 variants has explored associations with the following conditions. These are areas of scientific investigation and do not imply that GSTP1 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 GSTP1 and related genes in the pharmacogenomics 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.
